Answer:

Domain: 
Step-by-step explanation:
Given

Required
Determine f(x) and its domain
To determine f(x), we replace 5x with x in f(5x)
So, we have:


Take LCM



To get the domain, we set the denominator as



Answer:
Let d = the one-way trip
Write a time equation: time = dist/speed
time out + time back = 4.5 hrs
d/80 + d/100 = 4.5
Multiply by 400 to clear the denominators
400*d/80 + 400*d/100 = 400(4.5)
Cancel the denominators
5d + 4d = 1800
d = 1800/9
d = 200 miles max distance
Answer:
the brackets signify to multiply both the numbers
3×3=9 not 3z
hope this helps you
The answer is <span>62 <span>percent. hope thats right.</span></span>
If you divide both by 11, you get 7/9. 7/9 is the fraction in simplest form.
