Question

PLZ HELP I've been working on this for half the day, and I can't stand it. Solve and show your work.

Answer 1

• (5, 50)

Explanation:

Equation for weight of toy cars:

• y = 9x + 5

Equation for weight of toy trucks:

• y = 6x + 20

Solving the system by substituting y:

• 9x + 5 = 6x + 20
• 9x - 6x = 20 - 5
• 3x = 15
• x = 15/3
• x = 5
• y = 9*5+5 = 50

Intersection point is (5, 50)
