Astore offers packing and mailing services to customers. this table is given to customers to them estimate the cost of shipping a box based on its weight in pounds, and a flat rate of $5 for packing. which equation represents the shipping cost as a function of x, the weight in pounds? a. f(x) = 2.25x + 5. b. f(x) = 3.5x + 4. c. f(x) = 4x + 9. d. f(x) = 9x + 14

Step-by-step explanation:

A.f(x) = 2.25x + 5

f(x) = 2.25x + 5

Step-by-step explanation:

As given, the cost of shipping a box is based on its weight in pounds, and a flat rate of $5 for packing. This means $5 is common for each parcel that will be sent. Only the weight will vary.

So, option first f(x)=2.25x+5 is the correct answer. Here 2.25 is the per pound rate. Like if someone wants to send a parcel weighing 3 pounds, the price will be :

f(x)=2.25*3 +5

= $11.75

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

d) 30 units^2

area of rectangle = l × b

we know,

length = 10 unit

breadth = 3 unit

applying the formula,

= l × b

= 10 × 3

= 30 unit^2
