S=-4r-2 tell me if I'm wrong cuz I'm not very great a math but I want to try the question out
Well it sounds like you mean smaller, not greater. 3/300 = 1/100 while 3/30 = 1/10. So 3 out of 300 is 10 times SMALLER than 3 out of 30.
Since the example circle is not shown, I can not answer thoroughly, but I will try my best.
The equation of a circle: (x - h)² + (y - k)² = r², where (h,k) is the center and r is the radius of the circle.
This means that for the radius to be two units, the right side of the equation is 2² = 4. So either B or d can be right.
Depending on the center of the given circle, we could narrow down to our final answer. If the center is (4,5), B is right, and if (5,4) is the center, D is right.
A. 2n should be Bill's age
B. 2n + 5 should be Sam's age

Her score was B: -3
This is because: -4-3+5-3+2=-3
Hope it is helpful :)
