PLEASE HELP ME PLS ITS MATH

Ganezh [65]

Answer:

Step-by-step explanation:

We know that

$h(t)=-16t^2+1296$

The balls hits the ground when h(t)=0, so

$-16t^2 + 1296=0 \\ \\ t^2 - 81=0 \\ \\ t^2 = 81 \\ \\ t=9$

Note I only considered the positive case because time must be positive.

Which expression will you generate if you combine the like terms in 5x + 6x + y + y + 3y + 4 + 6 + 2?

Anika [276]

Answer:

5x and 6x both have the letter x. Let's combine them! 5x+6x = 11x

y, y, and 3y all have the letter y. You can imagine y to be 1y, they're the same.

1y + 1y + 3y = 5y

4, 6, and 2 don't have any letters. 4 + 6 + 2 = 12

Now you have to put all the final terms together to get: 11x + 5y +12

What are the solutions to the equation |x – 10| – 4 = 2x?

Yuliya22 [10]

|x – 10| – 4 = 2x

x - 10 - 4 = 2x

x - 14 = 2x

x - 2x = 14

-x = 14

x = -14
