Which equation represents "the sum of eight times a number and seven is twice the number"? 8(7 + 2n) 8n = 7 + 2n 7n + 8 = 2n 8n + 7 = 2n

D.

Step-by-step explanation:

Let N represent the number.

We are asked to find the equation that satisfies the given description.

8 times the number would be .

The sum of eight times a number and seven would be .

Twice the number would be .

To find our required equation, we will equate the sum of eight times a number and seven to twice the number as:

Therefore, option D is the correct choice.

b) k’(6, 4); l’(3, 3)

step-by-step explanation:

a 270° clockwise rotation maps every point (x, y) to (y, -x). (it negates the x-coordinate and then switches it and the y-coordinate.)

this means the endpoints of the side congruent to kl, k' and l', would be mapped as:

k'(-4, 6)→(6, 4)

l'(-3, 3)→(3, 3)
