The answer is a. -7
1. Find g(2).
2. Find f(g(2)).
g(x) = x² - 6x - 7
x = 2 ⇒ g(2) = ?
g(2) = 2² - 6·2 - 7 = 4 - 12 - 7 = -15
2. f(x) = x + 8
g(2) = -15
f(g(2)) = f(-15) = -15 + 8 = -7
Answer:
Step-by-step explanation:
2 hours × 60 km/hour = 120 km
390-120 = 270 km remaining
270 km/(3 hours) = 90 km/hour
Answer:
JK = 11
Step-by-step explanation:
JK ≅ JM
where
JK = 3x - 16
JM = 2x - 7
3x - 16 = 2x - 7
group like terms
3x - 2x = 16 - 7
x = 9
<u>plugin x=9 into JK</u>
JK = 3x - 16
JK = 3(9) - 16
JK = 11
The answer is none. There are no solutions
Change 212,514 into 215,000.
Change 396,705 into 400,000.
--------
Estimate:
215,000 + 400,000 = 615,000
Therefore:
212,514 + 396,705 ≈ 615,000
