Erin buys gas at a self service station for $2.75 a gallon. the gas station has a promotion going on that anyone who buys more than 10 gallons of gas, only has to pay $2.50 per gallon. erin's tank will hold 12 gallons of gas.
a) write a rule for the total cost, c(g), as a function of g gallons of gas.
b)graph the piecewise function
c)what is the domain and range of the function in part a

Which one is true about the hexagons ?

Which graph represents the equation y =4x

Triangle xyz, with vertices x(-2, 0), y(-2, -1), and z(-5, -2), undergoes a transformation to form triangle x? y? z? , with vertices x? (4, -2), y? (4, -3), and z? (1, -4). the type of transformation that triangle xyz undergoes is a . triangle x? y? z? then undergoes a transformation to form triangle x? y? z? , with vertices x? (4, 2), y? (4, 3), and z? (1, 4). the type of transformation that triangle x? y? z? undergoes is a .
