Answer:
J'(7,-4), K'(-7,-1), L'(-2,2)
Step-by-step explanation:
reflection over x-axis: (x,y) --> (x,-y)
reflection over y-axis: (x,y) --> (-x,-y)
Because the triangle is reflected x-axis and then y-axis,
all points would be (x,y) --> (-x,-y)
Answer: Depends....could be anything...one example is 8/14
0-9 = 4
10-19 = 3
20-29 = 9
30-39 = 5
5
Total goals /total no. of matches = 4
5+7+4+2+4+0+5+5+3+x / 10 = 4
35 + x = 4 × 10
x = 40 - 35
x = 5
So, the team must score 5 inorder to get the average of 4 goals per match.
42
f(-5) = -9 × (-5) - 3 = 45 - 3 = 42
