Answer:
A. Coefficient
Step-by-step explanation:
The coefficient comes right before the variable, which is the unknown number. The other number that might be there is the constant, and that number does not have a variable with it.
Expanding the left side of the equation, it is found that since <u>both sides are equal</u>, yes, it is an identity.
An equality represents an identity if <u>both sides are equal</u>.
In this problem:

Expanding the left side:

Answer for #9 : 24,720
Answer for #10 : 145
Answer: A
Step-by-step explanation:
The line and dots are closed circle, so B and D would not be the answer.
The line have passed through the point (-6,4) and (0,2); we uses to find the slope.
slope = m = (y2 - y1)/(x2 - x1) = (2 - 4)/(0 - (-6)) = -2 / 6 = -1/3
we plug in slope to the linear equation in form of y = mx + b, where m is the slope, and b is the y- intercept.
y = -1/3x + 2
So the answer is A.
