MatroZZZ [7]

Answer:

B.

General Formulas and Concepts:

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

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

f(x) = 8x + 4

<u>Step 2: Prep</u>

  1. Rewrite:                         y = 8x + 4
  2. Swap <em>x</em> and <em>y</em>:               x = 8y + 4

<u>Step 3: Find Inverse (Solve for </u><em><u>y</u></em><u>)</u>

  1. Subtract 4 on both sides:                    x - 4 = 8y
  2. Divide both sides by 8:                       (x - 4)/8 = y
  3. Rewrite:                                                 y = (x - 4)/8
  4. Rewrite:                                                f⁻¹(x) = (x - 4)/8

The distance between the baseball stadium and the airport is 1.6×10^6 centimeters.Which unit of measurement is most appropriate
Ad libitum [116K]

Answer:

<em>'Kilometers' is the most appropriate unit to measure this distance. </em>

Step-by-step explanation:

The distance between the baseball stadium and the airport is  1.6\times 10^6 centimeters.

(1.6\times 10^6)cm = (16\times 10^5)cm

Now,  <u>10⁵ centimeters is equal to 1 kilometer</u>.

That means,  (16\times 10^5)cm = (16\times 1)km= 16 km

So, 'Kilometers' is the most appropriate unit to measure this distance.
