Answer:
D
Step-by-step explanation:
12. if you take half of 12, 6, then you add 5, you get 11.
Set up a system of equations:
2x+3y=6
x-3y=9
You can solve this with elimination by adding the two equations together:
3x+0y = 15
3x=15
x=5
Then, plug this value back into either of the original equations to find the y value:
5-3y=9
-3y=4
y= -4/3
The point of intersection is (5,-4/3)
Note: two negatives multiplied together = one positive answer
one negative & one positive multiplied together = one negative answer
Multiply -8 and -3 together
-8(-3) = 24
24(-2) = -48
-48(4) = -192
D) -192 is your answer
hope this helps
