Equality Properties

Step-by-step explanation:

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

6x + 2 = 2(x + 4) - 2

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

  1. Distribute 2:                              6x + 2 = 2x + 8 - 2
  2. Combine like terms:                 6x + 2 = 2x + 6
  3. Subtract 2x on both sides:       4x + 2 = 6
  4. Subtract 2 on both sides;        4x = 4
  5. Divide 4 on both sides:            x = 1

<u>Step 3: Check</u>

<em>Plug in x into the original equation to verify it's a solution.</em>

  1. Substitute in <em>x</em>:                    6(1) + 2 = 2(1 + 4) - 2
  2. Multiply:                               6 + 2 = 2(1 + 4) - 2
  3. Add:                                     8 = 2(5) - 2
  4. Multiply:                               8 = 10 - 2
  5. Subtract:                              8 = 8

Here we see that 8 does indeed equal 8.

∴ x = 1 is the solution to the equation.

3x+4+8x-28=180 what x
Paraphin [41]
The equation simplified (combine like terms) would be 11x+(-24) =180.
Since adding a negative is the same as subtracting a positive, you could also write it as this: 11x-24=180. Next step is isolate the variable, so to do that you need to add 24 to both sides of the equation: 11x-24+24=180+24. This is the same as 11x=204. Now to get only one of the variable, you need to divide both sides by 11. x=18.54 repeating or x=18 6/11. Hope this helped!

The formula for the volume of a sphere is a power function:
soldier1979 [14.2K]

Answer:

r≥0

V(r) ≥0

Step-by-step explanation:

V(r) = 4/3 * Pi* r^3

The domain is the input values for r

The radius cannot be less than 0  but can be any number bigger than 0

What is the domain of the function in this situation?

r≥0

The range is the output values for the function or the volume

The volume must be greater than or equal to zero

V(r) ≥0
