A fraction is in it's simplest form if both of the numerator and denominator are not divisible by a number.
Answer:
120
Step-by-step explanation:
.
Plug in the information given:
.
Now we want to solve this equation for Run.
If you don't like Run as a variable, let's just use x in it's place:

Cross multiply:

Simplify both sides:

The run is 120.
Let's check our work.
.
So if our rise is 6 and our run is 120.
Does 6/120 reduce to 1/20?
6 and 120 do have a common factor of 6.
So if you divide top and bottom of 6/120 by 6 you do get 1/20.
Answer: y-12
Step-by-step explanation:
-3(y+4)+4y
first distribute teh -3 to the y and the 4, so you get -3y and -12. Then combine like terms. -3y-12+4y, add the -3y and 4y, you get y. So the answer is y-12.
To find f(g(x)), we'll treat g(x) as if it were the x in f(x).
g(x) = x + 3
f(g(x) = (x+3)^2 - 1
