Answer:
a and b are parallel
Step-by-step explanation:
corresponding angles converse
2c -7 >= 9
2c >= 16
c >= 8
5d + 7 <= 32
5d <= 25
d <= 5
normal arthematic except diving over -1 or flipping (taking inverse -1) flips the operator
Answer:
When t = 4
Step-by-step explanation:
The phone will hit the ground when h = 0.
![16t^2 + 32t + 384 =0 \\ \\ t^2 + 2t + 24=0 \\ \\ (t+6)(t-4)=0 \\ \\ t=-6, 4](https://tex.z-dn.net/?f=16t%5E2%20%2B%2032t%20%2B%20384%20%3D0%20%5C%5C%20%5C%5C%20t%5E2%20%2B%202t%20%2B%2024%3D0%20%5C%5C%20%5C%5C%20%28t%2B6%29%28t-4%29%3D0%20%5C%5C%20%5C%5C%20t%3D-6%2C%204)
However, as time cannot be negative, we know the answer is when t = 4.
All you need to do is plug -5 into the second equation and you see it is near (-5, -8). When plugged into the top, you get (-5, -27/4) which comes out to ABOUT -6.75 for the Y value. The closest is actually a tie. The first option is .8 from the first and .45 from the second leading in a total distance of 1.25. The second, which is the fellow answer, is 1.2 from the first and .05 from the second, leading to 1.25 away.
The third, which is next closest is 1.8 from the first and .55 from the second leading to a distance of over 2 from the optimal, so only the first two are answers.
