Question

A school system is reducing the amount of dumpster loads of trash removed each week. In week 5, there were 40 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.

f(x) = - 2x + 40

f(x) = 2x + 40

f(x) = - 2x + 50

f(x) = 2x + 50

Answer 1

I think it's C, but I assumed that with logic

Answer 2

im trying to understand the question still

Answer 3

lets plot the two points

Answer 4

f(x)=-2x+50

f(5)=-10+50
f(5)=40

f(10)=-20+50
f(10)=30

Answer 5

Okay

Answer 6

(5, 40)

(10. 30)

Answer 7

wow ! you're brilliant

Answer 8

that works when u have options !

Answer 9

y2-y1/x2-x1
30-40/10-5
-10/5
-2

y=-2x+b

30=-2*10+b
30=-20+b
50=b

y=-2x+50

Answer 10

That's if I do it your way haha :)

Answer 11

no, i liked ur logic it was quick

Answer 12

good job :)
