Answer:
y=3 x=-20
Step-by-step explanation:
2(3y-5)+12y=-4
6y-10+12y
18y-10=-4
18y=6
y=3
2x+12(3)=-4
2x+36=-4
2x=-40
x=-20
69
B. The typical value is greater in set A. The spread is greater in set B.
Slope is m= -1
Use the slope formula to find the slope m .

Maria: 2x
Ana: 3x
2x + 3x = 20000
5x = 20000
x = 20000/5
x = 400
2× 400
8000
Anna: 3x
3 × 400
12000
