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.

the circle graph is not a function.

step-by-step explanation:

the graph of the circle is not a function.

because for a graph to be a function, each value of x must give one value of y

in the circle, the values of x for -2< x< 2 each give 2 values of y.

hence this is not a function.

x > 1.3

step by step:

8.5−0.9x> 9.8−1.9x

step 1: simplify both sides of the inequality.

−0.9x+8.5> −1.9x+9.8

step 2: add 1.9x to both sides.

−0.9x+8.5+1.9x> −1.9x+9.8+1.9x

1x+8.5> 9.8

step 3: subtract 8.5 from both sides.

1x+8.5−8.5> 9.8−8.5

1x> 1.3

step 4: divide both sides by 1.

1x/1 > 1.3/1
