Answer:
x = 2 and y = 1
Step-by-step explanation:
4x = 5+3
4x = 8
x = 8/4
x= 2
so substitute the value of x in the second problem
-8(2) + 6y = -10
-16 + 6y = -10
6y= -10 + 16
6y= 6
y= 6/6
y = 1

Answer:
The reflection of point S across the y-axis is point <u> V </u>. The reflection of point Q across the x-axis and the y-axis is point <u> V </u>, whose coordinates are ( <u> -5 </u> , <u> -5.5 </u>).
===============================================
Explanation:
Point S is exactly 5 units away from the vertical y axis. Move from point S(5,-5.5) to the location (0,-5.5); ie move 5 units to the left. Then move another 5 units to the left to land on point V(5, -5.5)
Points V and S are the same distance away from the mirror line.
-----------------------
Reflecting point Q over the x axis lands us on point S. This time we move down 5.5 units to get to the x axis. Then move another 5.5 units to arrive at point S. As discussed above, point S then will reflect over the y axis to get to point V.
Side note: Combining two reflections produces a rotation. So effectively, going from Q to V is a rotation of 180 degrees.
