Anita’s solution was (0, 5) and (8, 21). Which method can Anita use to determine the
reasonableness of her solution to the system of equations?

Anita can solve each equation for y, graph both equations on a coordinate plane, and

determine the intersection points.

Anita can solve each equation for y, create a table of values for each equation, and

determine

Anita can substitute the point (0, 5) into both equations and confirm that it yields a true

equation, and also substitute the point (8, 21) into both equations and confirm that it yields

a true equation.

All the answers are correct

Which statement identifying the number of cell phones Victoria must repair so her cost and sales
are the same is true?

Victoria needs to repair 15 phones because the solution shows costs and sales are equal for

approximately 14.5 and –34.5 repairs and it is not reasonable to partially repair a phone or

repair –34 phones

Victoria needs to repair 10 phones because the solution shows costs and sales are equal for

approximately 10 and –50 repairs and it is not reasonable to repair –50 phones.

Victoria needs to repair 35 phones because the solution shows costs and sales are equal for

approximately –14.5 and 34.5 repairs and it is not reasonable to partially repair a phone or

repair –14 phones.

Victoria needs to repair 50 phones because the solution shows costs and sales are equal for

approximately –10 and 50 repairs and it is not reasonable to repair –10 phones.

In the year 2002, Jordan and Alex each received $4,000. Jordan decided to put his $4,000 in a personal safe and each year add $800 to his money stash because he does not trust banks. Alex decided to invest her $4,000 in technology stocks. The value of Alex’s stocks increased according to a parabolic curve until it peaked at $48,000 in 2018. By 2022, Alex’s technology stock had fallen to a value of $34,000.
Formulate a system of equations to determine the number of years it would take for the amount Jordan has in his money stash to be equal to the value of Alex’s technology stocks. (Round to the nearest whole number.)
