Find the value of s (t (-5)):

s (x) = - 3x-2

t (x) = 5x - 4

s (t (-5)) First find t (-5), since you know x = - 5, substitute/plug in - 5 for x in t (x) = 5x - 4

t (x) = 5x - 4

t (-5) = 5 (-5) - 4

t (-5) = - 25 - 4

t (-5) = - 29

s (t (-5)) plug in - 29 for t (-5)

s (-29) = - 3 (-29) - 2 ( - times a - equals a positive)

s (-29) = 87 - 2

s (-29) = 85

Your answer is 85
