x = 10°
Step-by-step explanation:
(5x + 2) + 38 = 90
5x + 2 = 90 - 38
5x = 52 - 2
5x = 50
x = 50 ÷ 5
x = 10°

Answer: Choice A) -10.73</h3>
Work Shown:
Plug x = 4.3 into the equation given

ŷ = 2.6 − 13.33
ŷ = -10.73
Note: The symbol ŷ is read as "y hat". It's used to estimate the y value when it comes to regression equations.
