plz help no one is .. question below
A school system is reducing the amount of dumpster loads of trash removed each week. In week 5, there were 60 dumpster loads of waste removed. In week 10, there were 40 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. f(x) = - 4x + 60 f(x) = 4x + 60 f(x) = - 4x + 80 f(x) = 4x + 80
@mathstudent55 plz help
@sleepyjess help :(
Just substitute in the numbers and see which one works out. x = 5, y = 60 x = 10 y = 40
i still don't get it
i got choice a the first time i did it
Substitute in 5 for x in the first equation. y = -4(5) + 60 y = -20 + 60 y = 40 Welp, week 5 is supposed to be 60, so the first option isn't right.
oh i see give me a sec
so it's C?
Yep, that works with both values of x y = -4x + 80 y = -4(5) + 80 y = -20 + 80 y = 60 That works y = -4x + 80 y = -4(10) + 80 y = -40 + 80 y = 40 That works too
OK thnz
