Answer: i would say no
Step-by-step explanation:
To write a linear equation in standard form, move each variable term to the left side of the equation and simplify.
Ax+By=C
Since x
is on the right side of the equation, switch the sides so it is on the left side of the equation.
3x=y
Move y
to the left side of the equation because it contains a variable.
3x−y=0
Answer:
no but see explanation
Step-by-step explanation:
the equation of a line in standard form is
Ax + By = C ( A is a positive integer and B, C are integers )
rearrange y = 3x into this form
subtract y from both sides
0 = 3x - y, hence
3x - y = 0 ← in standard form

Answer:
Graph B has 1 real root
Graph A has a negative discriminant
Graph C has an equation with a=1, b=4 , c=-2
Step-by-step explanation:
If we look at the graph, Graph A never crosses the x axis, so it does not have any real roots.
Graph B touches the x axis, but does not cross so it has 1 real root
Graph C crosses the x axis 2 times, so it has 2 real roots.
We know from the discriminant b^2-4ac
If the discriminant >0 it has 2 real roots, so Graph C has a positive discriminant
If the discriminant =0 it has 1 real root, so Graph B has a zero discriminant
If the discriminant <0 it has 0 real roots, so Graph A has a negative discriminant
If we have a=1, b=4 , c=-2
b^2-4ac = 4^2-4(1)(-2) = 16+8 = 24 >0 This must be Graph C
By the end of Monday, a grocery distribution center has 240 cases of green beans in its warehouse. Every day, the center delivers 18 cases of green beans to various stores. How many cases of green beans does the warehouse have after deliveries on Tuesday, Wednesday, Thursday?
A. 240, 204, 168
B. 222, 204, 186
C. 256, 276, 294
D. 240, 222, 204
Answer b
Step-by-step explanation:
the answer is b becasue on tuesday you deliver 18 then you now have 222 cases on tuesday and on wednesday you have 204 now because you delivered 18 then on thursday you now have 186 because you delivered 18 and alltogether you delivered 54 cases in three days so 240 minus 54 equals 186 because each day you deliver 18 and 18 times 3 is 54 so 54 minus 240 eguals 186 and 186 plus 18 is 204 and 204 plus 18 is 222 so b would be the correct answer

11z 5 = 9z + 7 how do u solve this?
Answer:Z=1
Step-by-step explanation: if it is 11z+5, then... minus 9z on each side to get 2z+5=7. Minus 5 on each side to get 2z=2. Divide bboth sides by two to get 1z=1.
You solve the equation 11z + 5 = 9z + 7 by first isolating for z terms and constant terms on opposite sides of the equality, then dividing by the coefficient of z to get z = 1.
Explanation:To solve the equation 11z + 5 = 9z + 7, we need to get all the z terms on one side of the equation and the constant terms on the other side. We start by subtracting 9z from both sides to get 2z + 5 = 7. Then, subtract 5 from both sides to get 2z = 2. Finally, divide both sides by 2 to solve for z which gives us z = 1.

An isosceles triangle with vertices labeled R, S, and T. Side R T is the base. Sides R S and side S T are equal. Angle R is labeled as 3 x degrees, angle S is labeled as 2 x degrees, and angle T is labeled as 3 x degrees.
Answer:
∠S = 45°
Step-by-step explanation:
As given in the question, ∠R = 3x ; ∠S=2x ; ∠T=3x
So by using angle sum property of a triangle that sum of all the angles of a triangle is 180°.
We get, ∠R+∠S+∠T = 180
[tex]3x+2x+3x=180\\8x=180\\x=\frac{180}{8}[/tex]
So, ∠S=2x
∠S=[tex]2\cdot \frac{180}{8}[/tex]
∠S=45°
Answer:
m∠S= 45°
Step-by-step explanation:
Given an isosceles triangle ABC.
& m∠R = m∠T = 3 x, m∠S = 2 x
The sum of all the angles of triangle is equal to 180°
⇒ m∠R + m∠S + m∠T = 180°
3 x + 2 x + 3 x = 180°
⇒ 8 x = 180°
⇒ x = [tex]\frac{180}{8}[/tex]
⇒ x = [tex]\frac{45}{2}[/tex]
Hence, m∠S = [tex]2\times\frac{45}{2}[/tex]

What’s the slope between (19,3) and (20,3)
What is the value of X?
Answer:
w = 31
Step-by-step explanation:
To find the value of w:
We know that the three angles in a triangle add to 180 degrees
w + w + (4w-6) =180
Add like terms
6w-6 = 180
Add 6 to each side
6w -6+6 =180+6
6w = 186
Divide each side by 6
6w/6 = 186/6
w = 31

Toby found a $52 wallet on the clearance rack for 60% off. If sales tax is 6.25%, how much will he pay in total?
Toby has to pay 22.1$ in total for the wallet.
What is percentage?A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to compute a percentage of a number, we should divide it by its whole and then multiply it by 100. The proportion, therefore, refers to a component per hundred. Per 100 is what the term percent signifies. The letter "%" stands for it.
Given that, Toby found a $52 wallet on the clearance rack for 60% off.
So.
The price of wallet after discount = 52 * (1 - 60%)
The price of the wallet after the discount = 52*0.4
The price of the wallet after the discount = 20.8
Since there is a sales tax of 6.25%
Thus the purchasing Price of the wallet = 20.8(1 + 6.25%)
the purchasing Price of the wallet = 22.1
therefore, If the sales tax is 6.25%, he will pay $22.1 in total.

What does The difference of two numbers by 5 look like
Answer:
Step-by-step explanation:
Let the larger number = x
Let the smaller number = y
I can't really tell if I'm reading it correctly, but I think the answer is
x - y = 5
Answer:
Step-by-step explanation:
Suppose you have given two numbers say (x and y ).
Now we can have 3 conditions here:
i . x and y are equal
ii. x is greater than y
iii . y is greater than x .
For x and y are equal : - Difference between two numbers will be zero.
For x and y greater or lesser :- There will be some difference between two numbers x and y. And if this difference between x and y is 5, then it will look like:
x is greater than y
x - y = 5
or
y is greater than x
y - x = 5

a milkyway bar is 5 inches long. The bar will be split into two pieces. For each situation find the length in inches of the two pieces and write your answer as the ratio of the larger piece to the smaller piece. Show your work
A) one piece is 1 inch longer than the other?
B) one piece is 60% of the bar
HELPPPPPPPP ASAP
Answer:
A)one is 3 inches and the other is 2 inches.2:5 and 3:5
B)It would be still b three and two because 3/5 of the chocolate bar is 60% and 2/5 is 40%.
Step-by-step explanation:
A) If the bar is 5 inches long and it is broken into two pieces with one that measures an inch longer then you would find that if broken in half it would be 2.5, so if you take the other point 0.5 off of the other 2.5 and add it to the other half then it would have on piece that is an inch longer than the other piece.3+2=5
B) 5(0.6) =3
For Scenario A, the Milky Way bar is divided into two pieces where one piece is 1 inch longer than the other, resulting in lengths of 3 inches and 2 inches, with a ratio of 3:2. In Scenario B, one piece is 60% of the entire bar, equating to 3 inches and 2 inches for the two pieces, again with a ratio of 3:2.
A Milky Way bar is 5 inches long and is split into two pieces.
Scenario A: One Piece Is 1 Inch Longer Than the Other
Let's denote the length of the shorter piece as x. According to the problem, the longer piece would then be x + 1 inch. Since the two pieces together must add up to the total length of the bar, which is 5 inches, we can set up the following equation:
x + (x + 1) = 5 inches
2x + 1 = 5 inches
2x = 5 inches - 1 inch
2x = 4 inches
x = 2 inches
The shorter piece is 2 inches, meaning the longer piece is 2 inches + 1 inch = 3 inches.
The ratio of the longer piece to the shorter piece is therefore 3:2.
Scenario B: One Piece Is 60% of the Bar
In this case, one piece is 60% of 5 inches. We calculate this piece as follows:
60% of 5 inches = 0.60 * 5 inches
= 3 inches
Since one piece is 3 inches, the other piece must be 5 inches minus 3 inches, which is 2 inches. The ratio of the larger piece to the smaller piece is 3:2, the same as in Scenario A.

Keisha and her friends visit the concession stand at the basketball game. The stand charges $2 for a hotdog and $1 for a drink. The friends buy a total of 8 items for $11. How many hot dogs and how many drinks did they buy? Show your work and explain your reasoning. (please help, for math homework)
Answer:
They bought 3 hot dogs and 5 drinks
Step-by-step explanation:
Well, its mostly guess and check.
x=hot dogs y= drinks x+y=8
2x + 1y =11
2(1) + 1(7) = 9 (wrong answer)
2(2) + 1(6)= 10 (wrong answer)
2(3) + 1(5) = 11 (right answer)
The reason I pick these numbers is because the x and the y need to add up to 8 and as you can see on each try they added up to 8 but it also had the equation itself had to add up to $11. So, you substitute the numbers that add up to 8 to x and y to make sure the equation equals 11.
Final answer:
Keisha and her friends purchased 3 hotdogs and 5 drinks at the concession stand. This was determined by setting up a system of equations based on the given costs for items and the total amount spent and solving for the variables representing hotdogs and drinks.
Explanation:
To solve Keisha's concession stand problem, we need to use a system of equations. Let's define two variables: x for hotdogs and y for drinks. According to the problem, the friends bought a total of 8 items for $11. The price is $2 per hotdog and $1 per drink. We can set up the following equations:
1) x + y = 8 (for the total number of items)
2) 2x + y = 11 (for the total cost)
Solving the system, we can subtract the first equation from the second to find the number of hotdogs:
2x + y - (x + y) = 11 - 8
x = 3
Now, we substitute x back into the first equation to find y:
3 + y = 8
y = 5
Therefore, Keisha and her friends bought 3 hotdogs and 5 drinks.
