Answer:
A. -24
Step-by-step explanation:
we know that
A relationship between two variables, x, and y, represent a directly or proportional variation if it can be expressed in the form
or 
In this problem we have
For x=-3, y=12
Find the value of the constant of proportionality k

substitute the given values

so
The linear equation is equal to

what is the value of y when x=6?
substitute the value of x in the linear equation and solve for y

The sum of polynomials involves adding the polynomials
The other polynomial is 
The sum of the polynomials is given as:

One of the polynomials is given as:

Represent the other polynomial with Q.
So, we have:

Substitute the expressions for P and Sum

Make Q the subject

Evaluate like terms

Hence, the other polynomial is

Answer:
To see all the points that lie on the equation
h(x) = 3*x^2
We use a graphing calculator, to plot the function h(x)
Please see attached image for more information.
We can see in red all the points that lie on the function. There are an infinite number of points in it.
Answer:
Corresponding Angles Theorem
x = -5
Step-by-step explanation:
Since they are corresponding angles, they are equal to each other.
x + 105 = 100
x = -5
