Answer:
you divide -8y by both sides and you would so that means that y=-2.

What is a Proof?
A series of steps, with justifications, that verifies a theorem or relationship exists
Types of Proofs
Two-column Proofs a table with two columns; the first column is the mathematical statement, and the second column is the justification
Paragraph Proofs a type of proof that explains the rationale for each step using complete sentences in paragraph form
Flow Chart Proofs a diagram that contains the steps of the proof and the justification for each one

Answer:
1733.28
Step-by-step explanation:
we want to find the surface area of the cylinder
We are given:
diameter = 12in
height = 40in
formula to find surface area of a cylinder: SA = 2πr^2 + 2πrh (where h = height and r = radius)
in order to find the SA of a cylinder we need to know the radius
we are given that the diameter is 12
we can acquire the measure of the radius by dividing the diameter by 2 ( this is because the radius is equal to half of the diameter )
so r = 12/2 = 6
now to find the surface area,
we simply plug in the values of the radius and height into the SA of a cylinder formula
SA = 2πr^2 + 2πrh
r = 6
h = 40
( note it says use 3.14 for π )
substitute values
SA = 2(3.14)(6)^2 + 2(3.14)(6)(40)
if you plug this into a calculator you get that the surface area is 1,733.28
The answer to the question mentioned above is "the mean" such as the whole sentence will become "The horizontal value at which the highest point of a variable's normal curve is also the MEAN of the variable". This is the answer.
