A reflection is a transformation across a line called the line of reflection, so that the line of reflection is the perpendicular bisector of each segment joining each point and its image. ... A translation is an isometry , so the image of a translated figure is congruent to the preimage.
Answer:
6
Step-by-step explanation:
So to find how much sheep there were on each acre, you divide.
250/40
You do this because you are splitting the 250 sheep into 40 acres.
250/40 = 6.25
There cannot be .25 of a sheep, and since it says on average the answer does not need to be exact. So you would round it off to 6 as your answer.
Answer:
second picture
Step-by-step explanation:
The rule to rotate a point counterclockwise about the origin is:
Or in words, we switch the coordinates of the point and change the sign of the y-coordinate.
We know from the first picture that the coordinates of our quadrilateral ABCD are A = (-1, 0), B = (0, -1), C = (-2, -3), and D = (-3 , -2), so let's apply the rotation rule to each one of those points:
Now we know that the coordinates of the quadrilateral after a rotation of 90° are A' = (0, 1), B' = (1, 0), C' = (3, -2), and D' = (2, -3), which corresponds to the second picture
Answer:
x=11, y=10
Step-by-step explanation:
x= 6+ (1/2)y
x+y=21
substitute the first equation into the second equation:
(6+ (1/2y)) + y =21
to get:
y=10
then to find x:
x+ 10 = 21
x=11
