It is given that
Solving for
we get

♥It says that he adds 12$ each week, and by the end of 3 weeks he had 60. Well if you do 12*3
And that =36.
But as you can see its not 60 so we have to find out how much money he had in there before.
He had 24$ in there before he started doing this.
You can find this by doing 36+x=60 and 36+24=60.
Now if you do 12*15
You get 180.
Now add the 24 dollars he already had in there.
180+24=204
He had 204$ at the end of wk.15

Answer:
y = 2x
Step-by-step explanation:
General Form is the most basic form of an equation and is used as a template to form equations designed to solve a specific problem.
The equation given is "<span>(x- -1)^2 +(y-1)^2 =225.0".
The general form of this Equation would be presented as
</span>·X (+/-) Y = Z
·X^2 (+/-) Y^2 = R1
