Answer:
A. 
B. 
Step-by-step explanation:
Consider the equation

A. This equation has no solutions when the coefficients at x are the same and the free coefficients are not the same.
First, use distributive property:

So, the equation is

This equation has no solutions when

B. The equation has infinitely many solutions when the coefficients at x are the same and the free coefficients are the same too.
So, the equation

has infinitely many solutions when

In other cases, the equation has a unique solution
Answer:
77.75%
Step-by-step explanation:
We just have to find the sums of the product of Joey's averages and their contribution to the total grade.
Test: 0.45 * 0.8 = 0.36 = 36%
Quizzes: 0.3 * 0.85 = 0.255 = 25.5%
Homework: 0.25 * 0.65 = 0.1625 = 16.25%
Total: 36% + 25.5% + 16.25% = 77.75%

Step-by-step explanation:
The dilation rule is 0.75(x,y)= (0.75x, 0.75y)
K (-4,4)----------( 0.75*-4,0.75*4)-------K' (-3,3)
L (2,4)-----------(0.75*2,0.75*4)---------L' (1.5,3)
M (-2,2)----------(0.75*-2,0.75*2)--------M' (-1.5,1.5)
