Answer:
B. (x-5)²+(y+1)² = 49
Step-by-step explanation:
An equation of a circle with center (h, k) and radius r is

We have all given information we need. Our h is 5 - Our k is -1 and our radius is 7
Substitute these values in

So the answer is B choice.
Answer:
3/12 = 1/4
Step-by-step explanation:
There are 12 marbles in the bag. If the marble drawn at random is red, it is one of the 3 red marbles.
The probability is "3 out of 12" = 3/12 which simplifies to 1/4.
Answer:
actual length = 171.67 ft.
Step-by-step explanation:
scale of school bus drawing is 12 in. to 5 ft.
if the length of a school bus drawing is 412 in.
5 ft
the actual length is = 412 in x --------
12 in
actual length = 171.67 ft.
The answer would be
y = 4x -14
y +2 = 4(x-3)
y+2 = 4x -12
y = 4x -12 -2
y = 4x -14 (slope intercept form)
D = (5-1)/(13-(-3)) = 0.25
f(13) = 13d + x = 13 * 0.25 + a = 3.25 + a = 5
a = 1.75
f(x) = 1.75 + 0.25x
