If a medium pizza costs $5 and a large pizza is $8, write an equation in standard form that models the possible combinations of you have $40. (let m=medium and l=large.)

The graph of f(x) is obtained by reflecting the graph of f(x)=-3|x| over the x-axis. which equation describes f(x)? a) f(x)=3|x| b) f(x)=|x+3| c) f(x)=-3|x| d) f(x) = - |x+3|
