13 (2)-2(0.5) = 26-1 = 25
Score = 25 points
All you have to do is simplify each term. And by doing so, you will get 4y^-4 + 2 - 1
y = | x -5| + |x+5|
as range of x is
-5 < x < 5
we can see if we put x = 0 we get
y = 10
we put any value of x in given range first term is always negative without absolute. and 2nd term is always positive
so
y = | x -5| + |x+5|
= -( x-5) + x + 5
= - x + 5 + x + 5
= 10
so
y = 10 where -5 < x < 5
The slope is 2 hope this helps
