Given that f(x) = x2 − 3x + 3 and g(x) = the quantity of x minus one, over four , solve for f(g(x)) when x = 5. (1 point)
1 answer:
Rewrite g(x) as x-1
------
4
and then substitute this result for x in f(x) = x^2 - 3x + 3:
f(g(x)) = (x-1)^2 / 4^2 - 3(x-1)/4 + 3.
At this point we can substitute the value 5 for x:
f(g(5)) = (5-1)^2 / 4^2 - 3(5-1)/4 + 3
= 16/16 - 3(4/4) + 3 = 1 - 3 + 3 = 1
Therefore, f(g(5)) = 1.

Your answer would be 4 because if she spent $20 for 2 pairs you would then know that it would be $10 for 1 pair so it would be $40 for 4 pairs therefor Kerry bought 4 pairs of jeans.Hope it helps you!
The value of x is 5/8.
<u>Step-by-step explanation </u>:
Given,
The lines PQ and RS are parallel to each other. slope of PQ= x-1/4 slope of RS = 3/8 The slopes of parallel lines are equal.
slope of PQ = slope of RS
⇒ x-1/4 = 3/8
⇒ (4x-1)/4 = 3/8
⇒ 8(4x-1) = 4(3)
⇒ 32x-8 = 12
⇒ 32x = 20
x = 20/32
x = 5/8
