Ahistoric museum charges a rental fee plus $2 per hour for an audio tour guide. the total cost for 4 hours is $12. find and interpret the rate of change and initial value.

We can represent this problem with the following linear equation
 y = 2x + 4
 where
 y: total cost
 x: number of hours
 the slope of the line is
 m = 2
 Which means that for every hour of audio tour guide they charge $ 2.
 For "zero" hours (x = 0) a rental fee of $ 4 must be paid.

Four Common Tangents, (n = 4)

Step-by-step explanation:

The next to last case is where the centers of the circles are far enough apart that the circles are completely separated. This is probably the most common case, and is defined by the relationship: d > a + b. There are 2 internal common tangents and two external common tangents.

not sure it's help!

sorry
