Answer:

A

Step-by-step explanation:

Well - 19-11 is -30

So you have to work out the equations and find which one is equal to - 30

-19 + (-11) = - 30

-11 +(19)=8

11-19 = - 8

And

19+11 =30.

So A is the equivalent.

(-19 and - 11 added together is - 30)

Answer:

  • no square roots: -1000, -8
  • one square root: 0
  • two square roots: 8, 64, 1000
  • no cube roots: <none>
  • one cube root: -1000, -8, 0, 8, 64, 1000
  • two cube roots: <none>

Step-by-step explanation:

The attached graph shows the square root relation (red) and the cube root function (blue). The function values are shown for x=0 and x=±8.

You can see that there are 2 square roots for positive numbers, one square root for 0, and 0 square roots for negative numbers. There is exactly 1 cube root for any number.

  • no square roots: -1000, -8
  • one square root: 0
  • two square roots: 8, 64, 1000
  • no cube roots: <none>
  • one cube root: -1000, -8, 0, 8, 64, 1000
  • two cube roots: <none>

<em>Additional comment</em>

We call the square root curve a "relation" because it is <em>not a function</em>. A relation that is a function will have only one y-value for each x-value. For positive x-values, there are two square roots.

Find the slope and write it in slope intercept form
Afina-wow [57]

Answer:

y= 1/2x -7

Step-by-step explanation:

Find the y-intercept. It is where the line crosses "y" which is -7

Next find the rise and the run for "x"

Rise - 1

Run - 2

Then put them in slope intercept form

y=1/2x -7
