question
graph this system of equations.
1.15x + 0.65y = 8.90
x - 3y = -15

Explanation:

Answer:

For \(1.15x + 0.65y = 8.90\), find two points: when \(x = 0\), \(y=\frac{8.90}{0.65}\approx13.69\); when \(y = 0\), \(x=\frac{8.90}{1.15}\approx7.74\). For \(x - 3y=-15\), rewrite as \(y=\frac{1}{3}x + 5\). When \(x = 0\), \(y = 5\); when \(y = 0\), \(x=-15\). Plot these lines.
