At jason's car rental shop it costs a flat rate of $100 to rent a car, which covers the cost of driving up to 75 miles. for every mile over 75 it costs an additional $0.10. write a piecewise function modeling this situation, where x represents the miles driven and y represents the total cost.

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.

step-by-step explanation:

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180
