Solve the system of equations: y = 2x
y=x2-3

A. (-1,2) and (3, 2)
B. (-2, -4) and (2, 4)
C. (-2, 1) and (2, 1)
D. (-1, -2) and (3, 6)

D. (-1, -2) and (3, 6)

Step-by-step explanation:

y = 2x

y = x² - 3

2x = x² - 3

x² -2x - 3 = 0

(x + 1)(x - 3) = 0

x = -1 or x = 3

y = -2 or y = 6

b.-4 units

all you   do is count how many times you move

the multiples of 15 are 15, 30,45, 60, 75, 90, 105, 120, 135, 150, 165, 180, 195,   210, 225, 240, 255, 270, 285, 300, 315, 330, 345, 360, 375,   390, 405, 420, 435, 450, 465, 480, 495, 510, 525, 540, 555, 570, 585, 600, 615, 630, 645, 660, 675, 690, 705, 720, and 735.

the factors of 15 are 1, 3, 5, and 15.

hope that , fam!
