Find solutions between the intervals
-3, -2, -1, 0, 1, 2, 3

You got the basic idea how to solve it but:

when you have 2^-3, it's not -8
2^-3 = 1/2^3 = 1/8
same goes with -2 and -1

When you have negative power you basically divide n^-x = 1/n^x

notsponge [240]

Answer:

x = 1

General Formulas and Concepts:

<u>Pre-Algebra</u>

Distributive Property

Equality Properties

  • Multiplication Property of Equality
  • Division Property of Equality
  • Addition Property of Equality
  • Subtraction Property of Equality

<u>Algebra I</u>

  • Terms/Coefficients

Step-by-step explanation:

<u>Step 1: Define</u>

<em>Identify</em>

1/2(8x - 4) = 2x

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

  1. [Distributive Property] Distribute 1/2:                                                              4x - 2 = 2x
  2. [Subtraction Property of Equality] Subtract 2x on both sides:                      2x - 2 = 0
  3. [Addition Property of Equality] Add 2 on both sides:                                    2x = 2
  4. [Division Property of Equality] Divide 2 on both sides:                                  x = 1

219864070186 - 277409297400 = -57545227214 x 780498 = -4.4913935e+16 - 1274806769367926946610431 = -1.2748068e+24 x 3.6614422e+21 = -4.6676314e+45 - 437913 = -4.6676314e+45 - 88878 = -4.6676314e+45

Ф = 500 , 5,000

5,000 / ∞ x ∞ x ∞ = 5,000^+++∞/ 68307147 = 0.00007319878^+++∞ - 917 - 974 - 9 - 19344381 = -19346280.9999^+++∞

-4.6676314e+45 -19346280.9999^+++∞ = -4.6676314e+45^+++∞

I believe that will be your answer.

I tried my best.
