Answer:

<em>( x + 5 )² + ( y + 4 )² = 29 </em>

Step-by-step explanation:

Equation of the circle is

( x - h )² + ( y - k )² = r²

( h, k ) are coordinates of the center

~~~~~~~~~~~~~~~~~~~~~

Coordinates of the center of the circle are

( \frac{-3-7}{2} , \frac{-9+1}{2} ) = ( - 5 , - 4 )

d = 2√29 ⇒ r = √29

<em>( x + 5 )² + ( y + 4 )² = 29</em>

Alinara [238K]

The monthly rate is $45 for this cellphone plan.

Step-by-step explanation:

Given,

Amount charged for cell phone = $60

Amount paid by Regina for 24 month plan = $1140

Number of months = 24

Let,

m be the monthly rate for cellphone plan

Number of months * Monthly rate + cellphone charges = Amount paid

24m+60=1140\\24m=1140-60\\24m=1080

Dividing both sides by 24

\frac{24m}{24}=\frac{1080}{24}\\m=45

The monthly rate is $45 for this cellphone plan.
