Dose anyone know what to do to solve this? :(

If h(x) = −4x − 10, find h(−5).

−30

1.25

10

−1

Answer 1

susbstitute (-5) for x

Answer 2

So the quation is -4*5-10?

Answer 3

-4*-5-10

Answer 4

oh ok so what now i solve that? would it be 10?

Answer 5

oh ok what about this one? Given the function f(x) = 2(x + 6), find x if f(x) = 22.

56

5

38

17

Answer 6

hmm... i think that would be just be 2(22+6)

Answer 7

ok ty and last one :P Given the function f(x) = −2x + 8, find x if f(x) = 14

−20

36

−3

−11

Answer 8

yeah, same as the others -2(14+8) think of f(x) being y so sorta like the equation y= -2x+8 if that made any sense

Answer 9

I dont get how to solve that one

Answer 10

im sorry, i wrote the equation wrong i meant -2(14) +8

Answer 11

ok thanks so much!
