at store A, pencils are sold on individually. The cost y of x pencils is represented by the equation y = 0.55x. The costs of pen

Helga [31]

Answer:

The pencils at store A cost more

Step-by-step explanation:

The complete question in the attached figure

store A

we have

$y=0.55x$

This is a proportional relationship between the total cost (y) and the number of pencils (x)

The constant of proportionality is equal to the slope

The slope or unit rate is equal to

$m=\$0.55\ per\ pencil$

Store B

This is a proportional relationship between the total cost (y) and the number of pencils (x)

The constant of proportionality or slope is equal to

$k=\frac{y}{x}$

For (6,3.06)

substitute

$k=\frac{3.06}{6}$

$m=\$0.51\ per\ pencil$

The linear equation at store B is

$y=0.51x$

<u><em>Verify each statement</em></u>

case 1) The pencils at store A cost more

The statement is true

Because, one pencil at store A cost $0.55 and one pencil at store B cost $0.51

case 2) The pencils at store A cost $0.27 each

The statement is false

Because, one pencil at store A cost $0.55

case 3) The pencils at store B cost $0.30 each

The statement is false

Because, one pencil at store B cost $0.51

case 4) The pencils at store B cost more

The statement is false

Because, pencils at store A cost more

In the function f(x) = a(x + 2)(x-3)^b, a and b are both

Gekata [30.6K]

Using limits, considering the end behavior of the function f(x), it is found that the correct statement is given as follows:

D. a is positive, and b is odd.

<h3>What is the end behavior of a function?</h3>

It is given by it's limits as x goes to negative and positive infinity.

In this problem, we have that, considering the end behavior:

$\lim_{x \rightarrow \infty} = \infty \rightarrow ax^{b + 1} = \infty$

$\lim_{x \rightarrow -\infty} = \infty \rightarrow ax^{b + 1} = \infty$

This will only be true if a is positive and b is odd, hence option D is correct.
