What is the domain and range

Step-by-step explanation:

well, domain is the input of a function

example

f(x) =2x+5

if the domain (x) = 2

so:

f(x) =2(2) +5

f(x) = 9

range is the output whish is :

f(x) = 9

ok then what happened.

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°
