8 0

Answer:

The number is 2,5

Step-by-step explanation: For solve this problem we have to made a polinomial function as follows:

We know that is a half number that means X/2, the next step we have to decrese by 8, $\frac{X}{2}$ -8, finally the result is (-3).

$\frac{x}{2}$ -8=-3 ⇒ $\frac{x}{2}$ =-3+8

$\frac{x}{2}$ =5 ⇒ x= $\frac{5}{2}$ or x=2.5

Using the slope formula, find the slope of the line through the points (0,0) and (4,8).

Answer:

$m = 2$

Step-by-step explanation:

<u>Using mental math to find the slope of the line:</u>

If you think about the formula, then you set up the points in your head, you will notice that the first point is on top of the second point. And that way makes it easy to simplify. All you would need to do is subtract down in your head: For example:

(0, 0)

(4, 8)

As you can see, the first point is on top of the other, and that way you can just subtract from bottom to top. If you do it that way, it is set up (Remember, you would do this all in your head)
