Check attached graph of the line in picture

Step-by-step explanation:

Step-by-step explanation:

We have been given an equation y+6=45(x+3) in point slope form.

It says to use the point and slope from given equation to create the graph.

So compare equation y+6=45(x+3) with point slope formula

y-y1=m(x-x1)

we see that m=45, x1=-3 and y1=-6

Hence first point is at (-3,-6)

slope m=45 is positive so to find another point, previous point will move 45 units up then 1 unit right and reach at the location (-2,39).

Now we just graph both points (-3,-6) and  (-2,39) and join them by a straight line. Final graph will look like the line in attached graph.

Final answer:

The y-intercept of function f(x) can be found by using the given points to determine the slope and then plugging in the slope and a point into the point-slope equation. The y-intercept of function g(x) is given by the table. The positive difference in the y-intercept values of f(x) and g(x) is -0.5.

Explanation:

The y-intercept of a linear function represents the value of the function when x is equal to 0. To find the y-intercept of function f(x), we can use the given points (0,1) and (2,7) to determine the slope of the line. The slope is calculated by taking the difference in the y-coordinates and dividing it by the difference in the x-coordinates:

slope = (7 - 1) / (2 - 0) = 3.

Now that we have the slope, we can use the point-slope form of a linear equation to find the equation of the line:

y - y1 = m(x - x1), where (x1, y1) is a point on the line and m is the slope.

Using the point (0,1) and the slope 3, we get:

y - 1 = 3(x - 0).

Simplifying the equation gives us:

y = 3x + 1.

The y-intercept of function g(x) is given by the table as the value of g(x) when x = -1, which is 1.5.

The positive difference in the y-intercept values of f(x) and g(x) is given by:

1 - 1.5 = -0.5.

Answer:

-2.59 = x

Step-by-step explanation:

3+5.25 = 1 - 2.8x

Combine like terms

8.25 = 1-2.8x

Subtract 1 from each side

8.25 -1 = 1-1-2.8x

7.25 = -2.8x

Divide each side by -2.8

7.25/-2.8 = -2.8x/-2.8

-2.589285714 = x

Rounding  

x=-2.59

Answer:

$1062.5

Step-by-step explanation:

Since it is given that Money is increased by 25% from July to December.

Also, Mike deposit $850 in a bank account

Thus, He get money at the end of December = $850 × (100 + 25)%

⇒ Total Money = $850 × 125%

⇒ Total Money = $850 × 1.25

⇒ Total Money = $1062.5

The expression (1/7x + 11/7) can be factored as (x + 11) after dividing each term by 1/7. The factored form simplifies the original expression and represents the common factor, 1/7, that was pulled out.

To factor out 1/7 from the expression (1/7x + 11/7), you can simply divide each term in the expression by 1/7. This is equivalent to multiplying each term by the reciprocal of 1/7, which is 7/1.

Starting with the expression (1/7x + 11/7):

(1/7x) ÷ (1/7) = x

(11/7) ÷ (1/7) = 11

So, factoring out 1/7, the expression becomes x + 11.

Therefore, the factored form of (1/7x + 11/7) is (x + 11).

512 baseball cards

Step-by-step explanation:

At 13, Stephanie had 137 baseball cards.

There are 28-13 = 15 years between 13 and 28

For those 15 years, she got 25 cards a year.

15 * 25 = 375

In those 15 years, she got 375 cards.

She started with 137, and she gained 375.

137+375 = 512

She now has   512 cards.

The equivalent expression of the expression 1.18 x 0.6 will be;

⇒ (118 x 1/100) x (6 x 1/10)

Option B is true.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ 1.18 x 0.6

Now,

Solve the expression as;

The expression is,

⇒ 1.18 x 0.6

Since, 1.18 = 118 x 1/100

And, 0.6 = 6 x 1/10

Thus, The equivalent expression is,

⇒ 1.18 x 0.6 = (118 x 1/100) x (6 x 1/10)

Therefore, The equivalent expression of the expression 1.18 x 0.6 will be;

⇒ (118 x 1/100) x (6 x 1/10)

Option B is true.

Answer:

30 students

Step-by-step explanation:

Yesterday: 1/3 of the 75 students (75 / 3) = 25 students

There are now 50 students remaining to give their speeches.

Today: 2/5 of the 50 students (50 / 5 = 10 x 2 ) = 20 students

50 - 20 = 30 students remaining to give their speeches.

Therefore, 30 students still haven't given their speeches.

To find out how many students still haven't given their speeches, we first need to calculate the number of students who gave their speeches yesterday and today. Since there were 75 students in total and 1/3 of them gave their speeches yesterday, we multiply 75 by 1/3:

75 * 1/3 = 25 students

This means that 25 students gave their speeches yesterday. To find out how many students were left for today, we subtract the number of students who gave speeches yesterday from the total number:

75 - 25 = 50 students remained

Today, 2/5 of the remaining students gave their speeches. We calculate this by multiplying the number of remaining students by 2/5:

50 * 2/5 = 20 students

Therefore, 20 students gave their speeches today. Now, we subtract the number of students who have given their speeches today from the remaining number of students to find out how many have not given their speeches yet:

50 - 20 = 30 students

Thus, 30 students still haven't given their speeches.

Answer:

the first one is -1 15/18 the next one is -1 14/18

Step-by-step explanation:

The mixed numbers that are equivalent to −1 5/6 ​ and​ −1 7/9 are −1 15/18 and −1 14/18, respectively.

The least common multiple that is divisible by both a and b is the smallest positive integer, lowest common multiple, or smallest common multiple of two numbers a and b, generally indicated by LCM.

The LCD is the lowest common denominator for any two or more fractions. Now, for the given mixed numbers the two fractions given are 5/6 and 7/9, therefore, their LCD is the LCM of the denominator, in this case, the denominators are 6 and 9, therefore, the LCM of these two is 18.

Further to get the mixed number, the fraction is needed to be multiplied such that their denominator becomes 18.

Multiply both the numerator and the denominator by 3, therefore,

(5/6) × (3/3) = 15/18

Multiply both the numerator and the denominator by 2, therefore,

(5/6) × (2/2) = 14/18

Thus, the mixed fractions can be written as,

hence, the mixed numbers that are equivalent to −1 5/6 ​ and​ −1 7/9 are −1 15/18 and −1 14/18, respectively.

Problem 2) ASA

Problem 3) AAS

Problem 4) Neither

Problem 5) AAS

Problem 6) Neither

==============================

Explanation:

Any time we have ASA is when we can match up two pairs of angles and a pair of sides between the two pairs of angles. With problems 1 and 2, this happens. The corresponding angles that are congruent are the ones that have the same angle markers.

AAS is slightly different from ASA in that the side is not between the angles. This happens with problem 3 and problem 5. For problem 3, for instance, the second pair of angles are the two vertical angles. These angles are not marked, but they are congruent due to the vertical angle theorem. The same thing can be said about problem 5 as well.

With problem 4 and problem 6, we don't have any information about any pairs of angles, so we can't use AAS or ASA at all. We don't know if the triangles are congruent or not. They might be, but we simply don't have enough info to say either way.

In the number 526, the underlined digit '5' represents the 100's place, so its value is not simply 5, but 500. A helpful tool to work with such problems is the place value chart.

In the number 526, the emphasized or underlined digit represents the 100's place. So, the value of this specific digit, which happens to be 5, isn't simply 5 but 500 in the context of this particular group of digits. You can easily understand this by breaking down the number: 526 equals 500 (5 hundreds) plus 20 (2 tens) plus 6 (6 ones).

Another easy method to identify the value of an underlined or specific digit in a number is by knowing the place value chart, which runs from right to left as: Ones, Tens, Hundreds, Thousands, and so on. The third digit from right is the Hundreds place, and since in 526, 5 is in this position, its value becomes 500.
