Answer:

Homework creates a bridge between school and home. Parents rarely get to spend much time with you while you're at school. Homework allows them to keep up with what you're doing in your classes on a daily basis. But you don't have homework purely for your parents' benefit. It's good for you, too, or maybe because teachers want to see us suffer

What is the solution to the equation 2(4-3x)+5(2x-3)= 20-5X2​
Alja [10]

Answer:

7-16x=10. I'm sorry I'm not good at math but it never hurts try, right?

Step-by-step explanation:

Multiply the parentheses first which would give you

8-6x+10x-15.

Next add 6x+10x which would give you

8-16x-15.

Then subtract 8-15 which would give you

7-16x=20-5x2. Then work the problem from there.

7-16x=20-10.

7-16x=10.

The number of seconds it takes for the waste to hit the ground for the given function is: 5 seconds.

<h3>How to Evaluate a Function?</h3>

We are given the function of height to time as, h(t) = -16t² + initial height, and we have the following:

  • h(t) = 0 (height of the ground is 0)
  • t = seconds the waste takes to height the ground
  • Initial height = 400 feet

Plug in the values into the equation of the function

0 = -16t² + 400

Solve for t

0 - 400 = -16t²

-400 = -16t²

-400/-16 = t²

400/16 = t²

√(400/16) = t

20/4 = t

5 = t

t = 5

The number of seconds it takes is: 5 seconds.

Does this table represent a function? Why or why not?
Rasek [7]
By definition we have to:

 A mathematical function is a relationship that is established between two sets, through which each element of the first set is assigned a single element of the second set or none.
 The initial set or starting set is also called the domain; the final set or set of arrival, meanwhile, can be called codomain.

 For this case, the table represents a function and the function is linear because the rate of change (slope) is constant and equal to 200.
