If f(x) = -2x + 8, and f(k) = -10, what is the value
of k? step by step please

Hello there!

We are given the function:

We want to find the value of k. First, we know that f(k) is -10. We substitute x = k and f(x) = -10.

Solving the equation. First, we subtract both sides by 8.

Divide both sides by -2.

Therefore, k = 9

When we substitute k = 9 in f(k), the value is -10.

Let me know if you have any questions!

its c or d   take a lucky guess my dude

the length of o'p' is .

step-by-step explanation:

it is given that the quadrilateral m'n'o'p' is the image of quadrilateral mnop after dilation.

the center of dilation is origin and the scale factor is 1.5.

in dilation the image and preimge are similar figures. it means the sides of image and preimage are proportional.

the scale factor is defined as

the scale factor is 1.5.

multiply both sides by op.

note: if the value of op is given, then multiply the value of op with 1.5 to get the length of side o'p'.

therefore length of o'p' is .
