Answer:
Step-by-step explanation:
radius =( (8+7)^2 + (7+1)^2 )^1/2 = 17 unit
Equation of the circle = (x + 7)^2 + (y+1)^2 = 17^2
= (-15+7)^2 + (y+1)^2 = 17^2
=14
(-15, 14) lies on this circle
Well, from those 560, 200 are from her salary, and the rest is commissions from sales, so.... 360 is the 5.5% she's got, now, if we take "x" to be the 100% for the sales, then

solve for "x".
Translating this verebal statement into a symbolic statement:
8 - 15/y = 13y.
Note: your statement would sound better if written as "8 minus the quotient of 15 and y equals the product of y and 13."
Answer:( -3,1)
X=-3 y=1
