1.Given the linear inequality x+2y≤12, what error was made when graphed? 2.The point (5, 4) is not a solution to the inequality. Why? Explain your reasoning using the graph and using algebra.

Explain how you do each step what term makes it inconsistent y=2x - 4 ?

The u-drive rent-a-truck company plans to spend $13 million on 320 new vehicles. each commercial van will cost $25 comma 000, each small truck $50 comma 000, and each large truck  $80 comma 000. past experience shows that they need twice as many vans as small trucks. how many of each type of vehicle can they buy?

What are the solutions of the system? solve by graphing. y = x^2 + 3x + 2 y = 2x + 2
