  • Left to Right

<u>Algebra I</u>

  • Equality Properties
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

y = 3x - 3

y = -4x + 4

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

<em>Substitution</em>

  1. Substitute in <em>y</em>:                    3x - 3 = -4x + 4
  2. Isolate <em>x</em> terms:                    7x - 3 = 4
  3. Isolate <em>x</em> term:                     7x = 7
  4. Isolate <em>x</em>:                              x = 1

Here we see that our x-value would equal 1.

∴ (-3, 0) is NOT a solution to the systems.

Value of the expression will be 7

<u><em>Explanation</em></u>

Given value of the variables are : p= \frac{1}{2} and q=7

Given expression: 8p+3q-18

So, <u>plugging the values</u> of p and q into the above expression, we will get...

8p+3q-18\\ \\ = 8(\frac{1}{2})+3(7)-18\\ \\ =4 + 21-18\\ \\ =25-18\\ \\ =7

So, the value of the expression will be 7.

Is the product of -5 +x and x+4 equal to the product of 5+x and x-4? Explain your answer.
beks73 [17]

Let's find out!

-5 + x * x + 4.

-5 + x^2 + 4.

-5 + 4 + x^2.

-1 + x^2.

5 + x * x - 4.

5 + x^2 - 4.

5 - 4 + x^2.

1 + x^2

So, they are NOT the same, because one of the "1"'s are negative, and the other is positive.

NeTakaya

To be a function for every identical x value it has to have a different Y value. If the set has two identical X values but they have different Y values it can't be a function.

The set that is a function is:

{(1, 2); (2, 3); (3, 4); (4, 5)}
