Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtract Property of Equality

Step-by-step explanation:

<u>Step 1: Define</u>

8 = a - 2

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

  1. Add 2 on both sides:                    10 = a
  2. Rewrite:                                          a = 10

<u>Step 3: Check</u>

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

  1. Substitute in <em>a</em>:                    8 = 10 - 2
  2. Subtract:                              8 = 8

Here we see that 8 does indeed equal 8.

∴ a = 10 is the solution to the equation.

Write parametric equations of the line y=4x-5
Rasek [7]

Answer:

A set of parametric equations for the line y = 4x - 5 is;

x = t

y = 4t - 5

Step-by-step explanation:

To find a set of parametric equations for the line y = 4x - 5;

We can assign either variable x or y equal to the parameter t, in this case we can easily let x = t

We then substitute x = t in the original equation;

y = 4t - 5

Therefore, a set of parametric equations for the line y = 4x - 5 is;

x = t

y = 4t - 5

Solve for p.<br><br> 2(p + 1) = 18
n200080 [17]

Answer:

p = 8

Step-by-step explanation:

Subtract 18 from behind the equal sign to cancel it out. This leaves you with 2(p+1)- 18= 0.

Next you'll need to pull out the terms to work with the beginning of the problem. 2(p+1)- 18= 0 would turn into 2p - 16  = 2(p - 8).

This would leave you with 2= 0, but that's not true so continue on to the variable.

So p - 8= 0 making the answer p = 8

A convenience store sells a coffee mug that comes
madreJ [45]

Answer:

The cost of the mug is of $6.50.

Step-by-step explanation:

The cost of the mug and r refills is given by the following equation:

C(r) = 2.3r + 6.5

Cost of the mug:

The cost of the mug is found when no refills are bought, that is, C when r = 0, which is C(0)

C(0) = 2.3*0 + 6.5 = 6.5

The cost of the mug is of $6.50.
