4. A store offers packing and mailing services to customers. If a customer ships a box weighing 4 pounds, it would cost $15. If a customer ships a box weighing 8 pounds, it would cost $23. Identify the following characteristics: a. What is the input? b. What is the output? c. What is the slope? Show your work. d. What does the slope represent in words? e. What is the y-intercept? Show your work. f. What does the y-intercept represent in words?

(- 1, 0 )

step-by-step explanation:

an x- intercept is where the function crosses the x- axis.

to find the x- intercept/s look for the value of x when f(x) = 0

from the given table there are 3 values of x where f(x) = 0

when x = - 1, x = 2, x = 3

the one that is listed is (- 1, 0 )

c. 27 units.

step-by-step explanation:

we are told that in circle a, ∠bae ≅ ∠dae.

we can see from our given diagram that in and ;

, as these are radii of our given circle.

therefore, by sas congruence postulate.

hence, side be will be equal to side de as corresponding parts of congruent triangles are congruent. so we can set an equation to find the value of x as:

now let us substitute x=17 in the expression for the length of be.

therefore, length of be will be 27 units and option c is the correct choice.
