The correct answer is 5 1/2
Answer:
D. 80
Step-by-step explanation:
Given:
f(x) = 5x - 4,
g(x) = x² - 1
Required:
(g o f)(-1)
SOLUTION:
(g o f)(-1) = g(f(-1))
Plug in -1 for x into the function, f(x) = 5x - 4:
g(f(-1)) = g(5(-1) - 4)
= g(-5 - 4)
= g(-9)
Plug in -9 for x in the function, g(x) = x² - 1
g(-9) = (-9)² - 1
= 81 - 1
= 80.
Therefore, (g o f)(-1) = g(f(-1)) = 80
D. 80 is the correct answer.
Hi there!
This isn't true, because if you were to take 10% of, let's say, 100 (which is 10), and if you were to take 20% of 20 (which is 5), 5 is still smaller than 10.
Hope this helps!
Step-by-step explanation:
In 20 seconds, Ebonie ran 80 feet
In 1 second,. Ebonie ran. 80/20 feet
= 4 feet
so, Ebonie 's speed is 4 ft/sec.
and
In 12 seconds , Trinidi ran 60 ft
In 1 second,. she ran 60/12
= 5 ft
so , Trinity's speed is 5ft/ sec
