Answer:
D
Step-by-step explanation:
Let's see if the lengths of these two segments are the same or not. We will use the distance formula, which says that for two points and , the distance between them is: .
For AB, is (-9, 12) and is (3, -6). So, the distance is:
For A'B', is (-3, 4) and is (1, -2). So, the distance is:
We can see that is 3 times of , which means that AB (the original) is 3 times the length of A'B' (the transformed).
Since the length has changed, we know that it must be some sort of dilation because that's the only kind of transformation that will change the length. We see that the segment has also shortened, which means that its scale factor must be less than 1.
The only answer that matches is D.
Hope this helps!
Answer:
well we don't don't know...because x is unknown
Answer: principal = $16.00
Step-by-step explanation:
P = A / (1 + rt)
P = 20 / (1+.05 x 5)
P = 20 / (1.25)
P = 16
Answer:
JL = 54
Step-by-step explanation:
JL = JK + KL
JK = KL
8x+11 =14x-1
12 = 6x
x = 2
substitute for x:
8(2)+11 + 14(2)-1 = JL
JL = 16+11+28-1
JL = 54
