C(h,k) radius(r)
C(2,-3) r=4
(x-h)^2 + (y-k)^2 = r^2
(x-2)^2 + (y--3)^2 = 4^2
(x-2)^2 + (y+3)^2 = 16
therefore, the answer is D
distance = speed x time
distance = 2.35 x time
distance = 2.35 x 5
distance = 11.75 feet in 5 minutes
Answer:
See below.
Step-by-step explanation:

because we combine like terms. You will essentially ignore the x and just do -2 + 1, which is -1. So, the answer would be -1x which is simply just -x.
To see why we can combine like terms, use the distributive property. So we have:

This is the same thing as saying:

Factor out the x:

Add:

And simplify:
