Answer:
Right
Step-by-step explanation:
A right triangle has acute angles and is an equilateral triangle.
Answer:
the origin, (0, 0)
Step-by-step explanation:
The coordinates of A' are 1/2 those of A, meaning each has been multiplied by the scale factor 1/2. When the dilated points are all the original points multiplied by the scale factor, the center of dilation is the origin.
_____
For center of dilation Q, the image of a point A after dilation by a factor of k is ...
A' = kA + (k-1)Q
Then for points A, A', and dilation factor k, the center of dilation can be found to be ...
(A' -kA)/(k-1) = Q
Here, that is ...
Q = ((-2, -2) -(1/2)(-4, -4))/(1/2 -1) = (0, 0)/(-1/2)
Q = (0, 0)
You know the first terms of the factors must be 7 & 1, since those are the only factors of 7.
So you write:
Both the second and third term are positive, so x & y are both positive.
From there, all you can really do is plug in all factors of 36 as x or y until you find that the second term adds up to 67.
And you find the only one that works is:
Answer:
Answer is $3
Step-by-step explanation:
$3 x 0.75 (75%) = $2.25
$3 - $2.25 = $0.75
