Step-by-step explanation:
10 cookies = 2 cups
20 cookies = 4 cups
30 cookies = 6 cups
We solve this by the definition of slope in analytical geometry. The definition of slope is the rise over run. In equation, that would be
m = Δy/Δx = (y₂-y₁)/(x₂-x₁)
The x-coordinates here are the t values, while the y-coordinates are the f(t) values. So, let's find the y values of the boundaries.
At t=2: f(t)= 0.25(2)²<span> − 0.5(2) + 3.5 = 3.5
Point 1 is (2, 3.5)
At t=6: </span>f(t)= 0.25(6)² − 0.5(6) + 3.5 = 9.5
Point 2 is (6, 9.5)
The slope would then be
m = (9.5-3.5)/(6-2)
m = 1.5
Hence, the slope is 1.5. Interpreting the data, the rate of change between t=2 and t=6 is 1.5 thousands per year.
First you should add +6 on both sides of the equation and then add -x so you will have:
2x - x = 4 +6 so x = 10 :)))

Answer:
1 because you can not buy 3/4 of a bag
Step-by-step explanation:
<span>d) y= -50t + 1000
You can re-arrange as
The amount of water left in the pool Y = 1000 gal at the beginning minus 50 gal x number of minutes passed. 1000 - 50t (or -50t+1000)
