The correct answers are
A and C.
Please see the attached picture for the organized work.
Answer:
25
Step-by-step explanation:
the question basically translates to
160% x n =40
a little trick with percents I use is that the word "of" always means multiplication.
n=40/160%=25
The given system is
Given that y = y, let's combine the equations
Let's solve for x
Then, we find y
The solution is (2, -3).
The image below shows the solution graphically.
Using the slope formula the answer would be 1-(-1)/(-1)-6. The slope would be 2/-7. It would be a negative slope.
