Answer:
sugar| cookies
(cups) | (dozens)
1 | 2.5
2 | 5
3 | 7.5
4 | 10
Goes up by 2.5 each time
Not sure if this is what you want
Step-by-step explanation:
equation is y = 2.5x
1st piece = x
2nd piece = x+2
3rd piece = x+2+3 = x+5
37 = x +x+2 + x+5 =
37 = 3x+7
30=3x
x = 30/3 = 10
1st piece = 10 inches
2nd piece = 10+2 = 12 inches
3rd piece = 10+5 = 15 inches
Three equivalent ratios of 48:36 are 12:9 ,24:18 ,16:12.
Slope is 2
Y intercept is 4
Answer:
Average rate of change = $11250 per year.
Step-by-step explanation:
Let's take two points from given information (2006, 90000) and (2010, 135000).
Now, use slope formula to find slope.
Slope =![\frac{y2-y1}{x2-x1}](https://tex.z-dn.net/?f=%5Cfrac%7By2-y1%7D%7Bx2-x1%7D)
Use the two points to find average rate of change (slope)
Average rate of change =![\frac{135000-90000}{2010-2006}](https://tex.z-dn.net/?f=%5Cfrac%7B135000-90000%7D%7B2010-2006%7D)
=![\frac{45000}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B45000%7D%7B4%7D)
=11250
Average rate of change = $11250 per year.
