A cookie recipe that yields 48 cookies calls for 2 cups of flour. a different cookie recipe that yields sixty cookies calls for
3 cups of flour. are these rates proportional
1 answer:
48 cookies from 2 cups of flour, rate = 48 cookies / 2 cups = 24 cookies / cup
60 cookies from 3 cups of flour, rate = 60 cookies / 3 cups = 20 cookies / cup
If the rates were proportional, the rates would have the same answers.
Therefore the rates are not proportional.

Answer:
the answer is 3.37723077E13
Step-by-step explanation:
The slope would be 1/17 and then you would use that slope and plug it into the y=mx+b and solve for b
<span>Website 1 : y = 1.50x + 30
website 2 : y = 2x + 0
y = 4x - 4
y = -4x + 4
4x - 4 = -4x + 4
4x + 4x = 4 + 4
8x = 8
x = 1
y = 4x - 4
y = 4(1) - 4
y = 4 - 4
y = 0</span>
