which equation does the graph of the systems of equations solve?

quadratic graph opening down and quadratic graph opening up. they intersect at 0, 3 and 3, 0.

a. x2 − 2x + 3 = 2x2 − 4x − 3
b. x2 − 2x + 3 = 2x2 − 4x + 3
c. −x2 + 2x + 3 = x2 − 4x + 3
d. −x2 − 2x + 3 = x2 − 4x + 3

The answer is c

Step-by-step explanation:

Just took the test

$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)
