Answer:
eight away .7 can be used into 3 4 times with a sum of 2.8 and that leaves .2 which would be left out since it is not a whole .7 so C
Step-by-step explanation:
S(x) = 2 - x²
t(x) = 3x
s(t(x)) = st(x)
s(t(x)) :
s(3x)
So in s(x) = 2 - x², to solve for s(3x) we replace x with 3x
s(x) = 2 - x²
s(3x) = 2 - (3x)²
= 2 - 9x²
st(x) = 2 - 9x²
st(-7) = 2 - 9*(-7)(-7)
= 2 - 9*49 = 2 - 441 = -439
st(-7) = -439
