Answer:

The pounds of beans that sells for $0.08 per pound used in the mixture is 22.9 and the pounds of beans that sells for $0.32 per pound used in the mixture is 87.1

Step-by-step explanation:

Let

x ----> pounds of beans that sells for $0.08 per pound

y ----> pounds of beans that sells for $0.32 per pound  

we know that

x+y=110 ----> equation A

0.08x+0.32y=0.27(110)

0.08x+0.32y=29.7 ----> equation B

Solve the system by graphing

The solution of the system of equations is the intersection point both graphs

using a graphing tool

The solution is the point (22,9,87.1)

The solution is reasonable

The pounds of beans that sells for $0.08 per pound used must be less than the pounds of beans that sells for $0.32 per pound, because the unit rate of $0.27 per pound is closer to the unit rate of $0.32 per pound

see the attached figure

therefore

The pounds of beans that sells for $0.08 per pound used in the mixture is 22.9 and the pounds of beans that sells for $0.32 per pound used in the mixture is 87.1

Does a trend line always pass through every point on a scatter plot?
forsale [732]
No, it does not and it's not supposed to.  A trend line is drawn to go through in the best way possible, to go through the "center" of the points as best as it can.  It may hit some of the points, but not all of them.  Generally, the idea is to try to get the trend line to have as many points "above" it as it does "below" it to say you've gone through them evenly.

When rewriting y = 2x + 1 in function notation, what do you replace with f(x)?
den301095 [7]

Answer:

You replace y with f(x)

Step-by-step explanation:

- Function is a relation between two sets of numbers, with every element

 in the first set has only one corresponding element in the second set

- The first set is called the domain of the function (input)

- The second set is called the range of the function (output)

- If the first set is set X and the second set is set of Y, then each value

 of x has only one value of y and x is the input and y is the output

- Function notation is the way to write a function f(x) = y, where f(x)

 represents the values of y

∵ y = 2x + 1

∵ f(x) = y

- Replace y by f(x)

∴ f(x) = 2x + 1

* <em>You replace y with f(x)</em>
