Answer:
the correct answer is b.
Step-by-step explanation:
it is b because if you plug in -7, two of the x-values will have -7 making the x-values the same and in order to be a function all x-values have to be different.
Answer:
Property of equality division
Step-by-step explanation:
Given
c = d
b ≠ 0 then c∕b = d∕b
Required
State the property used
From list of options a through d, only option A best fits the description.
This is so because property of equality division is such that
given two variables c and d where c = d

Provided that b ≠ 0
Take for instance;
b = 2; c = 8 and d = 8;
This implies that


Divide both sides by 2 (assumed value of b)


Correct Answer: Option AThe next step in simplification will be to convert the squared term so that it no longer contains a square.
So, we are to simplify the term

Using the half-angle identity we can write:

Using this value, the equation becomes:
Therefore, option A is the correct answer.
Dik butter lol this is fun I am getting points for these answers
