Identify the independent and dependent variable of the following graph. indicate whether the graph rises, falls, or is constant

a. independent variable: interest level, dependent variable: performance
graph falls and then steadily rises
b. independent variable: interest level, dependent variable: performance
graph starts low, rises until it reaches a maximum point and then falls
c. independent variable: performance, dependent variable: interest level
graph starts low, rises until it reaches a maximum point and then falls
d. independent variable: performance, dependent variable: interest level
graph falls and then steadily rises

b. Independent Variable: interest level, Dependent Variable: performance ; Graph starts low, rises until it reaches a maximum point and then falls

Step-by-step explanation:

The independent variable goes along the x-axis.  In this graph, that is interest level.

The dependent variable goes along the y-axis.  In this graph, that is performance.

From left to right, the graph starts low and increases.  It reaches a maximum point and then falls again.

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)

step- i d k and i d c : )

you: : 0
