For a reflection over the x-axis, we have to change the sign of the y-value. In this case, from 13 to -13. So the reflection is (-6,-13).

Answer:
49/24
Explanation:
First, find the common denominator (24)
Secondly, multiply 2/3 by 8 since 8x3=24
Now you have 16/24 instead of 2/3
Thirdly, multiply 3/4 by 6 since 4x6=24
Now you have 18/24 instead of 3/4
Lastly, multiply 5/8 by 3 since 8x3=24
Now you have 15/24 instead of 5/8
Since you found the common denominator and changed all of the fractions you can add them all together.
16/24 + 18/24 + 15/24 = 49/24
Hope this helps!!!

Using these variables, we can set up equations.
3x + 5y = 42
9x + 7y = 72
We have here a system of equations, where we have two or more equations with two or more different variables. We use the elimination method to solve for the variables.
Multiply eq1 by 3. Keep eq2.
9x + 15y = 126 eq1
9x + 7y = 72 eq2
Subtract eq2 from eq1 to eliminate the x terms.
8y = 54
y = 6.75
