Answer:
-1 :) you can count the number of spaces, divide by 2, and count to the middle by that ammount ;)
Distribute the x3 to each number. The coefficient stays the same but add exponent (3) onto each x. Final answer is: x to the seventh power plus 8X to the sixth power plus 2X to the fifth power +18 X to the fourth power +9x the third power
Step-by-step explanation:
(A) To find inverse of f(x) = y = 1 / x - 3 :
<u>Transform in terms of x</u>
y = 1 / x - 3
x - 3 = 1 / y
x = 3 + 1 / y
<u>Exchange x with y</u> :

Therefore, g(x) is not inverse of f(x) and vice versa.
(B)
Domain of f(x) = R - {3}
Domain of g(x) = R - {0}
d=rt
divide by r on both sides
d/r = t
300/60 =t
5=t
t=5 hours
d=rt
d/t =r
250/4.5 =r
55.5555555=r
55 5/9 miles per hour
