1 answer:
You can reword the two equations as:
-5x-y=15 (Divide original value by 3)
-2x+6y=6
Then use elimination to find x:
-30x-6y=90 (Multiply by 6 to get y values to be same to cancel out)
-2x+6y=6
You're left with:
-32x=96. Which can then be solved to find x which is -3.
Then plug back in
-2x+6y=6
Now to: -2(-3)+6y=6.
Which reduces to 6+6y=6. So y=0.
To graph them, just reword the equations (yes once again) so that y is in front.
y=-5x-15 and y=(1/3)x+1

is it 32
Step-by-step explanation:
I hope this helps you
Volume =pi.r^2.h
Volume =3,14.8^2.10
Volume =31,4.64
Volume =200,96
11=27
12=27
13=4
14=16
15=24
16=?
sorry I couldn't solve them all, hope that helped :D
I think the correct answer would be C. hope this helped !
8x + 6=4x + 38
4x = 32
x = 8
<B = 4x + 38 = 4(8) + 38 = 70
