HELP PLS Question 1 of 1
A daredevil jumps off the CN Tower and falls freely for several seconds before
releasing his parachute. His height, h, in meters, t seconds after jumping can be
modelled by: h = -6t2 - 50t + 200 before he released his parachute, and h =
- 3t + 100 after he released his parachute.
How long after jumping did the daredevil release his parachute? At what height?

To solve the system of equations below, grace isolated the variable y in the first equation and then substituted into the second equation. what was the resulting equation? 3y=12x x^2/4+y^2/9=1

Zroms according to the synthetic division below, which of the following statements are true? check all that apply. 352 -2 6 -12 12 2 4 0 i a. (x-3) is a factor of 2x2 - 2x - 12. b. the number 3 is a root of f(x) = 2x2 - 2x - 12. c. (2x2 - 2x - 12) = (x + 3) = (2x + 4) d. (2x2 - 2x-12) - (x-3) = (2x + 4) e. (x+3) is a factor of 2x2 - 2x - 12. o f. the number -3 is a root of fx) = 2x2 - 2x - 12. previous

Using elimination, what is -4x+2y=-12 4x+8y=-24
