-10a and -8a are like terms, but -3ab is not equivalent. With the two a terms, we have:
-10a-8a
a(-10-8)
-18a
We then add in the other term (-3ab) for a final result of -3ab+-18a. This can be factored alternatively as -3a(b+6).
(0,10)
(1,1)
I am pretty sure these are correct. But you can always dubble Check if you have a graphic calculator. If so, all you have to do is press the y= button which should be located around the top left corner. Then you out in this equation, and then press 2nd (the only blue button)graph and it will give you all the points, but you would only pick the point that can reach on you graph. Hope this helped
Step-by-step explanation:
1/8+1/2make both denominators 8
in 1/2 multiply both the numerator and the denominator by 4to get 4/8
1/8 + 4/8=5/8
