Answer: first problem 3rd choice The graph shifts vertically up 5 units
11.) the y intercept is -5
19.) f(-8) = -18
last item third choice All real numbers such that are ≥ 0 and ≤ 40
Step-by-step explanation:
19.) f(x)=2(-8 -3) + 4
2 (-11) + 4
-22 + 4
f(-8) = -18
Let the number be x.
Tripled the number = 3x
Tripled the number again = 9x
9x = 891
x = 99
Answer: 99
9b+63 = 72
9b = 9 (subtract 63 from both sides)
b = 1 (divide both sides by 9)
