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:

Answer/Step-by-step explanation:

In the situation explained in the question, the cost of shipping is dependent on the weight of the box to be shipped.

For a box of 4 pounds, total shopping cost (x) => $15 (y)

For a box of 8 pounds (x), total shopping cost => $23 (y)

Therefore:

a. The input is weight of box

b. The output is cost of shipping

c. Using the 2 given pair (4, 15) and (8, 23), slope is calculate using the formula below:

Slope = 2

d. The slope represents the amount charged per pound of weight. That is, $2 per pound.

e. Let's derive an equation to represent the situation using the slope-intercept formula given as y = mx + b

y = total cost of shipping

x = weight of box

m = average cost per pound = slope

b = y-intercept = flat fee charged for shipping before adding the cost of weight per pound

Substitute x = 4, y = 15, m = 2 into y = mx + b, and solve for b

15 = 2(4) + b

15 = 8 + b

15 - 8 = b

7 = b

b = 7

The equation would be y = 2x + 7

The y-intercept = 7

f. The y-intercept, 7, is the starting amount, that is the flat fee charged before the cost per pound of weight of a box is added to give total cost of shipping.

this question has already been answered so im just swooping in to grab the points but the other guy answered so mark him brainliest

Step-by-step explanation:

answer: c i think

step-by-step explanation:

answer rather than having to add and subtract the measurements of the semi-circle, notice that the semicircle to the left of ad is actually identical in area to the blank semicircle-shaped space to the left of bc. so if we transferred the red semicircle into the blank space, we would end up with a square of side length 24 cm. the area of a square is s^2 = 24^2 = 676 cm^2.

u also answered this so i think u would know but i am here to
