D is the answer when u solve the problem
Using the distance formula, when I plugged in the information, the answer I got was the square root of 85. (B)
Answer:
12.
-1.9 , -1.8, -1.7
13.
Points in Quadrant IV have a positive x, and a negative y.
14.
The point (2,9) is reflected over the y-axis, which means the number in x has it's sign flipped.
(-2 , 9) is your answer
15.
In between -7 & -4 is <em>-6, -5</em>
b. -6 is your answer.
16.
Remember that Quadrant II has a negative x, and a positive y. This means that b. (-2, 5) is your answer.
17.
You are reflecting over the y-axis, so you are changing the sign of the x value.
(-3, 5) reflected over the y-axis is a. (3 , 5)

Tan 18 = x/2
⇒ 0.3249 = x/2
⇒ x = 2 * 0.3249 =
⇒ x = 0.6498 ≈ 0.65
Hope it helps!
Answer:
True.
Step-by-step explanation:
Let a,b,c integers and a | (ab+c), that is to say that there exist a integer k such that ab+c = ka. Then:
ab+c = ka
c = ka-ab
c = a(k-b). So, c is a multiple of a, that is a | c.
