98 ! the graph shows two lines, a and b. how many solutions does the pair of equations for lines a and b have? explain your answer. (correct answers only )

A solution for a set of equations is the number of times the two lines would cross each other.

The attached graph is two straight lines that cross each other only once, therefore there is only one solution which is located at (3,5).

step-by-step explanation:

b and c

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°
