Reflecting a function across the x-axis means to change the sign of the function itself: you're mapping
So, if you have a x/y values table, you simply have to change sign to all the values in the y column.
The six scores have to average out to the mean, so their sum has to be six times the mean. Since the sum of the first five is 5 more than 5 times the mean, the remaining score must be 5 less than the mean.
Answer: 5 points below the mean
Answer:
RS is about 18.615
Step-by-step explanation:
since XY is the midsegment, it is parallel to the other 2 lines. That also makes the lines proportional
cross multiple
484=26x
x= 18.615
Answer:
the answer is 469
Step-by-step explanation:
Answer:
(-9,3)
Step-by-step explanation:
6x and -6x cancel, leaving us 12y=36 which means y=3. Then we can plug it back into our equations leaving us with x=-9.
