Answers

Answer 1
Answer:

Answer: The relation between p, the weight of a package, and c, the cost of shipping it is given by

Step-by-step explanation:

Let the weight of a package be 'p'.

Let the cost of shipping be 'c'.

Cost of postage per pound = $1.80

Cost for prepare a package for shipping = $16

According to question,

Hence, the relation between p, the weight of a package, and c, the cost of shipping it is given by

Answer 2
Answer: T (total cost)=p (lbs) * postage + 16$

If x=0 what is the slope of the line?

Answers

The slope of your line would be undefined since your line is just going straight up. The reason for this is while your y value is changing, your x value is always staying the same, meaning your line will just be traveling straight up.

What is an Algebraic Expression?

An algebraic expression in mathematics is an expression which is made up of variables and constants, along with algebraic operations (addition, subtraction, etc.).

According to question, we have - The perimeter of the square with side length y.

The formula for the perimeter of square = 4 x sides.

The perimeter of the square with side length y can be written as = 4y.

In this expression -   y is a variable, 4 is the coefficient of y.

We have -

P = 4y

Simplifying, we get -

y =

Hence, the statement in the expression form is -  f(y) =  4y and on simplifying it we get -  y = .

What is arithmetic progression?

A progression of numbers known as an arithmetic sequence is one in which, for every pair of consecutive terms, the second number is derived by adding a predetermined number to the first one.

Given sequence  -2, 1, 4, 7, 10,...

since the sequence is in AP,

where a₁ = -2

d = difference of two consecutive terms

d = a₂ - a₁ =  1 - (-2)

d = 3

the formula for n terms is given by

aₙ = a₁ + ( n - 1)d

substitute the values

aₙ = -2 + (n - 1)3

aₙ = -2 + 3n - 3

aₙ = 3n - 5

Hence the equation is aₙ = 3n - 5.
