The answer to find the vaules is A=3x
Answer:
The coordinates of EF are E(5,-4) and F(1,-4).
The line segment EF is in QIV
Step-by-step explanation:
The line segment AB has vertices at: A(-4,5) and B(-4,1).
We apply the rule 
to reflect AB in the y-axis to obtain CD.
We apply the rule 
to rotate CD 90 degrees clockwise about the origin to obtain EF.
The coordinates of EF are E(5,-4) and F(1,-4).

Answer:
It would be C
Step-by-step explanation:
This triangle has two equal sides and one side that is not equal to the other two, so it is an isosceles triangle.
If the smaller number is x, then the larger number has to be 20 - x in order for the arithmetic mean to be 10, as their sum must be 20.
If the geometric mean is 8 the product of the numbers has to be 64 and so the larger number is 64/x
Solving 64/x = 20 - x gives the quadratic x^2 -20x +64 = 0 so x = 4 or 16.
The two numbers are 4 and 16.
The second one because there is all the inputs are different. There is one input for every output.
