Answer:

The answer to your question is B = 82.5°

Step-by-step explanation:

Data

A and B are supplementary angles

A = x

B = x - 15°

Process

1.- Write and equation to solve this problem. As these angles are supplementary the sum equals 180°.

              A + B = 180°

2.- Substitution

              x + x - 15 = 180

3.- Solve for x

              2x = 180 + 15

              2x = 195

                x = 195 / 2

                x = 97.5

4.- Find the measure of angle B

             B = x - 15

             B = 97.5 - 15

             B = 82.5°

Answer:

A is the Answer

Step-by-step explanation:

Since the population is being split up into 2 divisions out of 5,000.

This means District X and Y must add up 5000.

x + y = 5000

District X and Y must differ no more than 500 people.

So this means that X and Y total people difference cannot be over 500 people. So the equation for this is

x - y \leqslant 500

A shows this so A is the answer.

Answer:  

2x + (-2x + 3) = 3

2x - 2x +3

0 + 3

3

2x-7 + (-2x) = -7

2x -2x - 7

0 -7

-7

-(5x -1) + 5x = 1

-5x +1 + 5x

-5x + 5x + 1

0 + 1

1

Step-by-step explanation: In addition, the parentheses help identify the individual addends. If adding a negative number, it is the same as subtracting. If there is a negative sign outside the parentheses, as in example c, you must distribute it: the signs of the numbers within the parentheses must be reversed when the parentheses are removed.

Answer:

Graph A

Step-by-step explanation:

y =  {x}^{2}  - 6x - 7 \\ plug \: y = 0 \\  {x}^{2}  - 6x - 7 = 0 \\  {x}^{2}  - 6x + 9 = 7 + 9 \\ (x - 3)^{2}  = 16 \\ (x - 3) =  \pm 4 \\ x = 4 + 3 \: or \: x =  - 4 + 3 \\ x = 7 \: or \: x =  - 1

Its mean graph should intersect x axis at x = 7 and x = - 1. This everything is satisfied by graph A.
