The formula is (x-h)^2+(y-k)^2=r^2
so, using this, and knowing that h is -3 and k is -5 and r is 4, we get
(x--3)^2+(y--5)^2=(4)^2, which equals
(X+3)^2+(y+5)^2=16

Answer:
no solution
Step-by-step explanation:
given the 2 equations
- 2x + 3y = 18 → (1)
3y = 2x + 5 → (2)
we can substitute 3y = 2x + 5 into equation (1)
- 2x + 2x + 5 = 18 ( collecting like terms gives )
5 = 18 ← not possible
Hence the system of equations has no solution
Dependent variable is dependent on the independent variable
independent variable influences the dependentvariable
number of months influences the hcost
independent=number of months
dependent=cost
for the cost for 4 or 2 months, just start at months=2 or 4 and go up till you hit the line
equation=y=mx+b
m=slope
b=yintercept or starting point
solid line
initial fee=20
see attachment, black lines are what they are
2 months=$80
4months=140
rate is $30 per month
equation is c=30m+20
dashed line
intial fee=50
attachment, blue is dashed points
2months=$70
4months=$90
rate is $10 per month
equation is y=10x+50
So this is what you can do count to four four time
