The functions r and s are defined as follows. r(x)=-5x-5 s(x)=3x+1 find the value of s(r(-

46

Step 1 is to compute the value of r(-4)

r(x) = -5x-5

r(-4) = -5(-4)-5 ... replace every x with -4

r(-4) = 20-5

r(-4) = 15

Now we can do replacements. We can replace the "r(-4)" with 15 because of the last equation above.

So we go from s(r(-4)) to s(15)

Plug x = 15 into the s function

s(x) = 3x+1

s(15) = 3*15+1

s(15) = 45+1

s(15) = 46

In the end,

s(r(-4)) = 46

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
