First, coordinate Q is (-5,2) and Q' is (6,2). First, we know that this is a horizontal reflection becuase only the x-values change. This means that the line of reflection will be x=some value. I think the best way to go about this is to find the midpoint of Q and Q' using the formula: M=(x1+x2/2,y1+y2/2)
Q is the first point and Q' is the second point
M=(-5+6/2,2+2/2)
M=(1/2,4/2)
M=(1/2,2)
Since we know the y-values of Q, Q', and the midpoints are all 2, then the line of reflection would be x=1/2
Hope this helps
Answer:
A is 6
B is 9.4
Step-by-step explanation:
First you put the numbers in order. then you take the middle number of the data set. This is how you find the median. For the mean you add all of the number in the data set then divide by how many numbers are there

Answer:
x=3y
Step-by-step explanation:
Step 1: flip the equation.
2x−5y=y
Step 2: Add 5y to both sides.
2x−5y+5y=y+5y
2x=6y
Step 3: Divide both sides by 2.
2x
2
=
6y
2
x=3y
-16 = m + 71
Move +71 to the other side. Sign changes from +71 to -71. To get m by itself.
-16-71=m+71-71
-16-71=m
-87=m or m=-87
Answer: -87=m or m=-87
