Answer:
y = -11x + 9
Step-by-step explanation:
m = -11
x = -1
y = 20
Plug those values into the equation to find b: y = mx + b
20 = (-11)(-1) + b
---> b = 9
Plus m = -11 and b = 9 into y = mx + b
---> y = -11x + 9
Answer:
Step-by-step explanation:
35=-5t²+10t+22
5t²-10t+13=0
disc =b²-4ac=(-10)²-4×5×13=100-260=-160<0
t is imaginary.
So ball never reaches a height of 35 m
