Answer:
30
Step-by-step explanation:
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
Answer:
$252.5
Step-by-step explanation:
45(4.5)+50
202.5+50
=252.5
If interest is 5 percent then you add 5 for every 100 so
6x5=30
then you add 30 to 600 so your answer is 630
