To find G of F first solve f(x) by replacing x with -7
F(x) = x^2 +6
= -7^2 +6
= 49 +6 = 55
So f(x) = 55
Now replace the X in the g(x) equation with 55
g(x) = x+8 / x
= 55+8 / 55
= 63/55
The last choice is the correct answer.
Isolate x
So xy - 2 = k
Then
xy = k + 2
x = (k+2)/y
Answer:
$48
Step-by-step explanation:
80 x 0.4 = 32
80 - 32 = 48
Hoped it Helped :-)
Th answer is x-2.hope this helps
Philip rides to school in 6 2/5 minutes.....it takes Joey 4 1/2 times as long...
4 1/2 * 6 2/5 =
9/2 * 32/5 =
144/5 =
28 4/5 minutes <== Joey's time to get to school
