The answer is -8/15 because you need to cancel out the variables first
Answer: x = 35°
Steps:
(x + 10) + (3x - 5) + x = 180
x + 10 + 3x - 5 + x = 180
5x + 10 - 5 = 180
5x + 5 = 180
5x = 180 - 5
5x = 175
x = 175/5
x = 35
Check:
(x + 10) + (3x - 5) + x = 180
(35 + 10) + (3*35 - 5) + 35 = 180
45 + 100 + 35 = 180
180 = 180 ✅

Answer:
D
Step-by-step explanation:
<u>How to find the inverse of a function.</u>
- Replace f(x) with y
- Swap x and y places. (sign doesn't matter here.)
- solve for y.
f(x) = 8√x
y = 8√x
x = 8√y
x^2 = (8√y)^2
x^2 = 64y
y = x^2 / 64
= (1/64) x^2
