Answer:
"The percentage change of a ratio of two variables is approximately the percentage change in the numerator <u>minus</u> the percentage change in the denominator."
Step-by-step explanation:
The percent change in a number is determined by dividing the difference between the new number and original number by the original number and multiplying the result by 100.
Suppose the original ratio of two numbers is:
.
And the new ratio is: 
The percent change is:

Thus, the complete statement is:
"The percentage change of a ratio of two variables is approximately the percentage change in the numerator <u>minus</u> the percentage change in the denominator."
Answer:
A <em> </em><em>and</em><em> </em><em>E</em><em> </em><em>is</em><em> </em><em>true</em><em>. </em><em>BCD</em><em> </em><em>is</em><em> </em><em>False</em>
Step-by-step explanation:
Let convert this into slope intercept form



So now let answer these questions,
A is TRUE the slope is the number in front of the x value. It is 20 so a is true.
B is False, Using (0, 500) The equation is wrong

C is false, we have a positive slope so it shifts upward from left to right.
D is false
the slope isn't 200.
E Is true the y intercept is when the x value is 0, what is the y value so plug it in we get

It equal 50.
X-7=8
Add 7 to both sides so you can isolate the variable
x=15
