75/3=25 miles per hour
That's your answer.
8x^2 = 96x
8x^2 - 96x = 0
8x(x - 12) = 0
8x = 0....x = 0
x - 12 = 0
x = 12
ur number is 12
Answer:


Step-by-step explanation:
The functions, missing from the question are:


Required
Determine the domain
To get the domain, means we want to get the possible values of x.
(a)

Equate 3 - x to 0

Solve for x


From the calculated value of x above;
When x exceeds 3; f(x) = undefined
So: the domain is:

(b)

Equate 3x to 0

Solve for x

From the calculated value of x above;
When x falls below 0; f(x) = undefined
So: the domain is:

First you multiply 145 by 01.75 to get how much you add to the total. You add 253.75 to 145 and get 398.75 as the answer
