Answer:y=7x+8
Step-by-step explanation:
Since the function is y = 3x, take any value of x and multiply it to get y.
If the y-coordinate is not 3 times the x-coordinate, it is not on the graph.
0 * 3 = 0, so (0, 0) is on the graph.
5 * 3 = 15, so (5, 15) is on the graph.
9 * 3 = 27, not 3, so (9, 3) is not on the graph.
7 * 3 = 21, so (7, 21) is on the graph.
I hope this helps!!

Answer:
The time required is 15.97 second.
Step-by-step explanation:
Consider the provided information.
A skywalk is 90 feet beyond the canyon's edge and is 4080 ft above the canyon floor.
First find the distance between skywalk and canyon floor by using Pythagorean theorem.
Distance between skywalk and canyon's edge = ![\sqrt{4080^2+90^2}](https://tex.z-dn.net/?f=%5Csqrt%7B4080%5E2%2B90%5E2%7D)
Distance between skywalk and canyon's edge = ![4080.99](https://tex.z-dn.net/?f=4080.99)
Substitute h = 4080.99 in the provided formula.
![4080.99=16t^2](https://tex.z-dn.net/?f=4080.99%3D16t%5E2)
![t^2=255.062](https://tex.z-dn.net/?f=t%5E2%3D255.062)
![t=15.97](https://tex.z-dn.net/?f=t%3D15.97)
Hence, the time required is 15.97 second.
O.38 :)
