Answer:
The answer to your question is (g°f)(x) = 7
Step-by-step explanation:
Data
g(x) = 3x - 2
f(x) = x + 5
(g°f)(-2)
Process
1.- Evaluate g(x) on f(x)
(g°f)(x) = 3(x + 5) - 2
-Expand
(g°f)(x) = 3x + 15 - 2
-Simplify
(g°f)(x) = 3x + 13
2.- Evaluate (g°f)(x) on -2
(g°f)(-2) = 3(-2) + 13
-Expand
(g°f)(-2) = -6 + 13
-Simplify
(g°f)(x) = 7

Okay, so this is a right angle. That means it is 90 degrees.
So far we know that on side of the angle is 47 degrees.
To get the other angle we will just subtract 90 - 47 = 43
Answer:
W(x) = $50 + ($14/hr)x
Step-by-step explanation:
Let W(x) represent Wendy's earnings, and x the # of hours she worked.
Then W(x) = $50 + ($14/hr)x
Answer:
x = 47
Step-by-step explanation:
86° and 2x° are supplementary angles, which means that added together they should equal 180° (which is a line). Aka
86 + 2x = 180 (Let's solve for x) (subtract both sides by 86 to get x on one side)
2x = 94 (divide both sides by 2 to get x by itself)
x = 47
