A) 3x + 4 = 5x - 10. It's easy to identify the lines' equations by their y-intercept and slope.
Make an equation:
L = 4S - 3
Where 'L' is the amount of DVD's Leah has and 'S' is the aount of DVD's Sonia has.
Plug in 37 for 'L' and solve for 'S':
37 = 4S - 3
Add 3 to both sides:
40 = 4S
Divide 4 to both sides:
S = 10
So Sonia has 10 DVD's.
2(4)2 - 10 / 2 = 8(2) - 10 / 2 = 16 - 5 = 11 (FINAL ANSWER)
