I just took this question on a test and the answer was c
Hello,
a-3b=4 (1)
a-b=-2 (2)
(1)-(2)==> -2b=6
=>b=-3 and a=-2+(-3)=-5
Answer D
Proof
-5+3=-2
-5-3(-3)=4
First, divide. 532 divided by 4 equals 133. 1 is in the hundreds place, 3 is in the tens place, 3 is in the ones place
If ir means not, then irrational means not rational. Pi is and irrational number.
Y-y1=m(x-x1)
m= slope =-3
y-y1=-3(x-x1),
y1=-7, x1=5
y--7=-3(x-5)
y+7=-3(x-5) this is C
