Which equation can pair with x – y = –2 to create a consistent and dependent system? 6x + 2y = 15
–3x + 3y = 6
–8x – 3y = 2
4x – 4y = 6

Fractions can be added and subtracted only if they're fractions. a. like b. proper c. improper d. unlike

Average acceleration: i have no idea how to do this.

1. a parachutist is 800 feet above the ground when she opens her parachute. she then falls at a constant rate of 5 feet per second. select the equation that represents this situation. h = -800t + 5 y = -5x + 800 h = 5t - 800 y = 800x + 5 i need
