Nancy created a graph to predict the pay she will take home after taxes are taken from her income. using the information on the graph, what is the constant of proportionality?
a. 0.48
b.0.6
c.0.8
d.1.25

Option C. 0.8

Step-by-step explanation:

Nancy created a graph to predict the pay she will take home from her income.

The constant of proportionality will be =

For the income of $80 constant of proportionality =

and for the income of $130 constant of proportionality =

Therefore, option C. constant of proportionality = 0.8 is the answer.

i think it is x = 1.2

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°
