(5,60)(10,40)
slope = (40 - 60) / (10 - 5) = - 20/5 = -4

y = mx + b
slope(m) = -4
(5,60)...x = 5 and y = 60
now we sub and find b, the y int
60 = -4(5) + b
60 = -20 + b
60 + 20 = b
80 = b

equation is : y = -4x + 80
function form : f(x) = -4x + 80...where x = number of weeks and f(x) = loads of waste removed

Find each unit rate <br> 1)78mi on 3gal<br> 2)$52.50 in 7 hours<br> 3)416 mi in 8 hours
Andreas93 [3]
1) Unit Rate = 26:1
We already know that for every 3 gallons, you can travel 78 miles. Divide 78 by 3 to get 26. The 26 stands for how many miles you can travel on one gallon.

2) Unit Rate = $7.50:1
Since we already know that for every 7 hours, you earn $52.50, divide 52.50 by 7 to get 7.50. The 7.50 represents how much money you earn in 1 hour.

3) Unit Rate = 52:1
Since you can travel 416 miles in 8 hours, divide 416 by 8 to get 52. The 52 represents how many mile you can travel in 1 hour alone.

Here's a little hint too: (If I remember correctly) For unit rates, it's always going to be *any number* to 1. So even if it's a decimal or a negative, the other side of the rate always has to be 1 :)

What is the common difference for this arithmetic sequence?
OleMash [197]

Answer:

Concept: Series

  1. Start by taking the first and second An and finding the difference
  2. You can then prove your result by taking any ordinary An and subtracting it by An-1
  3. Hence 45-39= 6
  4. To prove our result of 6; 39-33= 6
  5. Hence the common difference is
