A ball is thrown straight out at 80 feet per second from an upstairs window that's 15 feet off the ground. It turns out that its motion can be broken down into its motion in the x-direction (horizontally) and its motion in the y-direction (vertically), and that those two components can be thought of completely independently. In other words, its horizontal motion has no influence on its vertical motion, and vice versa. I've written the two component functions here: x(t) is its position in the x-direction, and y(t) is its position in the y-direction. Which of the following choices is correct? (Ignore air resistance.) NOTE: Use a reference frame that makes all positions (x and y coordinates) of the projectile positive.

Step-by-step explanation:

What is the solution to the equation -3(h+5)+2=4(h+6)-9

Answers

Answer:

h=-4

Step-by-step explanation:

The equation is -3(h+5)+2=4(h+6)-9 we need to find the value of h.

First we are going to distribute the products.

-3(h+5)+2=4(h+6)-9\n -3h-15+2=4h+24-9\n -3h-13=4h+15

We have to put the terms with letter h in the left side of the equation and the terms without h in the right side;

-3h-13=4h+15\n -3h-4h=15+13

-7h=28

Now, for the last step we have to divide both sides of the equation in (-7):

-7h=28\n ((-7)h)/((-7)) =(28)/((-7)) \n h=-4

The answer to your question is h=−4
