<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>

y = -4x + 1

11y = x + 146

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

<em>Substitution</em>

  1. Substitute in <em>y</em>:                                                                                                   11(-4x + 1) = x + 146
  2. Distribute 11:                                                                                                     -44x + 11 = x + 146
  3. [Addition Property of Equality] Add 44x on both sides:                              11 = 45x + 146
  4. [Subtraction Property of Equality] Subtract 146 on both sides:                  -135 = 45x
  5. [Division Property of Equality] Divide 45 on both sides:                             -3 = x
  6. Rewrite/Rearrange:                                                                                             x = -3

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

  1. Define original equation:                                                                                  y = -4x + 1
  2. Substitute in <em>x</em>:                                                                                                   y = -4(-3) + 1
  3. Multiply:                                                                                                           y = 12 + 1
  4. Add:                                                                                                                      y = 13

Answer:

\sqrt[3]{4}

Step-by-step explanation:

To solve this we need to take the square root of both sides with a certain degree.

4^6 = a^{18}

We can take the root of both sides with a degree of 18.

\sqrt[18]{4^6} = \sqrt[18]{a^{18}}  \\(4^6)^{\frac{1}{18} } = a\\a = 4^{\frac{6}{18} } = 4^{\frac{1}{3} } = \sqrt[3]{4}

It's helpful to understand that when a number has its square root taken with some degree n. The square root can be represented as just the value raised to the (1/n) power.

It's also helpful to understand that when you raise something to the power of another power, you can simply multiply the powers together. For instance (2^3)^5 = 2^15

Please help!!!! Anyone!!
Hoochie [10]

Answer:

  g(x) = |x -7|

Step-by-step explanation:

The form given for your answer has parameters 'a', 'h', and 'k'. The parameter 'a' is the vertical scale factor. Since g(x) is a translation only, that factor is 1. The parameters (h, k) identify the translation (right, up). The translation is 7 units right and 0 units up, so (h, k) = (7, 0).

Filling in these values of the parameters, your g(x) is ...

  g(x) = |x -7|
