Answer:
Part A - 
Part B - 
Step-by-step explanation:
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.
You would start with the equation:Let m=number of miles
49.98+0.12m=35.98+0.17m
Then solve for m
You would then get
49.98+0.12m=35.98+0.17m
-0.12m -0.12m
49.98=35.98+0.05m
-35.98 -35.98
14 = 0.05m
---- --------
0.05 0.05
280=m
Answer:
<h2>x + y - 2 = 0</h2>
Step-by-step explanation:
The slope-intercept form of an equation of a line:
m - slope
b - y-intercept.
Put the given y-intercept b = 2 and the coordinates of the point (1, 1) to the equation:
<em>subtract 2 from both sides</em>
The equation of a line:
The general form of an equation of a line:
Convert:
<em>add x to both sides</em>
<em>subtract 2 from both sides</em>
