Question

Find the value of y, if the distance between the points (2,y) and (−4,3) is 50

Answer 1

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
