Hello peepers! i need asap .
a school system is reducing the amount of dumpster loads of trash removed each week. in week 5, there were 45 dumpster loads of waste removed. in week 10, there were 30 dumpster loads removed. assume that the reduction in the amount of waste each week is linear. write an equation in function form to show the amount of trash removed each week.
a. f(x) = −3x + 45
b. f(x) = 3x + 45
c. f(x) = −3x + 60
d. f(x) = 3x + 60

The answer would be C because you are subtracting 3 by a number(x) because you are REMOVING garbage. And if you remove the x from 3x and replace it with the number of weeks, you'll get the number of loads dumped. For example -3(5)+60. Follow your order of operations. Multiply first to get -15. Then add that to 60. You will get 45, which is the correct answer because in the problem, the number of loads are 45. Or how about this, -3(10)+60. Multiply first to get -30, then add positive 60 to get 30 overall. Since 30 is the number of loads removed in the problem, your answer is correct, thus, making the correct equation C.
