The equation of a line that passes thruogh the point (x1,y1) and has a slope of m is
y-y1=m(x-x1)
so
passing through (a,b) and having slope of b is
y-b=b(x-a)
Claim: The measures of
and
are equal
Answer: True
Explanation: Dilations preserve the shape of an image, so this means the angles are kept the same whether you shrink or enlarge the preimage.

Claim: The coordinates of A and A' are the same
Answer: True
Explanation: The phrasing "dilating about point A" means that point A is the center of the universe, so to speak, in terms of this dilation operation. Point A is the fixed point that does not move while every other point does move. Because the scale factor is 2/3, which is less than 1, this means every other point comes closer to point A. So something like segment AB will get shorter.
X / 6/7 is 3 2/5. First, concert the numbers to decimals for simplicity sake, and you get x/.857 = 3.4. Multiply both sides by .857 to get x alone and you get x ≈ 2.9143
Answer:
<h2>8 or -8</h2>
Step-by-step explanation:
The absolute value of number a:
|a| = a for a ≥ 0
|a| = -a for a < 0
|a| = 8 ⇔ a = 8 or a = -8
The answer would be A. I hope this helps you
