Answer:
Arnez is 4. Andell is 13. Marianne is 7.
Step-by-step explanation:
Let x represent Arnez's age. If we write out an equation, we end up with this:
24 = (9 + x) + (x + 3) + x
24 = 9 + x + x + 3 + x
24 = (x + x + x) + (9 + 3)
24 = 3x + 12
24 - 12 = 3x + 12 - 12
12 / 3 = 3x / 3
4 = x
y= mx+b
(16, -7) = (x,y)
2(16) - 3y = 12
32 - 3y = 12
32 - 12 = 3y
20/3 = y
6.6 = y
2x-3(-7) = 12
2x+21 = 12
2x = 12 - 21
x = -9/2
Insert the values into y = mx + b
solve for m and then solve for b
