Answer:
1.5seconds
Step-by-step explanation:
When the ball hits the ground, the height is equal to zero. So find t when H=0:
H=16t²+8t+80
0=16t²+8t+80
0=2t²+t+10
0=(2t-3)(t+2)
So (2t-3)=0, or (t+2)=0
So t=1.5 or t=-2. Time can't be negative though, so we take our answer as 1.5seconds

Answer: y = -x + 6</h3>
To get this answer, you subtract x from both sides to go from x+y = 6 to y = 6-x which rearranges to y = -x+6
Note that y = -x+6 is the same as y = -1x+6
We can compare this to y = mx+b form to see that m = -1 is the slope and b = 6 is the y intercept.
