Which statement explains why the point (-2, 2) is the solution to the system of linear equations shown below?
a: It lies on the graph of only one of the equations
B: It lies on the second quadrant of the coordinate plane
C: It is the only point that satisfies both equation simultaneously.
D: It is the one of many points that satisfies both equations simultaneously

C)

Step-by-step explanation:

if you think about the equations as linear functions, you can imagine that if they do intersect, it must be on only one point (since two straight lines cant intercept at more than one point, unless they are the same line)

therefore the point has to be the one and only intercept- satisfiing both linear equations

$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)
