Solve the system of equations below.
2x + 4y = 10
2x + 4y = -10

a. x = 3, y = 1
b. x = 6, y = -4
c. no solution
d. infinitely many solutions

In the xy-plane, if the parabola with equation passes through the point (-1, -1), which of the following must be true?

Ireally need subtract and simplify.(-y^2 – 4y - 8) – (-4y^2 – 6y + 3)show your work, ! i will mark you brainliest but you have to show your work.

(03.03 mc) choose the graph below that correctly represents the equation 2x + 4y = 24. (5 points) select one: a. line through the points 0 comma 6 and 12 comma 0 b. line through the points 0 comma negative 6 and 12 comma 0 c. line through the points 0 comma negative 12 and 6 comma 0 d. line through the points 0 comma 12 and 6 comma 0
