Answer:
Five students wear glasses.
Step-by-step explanation:
20 percent of 25 is 5
P(-3,-8) Q(-6,4) R(1,-1). Because it reflects over the x-axis the x values stay the same and the y values change signs.
1: (-1,-1) is (x, y) to see if it is a solution, you would just plug in x and y and see if the equation is true.
-4 (-1) + 2(-1) = 2
4 + -2 = 2
2 = 2 CORRECT
So... plug in x and y in the second equation to Make sure it works for that one too.
-1 + -1 = -2
-2 = -2 CORRECT
So, yes. (-1,-1) is a solution to both equations.
