Answer:
See below.
Step-by-step explanation:
So we have the expression:
First, factor out the GCF.
The GCF is 2u². Thus:
And this is the simplest it can get.
So we are done :)
To find the value of r
We will follow the steps below
Usinf the equation of a slope:
slope(m) =
from the question given;
m= -3/4
x₁ = 3
y₁=4
x₂=-1
y₂=r
substituting the values into the slope formula
we can now simplify and then solve for r
cross-multiply
-3 x -4 = 4(r-4)
12 = 4(r-4)
Divide both-side of the equation by 4
3 = r - 4
add 4 to both-side of the equation
3+4 = r-4+4
7 = r
r=7
Therefore the value of r is 7
