Answer:
x=-3, y=-6. (-3, -6).
Step-by-step explanation:
-9x+7y=-15
-8x+y=18
------------------
y=18-(-8x)=18+8x=8x+18
----------------------------------
-9x+7(8x+18)=-15
-9x+56x+126=-15
47x+126=-15
47x=-15-126
47x=-141
x=-141/47
x=-3
-8(-3)+y=18
24+y=18
y=18-24=-6
x=-3, y=-6.
Answer:
A reflection over the x- axis would be the correct answer.
Step-by-step explanation:
When you flip figure A over the x-axis it will land onto figure B.
Answer:
-25
Step-by-step explanation:
formula for areas of rectangles= width x height
width=x-5
height=x+5
(x-5)(x+5)= -5x+5x-25
since the 5x's cancel out each other
=-25 will be the answer
7*(x+5)*(x -5) that is your answer right there
