A rigid transformation is
defined to be one in which the pre-image of the object and its new image after
the transformation both have the exact same size and shape. So the answer
in this question is:
<span>D. a circle's shape is preserved regardless of any rigid
transformation</span>
Answer:
a) the number of miles in 1 kilometer
Step-by-step explanation:
The car converts from miles/hour to kilometers/hour, if we see the time measurement (hours) it stays the same in both units.
So to make the conversion<u> it is enough to know how many miles are in one kilometer.</u>
For example, lets convert 10miles/hour to kilometers/hour.
there are 0.621371 miles in 1 kilometer, so if we divide 10miles/hour by 0.621371 we get kilometers/hour units:

Thus to make the conversion between the two units is needed the number of miles in 1 kilometer.
For question 1 the answer is B.
for question 2 the answer is C.
X-y=-10
x=-10-y
7x+7y=-14
7(-10-y)+7y=-14
-70-7y+7y=-14
0y=56
y=0
x=-10-y
x=-10-0
x=-10
I’m not 100% sure if this is right, so I hope someone checks this over :)
In order to solve for r you have to place all the number in one side. then isolate r ...... r=1
