Which table best represents the system of equations below. y=x-4 y=(2x-17)
vekshin1

Answer:

To make a table u need to have coordinates, (x, y).

Solve for them using substitution:

y = x - 4 ↔ x = y + 4

y = (2x - 17)

PLUG IN TO y = (2x - 17).

y = (2(y+4) - 17)

Solve for y:

y = 2y + 8 - 17

y = 2y - 9

-1y = -9

y = 9

Solve for x:

x = (9) + 4

x = 13

Keep solving for x and y to have your coordinates for your table.

he ate 2/3 of the broccoli part......2/3 of 1/2 = 2/3 * 1/2 = 2/6 = 1/3
he ate 1/4 of the mushroom part....1/4 of 1/2 = 1/4 * 1/2 = 1/8

so he ate 1/3 + 1/8 = 8/24 + 3/24 = 11/24 <==
