Answer:
a reflection over the x-axis and then a 90 degree clockwise rotation about the origin
Step-by-step explanation:
Lets suppose triangle JKL has the vertices on the points as follows:
J: (-1,0)
K: (0,0)
L: (0,1)
This gives us a triangle in the second quadrant with the 90 degrees corner on the origin. It says that this is then transformed by performing a 90 degree clockwise rotation about the origin and then a reflection over the y-axis. If we rotate it 90 degrees clockwise we end up with:
J: (0,1) , K: (0,0), L: (1,0)
Then we reflect it across the y-axis and get:
J: (0,1), K:(0,0), L: (-1,0)
Now we go through each answer and look for the one that ends up in the second quadrant;
If we do a reflection over the y-axis and then a 90 degree clockwise rotation about the origin we end up in the fourth quadrant.
If we do a reflection over the x-axis and then a 90 degree counterclockwise rotation about the origin we also end up in the fourth quadrant.
If we do a reflection over the x-axis and then a reflection over the y-axis we also end up in the fourth quadrant.
The third answer is the only one that yields a transformation which leads back to the original position.
Answer:
<h3> D){?}
x = 7</h3>
Step-by-step explanation:
x + 3•(+1) = 2•x + 4•(-1)
x + 3 = 2x - 4
-3 -3
x = 2x - 7
-2x -2x
- x = -7
÷(-1) ÷(-1)
x = 7

Step-by-step explanation:
This sentence does not give us enough information or the needed information to know how many of each kind of fruit are put into the bag, but it does give the needed information to know how many ounces each piece of fruit weighed which was 4.75 oz per piece of fruit.
