F(g(x)) = [(-7x-8)/(x-1) - 8} / [(-7x - 8)/(x-1) + 7] =
[(-7x - 8 - 8(x-1)) / (x-1)] / [(-7x - 8 + 7(x-1)) / (x-1)] = (-15x) / (-15) = x.
g(f(x)) = [-7*(x-8)/(x+7) - 8] / [(x-8)/(x+7) - 1] =
[(-7x + 56 -8*(x+7)) / (x+7)] / [(x - 8 - (x + 7)) / (x+7)] = (-15x) / (-15) = x.
So since f(g(x)) = g(f(x)) = x we can conclude that f and g are inverses.
Answer:
1. 3.82 miles
i dont have 2
3. 31
Step-by-step explanation:
Add the two angles and set them equal to 180, them solve for x
Answer
n-7
Step-by-step explanation:
it represents 7 less than n because you can subtract less than n because 7 is smaller
The slope is found by rise over run so it’s 8/4 and that equals 2 so it’s 2x and the second number is the y intercept which is .5 so the overall answer is
y= 2x + 0.5
