miss Akunina [59]3 years ago
3 0

Answer:

1. 2³ × 2² = (2 × 2 × 2) × (2 × 2) = 23+2 = 2⁵

2. 3⁴ × 3² = (3 × 3 × 3 × 3) × (3 × 3) = 34+2 = 3⁶

3. (-3)³ × (-3)⁴ = [(-3) × (-3) × (-3)] × [(-3) × (-3) × (-3) × (-3)]

= (-3)3+4

= (-3)⁷

4. m⁵ × m³ = (m × m × m × m × m) × (m × m × m)

= m5+3

= m⁸

The graph shows the average price of homes in the United States from 2009 to 2014.
Leya [2.2K]

Answer:

Rising home prices in recent years means that more people will need to take out mortgages.

Explanation:

We can see in the graph that there is an upward trend; that is, the average price of homes in the US is rising.  While there was a slight decrease from 2010 to 2012, overall the average is still increasing.

Since the prices are increasing, more people will need to take out mortgages, as it will e harder to have the cash saved up to purchase the home.

The following linear equation represents the line of best fit for the following scatter plot
Burka [1]

Answer:

C) 28.5 home runs

General Formulas and Concepts:

<u>Pre-Algebra </u>

Order of Operations: BPEMDAS

  1. Brackets
  2. Parenthesis
  3. Exponents
  4. Multiplication
  5. Division
  6. Addition
  7. Subtraction
  • Left to Right

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>

y = home runs

x = hits

[Best Line of Fit] y = 0.15x - 1.5

<em>We can use this to predict the average of the scatter plot. </em>

hits = x = 200 times

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

  1. Substitute [BLF]:                     y = 0.15(200) - 1.5
  2. Multiply:                                  y = 30 - 1.5
  3. Subtract:                                 y = 28.5

Remember that this is only a <em>prediction.</em> Actual data can vary. The best line of fit tells us that if a player hits 200 times, we would get approximately 28.5 home runs.
