-4, -1/5, 1/5, and 1 1/5?
Answer:
6x^2 + -10
Step-by-step explanation:
Hi there! I'm glad I was able to help you answer this polynomial expression!
All we're really doing to solve is combine like terms.
(5x^2+2) - (-4x^2+7) + (-3x^2-5) = _____________
5x^2 + 2 + 4x^2 + -7 + -3x^2 + -5
(5x^2 + 4x^2 + -3x^2) + (2 + -7 + -5)
6x^2 + -10
The terms that have x^2 at the end are in bold letters so you know what we're combining them - the other numbers are the separate like terms.
Simplified, our answer is 6x^2 + -10.
I hope this helped you! Leave a comment below if you have any further questions! :)
Answer:
Solution (4,3)
Step-by-step explanation:
2x-7y= -13
<u>(8x-7y=11)x-1</u>
2x-7y= -13
-8x +7y= -11

x= 4
__________
2x-7y= -13
2(4)-7y=-13
8-7y= -13
subtract 8 from both sides

divide by -7
y= 3
hope it helps..
have a great day!!
