Answer:

5/2

Step-by-step explanation:

<u>Rise</u> = <u>5</u>

Run    2

Now, with that,  our y intercept is -6 because the line hits the y axis at -6 units. Then, we can setup our own equation for y=

and that is y=5/2 x -6

Then I have attached a graph below to certify my answer.

What is a difference of squares that has a factor of x 8? x2−4 x2−16 x2−64 x2−256
Aleksandr-060686 [28]

Answer:

  (c)  x² -64

Step-by-step explanation:

The factoring of the difference of squares is one of the special forms we use in the study of polynomials. It tells you ...

  a² -b² = (a +b)(a -b)

__

You have a factor (x +8), so a=x, b=8, and the "expanded" form is ...

  a² -b² = x² -8² = x² -64

Equality Properties

Step-by-step explanation:

<u>Step 1: Define Equation</u>

8(2x + 5) = 16x + 40

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Distribute 8:                                  16x + 40 = 16x + 40
  2. Subtract 40 on both sides:          16x = 16x
  3. Divide 16 on both sides:               x = x

Here we see that <em>x</em> does indeed equal <em>x</em>.

∴ <em>x</em> has an infinite amount of solutions.
