Question

For f(x)=-5x+10, what is the value of x for which f(x) =35

X = 5
None are correct
X=3
X=-4
X=-5

Answer 1

-5

Explanation:

f(x) =35

f(x) = -5x +10

equate the two equations:

-5x +10 =35

-5x =35-10

-5x =25

x = 25/-5

x = -5

Answer 2

x=-5. -5x+10 replace the x with -5, multiply, add ten, and you'll get f(x)= 35
