= f(x)=-2X+13 for f(10)

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

It says factor each expression completely 8y+48

Ineed to know the ordered pairs for this equation i need the answer quick because it’s a timed test
