Answer:

Step-by-step explanation:

Circle with centre (0,2) will have the equation

(x)²+(y-2)² = r²

Finding r² by distance formula using P(-7,2)

r² = (-7-0)²+(2-2)²

r² = (-7)²

r² = 49

So substituting in the equation

x²+(y-2)² = 49

Three brothers, Justin, Jared, and Jonathan decided to buy a present for their mom's birthday. Justin gave decided to spend 1/4
iVinArrow [24]
I believe that, if there are three brothers and each invested the same exact money to make a total of $33.00, each brother would have invested $11.

Jonathan's was different, as he invested 2/5. 11 divided by 2 is 5.5, in which 5.5*11 would equal 27.50.
The rest was simply their denominator times $11.
Jared had $33 dollars before the investment, and Justin has $44.

Cross multiply!!

Divide 7 on both sides.
