25 pounds would be a better deal
For example:
x+2y=7
6x+7y=2
__________
x=7-2y *
6*(7-2y)+7y=2 **
__________
x=7-2y
42-12y+7y=2
__________
x=7-2y
-5y=-40
__________
x=7-2y
y=8
x=-9
The slope is 2, because you subtract the points 3,17 from 7,25 to get 8/4/ Simplify that into 2.
2/3(2/8 + 4/8) = 2/3(1/4 + 1/2)
2/3(3/4) = 1/2
Answer: x² + 4x + 3
<u>Step-by-step explanation:</u>
f(x) = x² + 3x + 2
+ <u>g(x) = x + 1 </u>
(f+g)(x) = x² + 4x + 3
Note: This answer is based on f(x) having an x² (since the squared is missing from your question).
