Find the value of s(t(-2)):
s(x)= - 3x-2
t(x)=5x-4

s(t(-2)) is 40
Explanation: first let’s find figure out t(-2) first before we move on to the next one

t(x) = 5x-4
t(-2)= 5(-2)-4= -14

Now that we know t(-2) = -14
Then let’s find s(x) where x is -14

s(x)= -3x-2
s(-14)= -3(-14)-2= 42-2=40

And s(t(-2)) = 40
