tamaranim1 [39]

Answer:

<u>The average speed or proportionality constant (y to x) of Jean biking from Pine Buff to Newberry to go to the charity event was 15 miles per hour</u>

Step-by-step explanation:

1. Let's review the information provided to us to answer the question correctly:

Distance from Pine Bluff to Newberry (y axis) = 75 miles

Time it took Jean to rode her bicycle (x axis) = 5 hours

2. The proportionality constant (y to x) is?

We can calculate the answer this way:

Proportionality constant (y to x) = Distance from Pine Bluff to Newberry (y axis)/Time it took Jean to rode her bicycle (x axis)

Substituting with the real values, we have:

Proportionality constant (y to x) = 75/5

Proportionality constant (y to x) = 15 miles per hour

<u>The average speed or proportionality constant (y to x) of Jean biking from Pine Buff to Newberry to go to the charity event was 15 miles per hour</u>

I need a little help -
OverLord2011 [107]

Answer:

(6x6x6x6) x (6x6x6)

Step-by-step explanation:

6 to the power of four is just 6 multiplied to itself 4 times.

6 to the power of three is just 6 multiplied to itself 3 times.

So, you would be multiplying 6, 7 times.

You could check it with a calculator. - 6^4 x 6^3 = 279936.

6^7 = 279936.
