Hi!
30 = x
f(x) = -1/5x - 14 find x when f (x) = -8
Set the equation equal to -8
-8 = -1/5x - 14
Add 14 to both sides.
6 = -1/5x
Multiply both sides by -5.
30 = x
Hope this helps! :D
52° would be the value of x
Answer: -7
Step-by-step explanation:
Check the picture below.
surely you know how much that is.
let's first convert the mixed fraction to improper, and then proceed.
