Okay, so as you know, the question starts off as this:

9x^3 + 2x^2 -5x +4 -(5x^3 -7x +4)
Distribute the negative:
9x^3 + 2x^2 -5x +4 -5x^3 +7x -4
Combine like terms:
9x^3 -5x^3 +2x^2 -5x +7x +4 -4
4x^3 +2x^2 +2x

You can either end it there or
Divide by x:
4x^2 +2x +2

Is a persons age a function of his or her height?
Igoryamba

Answer:

c. No, for each height, there are people of different ages.

Step-by-step explanation:

We say that y is a function of x when there is a relationship between x and y. For example, the distance you run on a single day and your average speed.

However

There is no relationship between age and height. For example, we may both be the same age and have very different heights.

So the correct answer is:

c. No, for each height, there are people of different ages.

Which if the filleing equations correctly represents solving q=60-4p for p.
marusya05 [52]

Since no equations were provided, the solution of the equation will depend on the values of p.

<h3>What is the solution of an equation?</h3>

The solution of an equation is the value that makes that equation true.

Given the equation q = 60 - 4p

The solution of the equation will depend on the value of p

For example; if p = 1

q = 60 - 4(1)

q = 56

Therefore, the solution of the equation will depend on the values of p.
