Whats the answer
i am working on the same test right now
Answer: (4,8)
First you have to solve for Y in either equation. I solved for Y in the second equation and my new equation was y=12-x.
Then you plug this new equation into the equation you did not touch. It will become 3x+ (12-x)=20.
Next you solve this equation for X which would be 4.
Lastly you plug in 4 in either equation. I plugged it in the first equation and it became 3(4)+y=20
I hope this helps some :)
Answer:
25
Step-by-step explanation:
(-5)^2+10(-5)(2)+25(2)^2
=25+(-100)+100
=25
so what you have to do is multiply 3 and 2 and 3 and -14 which ends up being 6x-42x=, then do 15 times -9 and you then do 15 times -5 and that becomes -135x - (-7) then you show it like this= 6x-42x=135x-(-7) the solution would be 36x=-135 divide 36 each side and you get x= 2.28
