4x - 9 = 0  \\ 4x = 9 \\ x =  \frac{9}{4}  \\ or \\ 4x + 9 = 0 \\ 4x =  - 9 \\ x =  -  \frac{9}{4}

  • Addition Property of Equality

<u>Algebra I</u>

  • Terms/Coefficients
  • Coordinates (x, y)
  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

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

6x - 5y = 15

x = y + 3

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

<em>Substitution</em>

  1. Substitute in <em>x</em>:                                                                                                  6(y + 3) - 5y = 15
  2. Distribute 6:                                                                                                    6y + 18 - 5y = 15
  3. Combine like terms:                                                                                        y + 18 = 15
  4. [Subtraction Property of Equality] Subtract 18 on both sides:                     y = -3

<u>Step 3: Solve for </u><em><u>x</u></em>

  1. Define original equation:                                                                               x = y + 3
  2. Substitute in <em>y</em>:                                                                                                   x = -3 + 3
  3. Add:                                                                                                                   x = 0

Which one of the following is an irrational number?
kondaur [170]

Answer:

sqrt(10)

Step-by-step explanation:

Since the second number ends and does not continue it wouldn't be the second one, and since the third is able to be predicted it wouldn't be the thrid one either and since the fourth one is 7 and is a whole number the only answer choice possible would be the first one.
