Question

Help! If f(x)= 6−5x, the what is f(4)?

Answer 1

replace your x by 4

Answer 2

f(x)=6-5*4

Answer 3

plug in 4 for x same as last time

Answer 4

-14?

Answer 5

6-20= -14 so yes

Answer 6

How would I set up this one? f(x)= −2x + 15 and f(x)= −11, find x.

Answer 7

If f(x) = -2x + 15 and f(x) = -11, then these are both equal to each other, so, -11 = -2x + 15

Answer 8

How I would I solve that?

Answer 9

First, how do we get + 15 to the other side?
