Answer:
the correct answer should be A
Answer:
income=2*expenses-100
Step-by-step explanation:
income=a*expenses+b
a:slope
a=(income of 1 - income of 0)/(expenses of 1 - expenses of 0)
=(10-0)/(55-50)=10/5=2
income=2*expenses+b
for product 0
income=0
expenses=50
》0=2*(50)+b
b=-100
income=2*expenses-100
The center would be (5, 7), and the radius would be √(12-7)²+(10-5)² = 5√2.
Standard form is (x-h)²+(y-k)²=r², where (h, k) are the coordinates for the center of the circle, and r is the radius.
So we get (x-5)²+(y-7)²=50.

Hope this helps!
Probably infinite depending on if u mean how many factors it has
