Answer:
-2,4
Step-by-step explanation:
i just did it
A’=(1,.5) you just multiply the points by whatever the dilation is, so by .5
Answer:
No, they are not congruent
Step-by-step explanation:
By CD and EF being congruent, we want to know if they are equal.
What we can simply do here is to find the distance between the points present.
That is, the distance between C and D, the distance between E and F
To get the distances between two points , we use the following equation
D = √(x2-x1)^2 + (y2-y1)^2
For CD, we have
D = √(6 -(-1)^2 + (-7 + 7)^2
D = √(7)^2 = 7 units
For EF, we have
D = √(5-5)^2 + (-5-3)^2
D = √(-8)^2
D = √(64) = 8 units
This clearly shows that they are both not congruent
Answer:
x = -2
Step-by-step explanation:
x+8 = 2x +10
-2x + x = 10-8
-x = 2
divide both side by -1
answer -- x = -2
