Answer:
Step-by-step explanation:
we see that y = -3x-3
substitute that into the other equation to get
-3x-3 = 2x+7
-5x = 10
x = -2
so, y = -3(-2)-3 = 3
check to make sure (-2,3) solves both equations.
Answer:
16
Step-by-step explanation:
2 x 8 is just another way of saying what would 8 + 8 be
for example, 5x5 would just 25 but 5+5+5+5+5 would also be 25
Hope this helps, sorry im not a good teacher:)
Your final balance would be $2,340.
I = Prt
Percent (6%) x rate (650) x time (60 months) = 2,340
6% = 0.06
0.06 x 60 x 650 = 2,340
Answer: no solutions
