Arental car company charges $0.50 per mile and a flat rate of $30.00 for any type of sedan. if m represents the number of miles driven and c(m) represents the total cost for renting a sedan, what is the linear equation that represents a cost of $130? 30 = 0.50m + 130 30 = 130m + 0.50 130 = 0.50m + 30 130 = 30m + 0.50

Consider the function f left parenthesis x right parenthesis equals 4 x squared minus 3 x minus 1f(x)=4x2−3x−1 and complete parts (a) through (c). (a) find f left parenthesis a plus h right parenthesis f(a+h); (b) find startfraction f left parenthesis a plus h right parenthesis minus f left parenthesis a right parenthesis over h endfraction f(a+h)−f(a) h; (c) find the instantaneous rate of change of f when aequals=77.
