Step-by-step explanation:

Subtitute y in the first equation.

Now replace x in either equation to find y.

Answer:
The object will hit the ground after 10.308 seconds.
Step-by-step explanation:
h(t) = -16t² + 1700
If you graphed this function, the object would be shown hitting the ground when it crosses the x-axis, in other words, when h = 0. So, to find the answer, just set h(t) equal to 0 and solve.
-16t² + 1700 = 0 Plug this into a calculator if you have one.
t = -10.308 and t = 10.308
Since time can't be negative, your answer will be the positive value, 10.308.

This is what you have to explain:
With 5n, you are multiplying a number and a variable.
With 5 + n, you are adding a number and a variable.
