Step-by-step explanation:

$\frac{1}{100} = \frac{1}{ {10}^{2} } = {10}^{ - 2} \\ \\ reason \\ \: \because \: \frac{1}{ {a}^{2} } = {a}^{ - 2} \\ \\ \implies \: \frac{1}{ {10}^{2} } = {10}^{ - 2}$

Can someone help me?

Answer:

y = 2.1x +5, 21 miles

Step-by-step explanation:

We will denote miles as "x"

Since she tipped the driver $5, that is a flat rate and that will be our y-intercept. Since it costs $2.10 per mile, we need to multiply that number by the number of miles

So our equation will be y = 2.1x +5

In order to figure out how many miles Ann lives from the airport, we need to substitute y for her grand total that she was charged

This gives us 49.10 = 2.10x + 5

First we need to subtract 5 from each side to get 44.10 = 2.10x

We then need to divide both sides by 2.10 to get 21 = x

Ann drove 21 miles
