Suppose that the functions s and t are defined for all real numbers x as follows. s(x)=x-4
t(x) = 4x+6
Write the expressions for (s • t)(x) and (s-t)(x) and evaluate (s+t)(-1).
(s. t)(x) = 1
(s – t)(x) = 0
(s + t)(-1) = 0
?

answer: 1, 3 and 5 are correct

step-by-step explanation:

answer: (c) m∠qpo + (2x + 16)° = 180°

step-by-step explanation:

the opposite angles of a quadrilateral are supplementary.

so, ∠o + ∠q = 180°   and   ∠p + ∠r = 180°

since ∠r = 2x + 16°, we can use substitution as follows:

∠p + ∠r = 180°

∠p + (2x + 16)° = 180°
