A group of friends wants to go to the amusement park. They have $134.75 to spend on parking and admission. Parking is $12.25, and tickets cost $24.50 per person,
including tax. Write and solve an equation which can be used to determine x, the
number of people who can go to the amusement park.

Which is the graph of the piecewise function f(x)? f(x)=[tex]f(x) = \left \{ {{-x+1, x\leq 0 } \atop {x+1, x\ \textgreater \ 0}} \right.[/tex]

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
