Answer:
d. (2, -4)
Step-by-step explanation:
The equation describes a circle centered at (2, -3) with a radius of 2.
Any points with an x-coordinate of 2 must have a y-coordinate in the interval -3±2 = (-1, -5) to be inside the circle. One such point is ...
(2, -4) . . . . choice D
__
The attached graph shows the locations of the answer choices.
C, because if it was D, they would be the same, which is A written in another format. Then process of elimination
The gcf of 64 and 16 is16
Answer:
Step-by-step explanation:
Let C(x) be the cost to produce x batches of widgets, and let R(x) be the revenue in thousands of dollars.

Profit function = Revenue - cost
So we get profit function by subtracting C(x) from R(x) using algebraic method of subtraction.
Profit function of x
= 
Answer: 1. 75582 2. 3047466240
Step-by-step explanation: 1. If order does not matter, this is a combination problem. You are choosing 8 sticks from a set of 19. (Octagons have 8 sides.) The formula for combinations of n things chosen r at a time "n choose r" is
2. If order matters, there are more possibilities. This is a permutation problem. The number of permutations of 19 things taken 8 at a time, "19 permute 8" is Y
