Answer:
x in (-oo:+oo)
Y = (6/13)*x // - (6/13)*x
Y-((6/13)*x) = 0
Y+(-6/13)*x = 0
Y-6/13*x = 0 // - Y
-6/13*x = -Y // : -6/13
x = -Y/(-6/13)
x = 13/6*Y
x = 13/6*Y
Answer:
Step-by-step explanation:
Bag A contains 9(5/9) pounds of coffee
Bag B contains 9(2/3) pounds of coffee
Which bag contains less coffee?
( 2/3) is the same as (6/9)
Now that the denominators are the same, if we compare the numerators, 5 is less than 6 (5 parts of 9 is less than 6 parts of 9)
Bag A contains less coffee than bag B
9(5/9) < 9(2/3)
A) 0.73
B) 21.93
C) 7.67
5&5-----------5
10&14------------2
20&36-----------2
This is the volume of the sphere & is not at all a linear function.
A linear function of the form of y=kx (k is a given number/coefficient) where
y & x grow at the same rate. Then whatever the input (x) it will generate an output (y) always in the ration y/x, whereas v=4/3 πr³ (coefficient =k =4/3(π), if r increase by 2 units v will increase by 2³ =8 & for r = 3, v increase by 3³ =27.
In short v increases quicker than r. No it's not a linear function
So to start this question you find the prices of the two types of cups and create a basic formula for them. For the mug it would have a base price of $2.95 and a refill price of $0.50. For the disposable cup it would cost $0.85 a piece.
So for the mug you would take the base price of 2.95 and add it by x amount of refills to find the break even point of the two. So the formula would look like 2.95+0.50x. The other would be 0.85x. Now its just a matter of guess and check to see how many refills it would take for the mug to be cheaper. i hope this helped!
