Aditya installed solar panels for her house. When the solar panels produce more electricity than Aditya uses in a day, her net electricity use is negative. The graph below shows Aditya's net electricity use in the first week of July. The xxx-axis represents days in July, and the yyy-axis represents net electricity use in kilowatt-hours (\text{kWh}kWhstart text, k, W, h, end text). Determine if each statement about the graph is true or false. True False The highest net electricity use occurred on July 444th. The net electricity use on July 222nd is represented by (2,-1)(2,−1)left parenthesis, 2, comma, minus, 1, right parenthesis.

yes

{x = -1/2 ,   y = -1

step-by-step explanation:

solve the following system:

{2 x + y = -2

{10 x - 3 y = -2

in the first equation, look to solve for y:

{2 x + y = -2

{10 x - 3 y = -2

subtract 2 x from both sides:

{y = -2 x - 2

{10 x - 3 y = -2

substitute y = -2 x - 2 into the second equation:

{y = -2 x - 2

{10 x - 3 (-2 x - 2) = -2

10 x - 3 (-2 x - 2) = (6 x + 6) + 10 x = 16 x + 6:

{y = -2 x - 2

{16 x + 6 = -2

in the second equation, look to solve for x:

{y = -2 x - 2

{16 x + 6 = -2

subtract 6 from both sides:

{y = -2 x - 2

{16 x = -8

divide both sides by 16:

{y = -2 x - 2

{x = -1/2

substitute x = -1/2 into the first equation:

{y = -1

{x = -1/2
