Explanation:
Each is a reflection of the other over the x-axis. Their x-coordinates are the same, so they lie on the same vertical line. Their y-coordinates are opposites, so they are equal and opposite distances from the x-axis.
Deepak is a landscaper who charges $30 for each job he does plus an additional $15 for each hour he works. He only accepts jobs if he will earn at least $90 the job. He writes this inequality to determine x, the number of hours he must work during each job in order to accomplish this.
Answer:
A.) Deepak can only accept jobs that last 4 or more hours.
Step-by-step explanation:
Hope this helps :)
add a thanks...
Deepak must work 4 or fewer hours to earn at least $90 per job.
Explanation:The question is asking about the inequality that Deepak, a landscaper, writes to determine the number of hours he must work during each job in order to earn at least $90 the job. We can break down the equation as follows:
Let x be the number of hours Deepak works.
The equation can be written as: $30 + $15x ≤ $90.
To solve for x, we subtract $30 from both sides: $15x ≤ $60.
Then, we divide both sides by $15: x ≤ 4.
Therefore, Deepak must work 4 or fewer hours to earn at least $90 per job.

Jenna says that no row or column contains products with only odd numbers do you agree explain.
Jenna's claim that no row or column contains products with only odd numbers is wrong. A counterexample can be found by examining a matrix.
Explanation:Jenna claims that no row or column contains products with only odd numbers. Let's examine whether this statement is true or not. Let's consider a matrix and see if we can find a row or column that contains products with only odd numbers.
For example, let's take the following matrix:
1 2
3 4
In this matrix, we can see that the 1st row contains the product 2 and the 2nd row contains the product 12 which are both even numbers.
So, Jenna's statement is not true as we have found a row that contains products with only even numbers.

What is the equation in point slope form of a line that passes through the points (-8,2) and had a slope of 1/2
Answer:
[tex]y-2=\dfrac{1}{2}(x+8)[/tex]
Step-by-step explanation:
It a line passes through the point [tex](x_1,y_1)[/tex] with slope m, then the point slope form of the line is
[tex](y-y_1)=m(x-x_1)[/tex] ....(i)
It is given that line passes through the point (-8,2) and had a slope of 1/2.
We neeed to find the equation in point slope form of the line.
Substitute [tex]x_1=-8,y_1=2\text{ and }m=\dfrac{1}{2}[/tex] in equation (i).
[tex](y-(2))=\dfrac{1}{2}(x-(-8))[/tex]
[tex]y-2=\dfrac{1}{2}(x+8)[/tex]
Therefore, the point slope form of the line is [tex]y-2=\dfrac{1}{2}(x+8)[/tex].
i need to solve this equation: x= r-h/ y
for h and then for r
Answer:
[tex]h=r-xy[/tex]
[tex]r=xy+h[/tex]
Step-by-step explanation:
[tex]x=\frac{r-h}{y}[/tex]
Solve the equation for h
We need to get 'h' alone
[tex]x=\frac{r-h}{y}[/tex]
multiply y on both sides
[tex]xy=r-h[/tex]
Now add h on both sides
[tex]xy+h=r[/tex]
Subtract xy from both sides
[tex]h=r-xy[/tex]
Now solve the equation for 'r'
[tex]x=\frac{r-h}{y}[/tex]
multiply y on both sides
[tex]xy=r-h[/tex]
Now add h on both sides
[tex]xy+h=r[/tex]
[tex]r=xy+h[/tex]

Sara is selling cookies and brownies as a fundraiser for the school band. She charges $2.25 for two cookies and one brownie. She charges $5.75 for four cookies and three brownies. How much does Sara charge per cookie? How much per brownie?
A. $0.50 per cookie, $1.25 per brownie
B. $0.75 per cookie, $1.50 per brownie
C. $0.25 per cookie, $1.00 per brownie
D. $1.00 per cookie, $1.00 per brownie
Answer:
The cost of the $0.5 per cookies and $1.25 per brownie.
Option (A) is correct.
Step-by-step explanation:
Let us assume that the cost of the cookies =x
Let us assume that the cost of the brownie = y
As given
Sara is selling cookies and brownies as a fundraiser for the school band.
She charges $2.25 for two cookies and one brownie.
Than the equation becomes
2x + y = 2.25
She charges $5.75 for four cookies and three brownies.
4x + 3y = 5.75
Than two equation are
2x + y = 2.25 and 4x + 3y = 5.75
Multiply 2x + y = 2.25 by 3 and subtracted from 4x + 3y = 5.75
4x - 6x + 3y - 3y = 5.75 - 6.75
-2x = - 1
2x = 1
[tex]x = \frac{1}{2}[/tex]
x = $0.5
Put in the equation 2x + y = 2.25
2 × 0.5 + y = 2.25
1 + y = 2.25
y = 2.25 - 1
y = $1.25
Therefore the cost of the $0.5 per cookies and $1.25 per brownie.
Option (A) is correct.
Answer:
A is correct
Step-by-step explanation:
In the talent show, 6 students plan to sing, 7 students plan to dance, and 2 students plan to tell jokes. Rick said that the ratio of singers to joke-tellers is 6 to 2. Leah said that the ratio of joke-tellers to singers is 1 to 3. Who is correct? Explain why.
Leah is correct because the ratio of 6 singers to 2 joke-tellers simplifies to 3 to 1. When we reverse this ratio to represent joke-tellers to singers, it becomes 1 to 3, which is what Leah stated
The question is asking us to compare two different ratios and decide which one is correct. Rick stated the ratio of singers to joke-tellers is 6 to 2. In its simplest form, this ratio can be reduced to 3 to 1 when we divide both numbers by 2. On the other hand, Leah stated the ratio of joke-tellers to singers is 1 to 3, which is the inverse of the first ratio.
Since the ratio of singers to joke-tellers is indeed 6 to 2, which simplifies to 3 to 1, that means for every 3 singers, there is 1 joke-teller. Therefore, Leah's statement of the ratio is correct, as it provides the simplified form while Rick gives the unsimplified form. The order of terms in a ratio is important, and Leah's presentation maintains the correct order while also presenting the simplest form of the ratio

Miss Marcus Bulletin Board is 7 ft long and 4 feet High she has 26 ft of board to use Miss Marcus pool supplies 7 time 4 equals 28 to find the exact amount of the board she needs she concludes that she does not have enough border board for the bulletin board do you agree
Final answer:
Yes, I agree that Miss Marcus does have enough board for the bulletin board for the given information
Explanation:
The student is trying to determine if Miss Marcus has enough board to use for her bulletin board. The student calculates the area of the bulletin board as 7 ft x 4 ft = 28 ft². However, the student concludes that Miss Marcus does not have enough board because she only has 26 feet of board to use. This is incorrect, as 26 ft is greater than 28 ft². Therefore, Miss Marcus does have enough board for the bulletin board.

[tex]m=\frac{1}{2}[/tex]
now, we can use point slope form of line
[tex]y-y_1=m(x-x_1)[/tex]
we can plug values
[tex]y+3=\frac{1}{2} (x-0)[/tex]
[tex]y+3=\frac{1}{2}x[/tex]
[tex]y=\frac{1}{2}x-3[/tex]

Which one of the following is an arithmetic sequence?
A. −2, 1, 4, 7, 10, . . .
B. 2, 3, 5, 7, 11, 13, 17, . . .
C. 5, 0, −1, −3, −7, . . .
D. .35, .5, .85, 1.1, 1.22, . . .
Final answer:
Option A (-2, 1, 4, 7, 10, ...) is an arithmetic sequence because there is a consistent common difference of +3 between each term. The other options do not show a constant difference between terms, so they are not arithmetic sequences.
Explanation:
To determine which of the sequences is an arithmetic sequence, we look for a constant difference between successive terms. An arithmetic sequence is a sequence of numbers in which each term after the first is found by adding a constant, known as the common difference, to the previous term.
A. −2, 1, 4, 7, 10, . . . - The difference between terms is consistently +3, so this is an arithmetic sequence.
B. 2, 3, 5, 7, 11, 13, 17, . . . - The sequence consists of prime numbers and does not have a consistent difference. Not an arithmetic sequence.
C. 5, 0, −1, −3, −7, . . . - The differences between terms here change; they are not constant. Not an arithmetic sequence.
D. .35, .5, .85, 1.1, 1.22, . . . - The differences between terms do not remain the same, so it's not an arithmetic sequence.
Our answer is A: −2, 1, 4, 7, 10, . . .. This is the only arithmetic sequence from the given options as it has a consistent common difference of +3 between each term.
The volume of a rectangular prism can be computed using the formula V = lwh. What is the height of a prism that has a volume of 2376 cubic centimeters, a length of 18 centimeters, and a width of 11 centimeters
Answer:
The height of the prism is approximately [tex]\(12\)[/tex] centimeters.
Explanation:
To find the height ([tex]\(h\)[/tex]) of the prism, we can rearrange the formula for volume to solve for [tex]\(h\):[/tex]
[tex]\[ V = lwh \][/tex]
We can rewrite this formula to solve for [tex]\(h\):[/tex]
[tex]\[ h = \frac{V}{lw} \][/tex]
Given:
- Volume ([tex]\(V\)[/tex]) = 2376 cubic centimeters
- Length ([tex]\(l\)[/tex]) = 18 centimeters
- Width ([tex]\(w\)[/tex]) = 11 centimeters
Substitute these values into the formula to find the height:
[tex]\[ h = \frac{2376}{18 \times 11} \][/tex]
[tex]\[ h = \frac{2376}{198} \][/tex]
[tex]\[ h \approx 12 \text{ centimeters} \][/tex]
So, the height of the prism is approximately [tex]\(12\)[/tex] centimeters.

A plumber charges $55 for a service call plus $35 per hour. If the plumber's bill was $160, how many hours was he there?
Answer:
Plumber worked for 3 hours.
Step-by-step explanation:
A plumber charges $55 for a service call plus $35 per hour.
Let he works for x hours.
Then for x hours of work charges = $35x
Since plumber charges $55 as a fixed charge so the total charges will be = 55 + 35x
This total amount charged by the plumber equals to $160
and the equation representing this situation will be
55 + 35x = 160
35x = 160 - 55
35x = 105
x = [tex]\frac{105}{35}[/tex]
x = 3 hours
Therefore, he worked for 3 hours.

A turtle fell to the bottom of a deep well. The turtle climbed up 2 meters on the first day, but slipped back 1 meter as he rested. The second day, the turtle climbed double the distance of the previous day, but slipped and lost ½ of the day’s climbed distance as he rested. This pattern continued until the end of the fourth day, when the turtle realized he was halfway to the top of the well. How deep was the well?
Analyzing the climbing pattern of the turtle for four days shows that it climbed 15 meters which is halfway to the top, thus the entire depth of the well is 30 meters.
The question asks for the determination of the depth of a well based on a pattern observed in a turtle's attempt to climb out of it. To do this, we need to analyze the climbing and slipping pattern for four days until the turtle is halfway out of the well.
On the first day, the turtle climbed up 2 meters and slipped back 1 meter, netting a 1 meter gain. On the second day, the distance climbed is double that of the previous day (2 meters x 2 = 4 meters), but the turtle loses half of it while resting, which means a gain of 2 meters for the second day (4 meters / 2 = 2 meters). Following the pattern:
Day 1: +2 - 1 = +1 meterDay 2: +(2 x 2) - (4 / 2) = +2 metersDay 3: +(4 x 2) - (8 / 2) = +4 metersDay 4: +(8 x 2) - (16 / 2) = +8 metersThe total distance climbed after four days is 1 + 2 + 4 + 8 = 15 meters. Since this is halfway to the top, the entire depth of the well would be 15 meters imes 2 = 30 meters.
1.56 x 10 to the 4th power in Standard notation
To write 1.56 × [tex]10^{4}[/tex] in standard notation, we will first begin with
1.56. Next, we look at the exponent. The exponent is 4 so this tells us we need to move the decimal point 4 places to the right.
1.56 → 15600.
Therefore, 1.56 × [tex]10^{4}[/tex] is written in standard notation as 15,600.
