Answer: 2(y + 6)(-y + 6)
Step-by-step explanation: Factor 72 - 2y^2
-2y^2 + 72
= 2(y + 6)(-y + 6)
So, i would use the add the two equation method, so add those to get:
2e=-4
e=-2
then plug in e to get d, so d+-2=1
d=3
plug into the other one to make sure
-3+-2=-5
so it would be (3,-2)
You could do :
Johnny was financing a limited editions Xbox One S. The price was $420 and he put down 40%. How much is left to be financed?
dp=420(40/100)=16800/100=168
then you would subtract 420-168 which would give you 252
;) good luck !!
Answer:
The answer to your question is:
x = -10; y = 8
Step-by-step explanation:
Solve equations by elimination method
2x + 3y = 4 (1)
x + 2y = 6 (2)
Multiply 2 by -2
2x + 3y = 4
-2x - 4y = -12
-y = -8
y = 8
Substitute y in (2)
x + 2(8) = 6
x = 6 - 16
x = -10
