Can I have some help please? A company ships packages through the postal service. One week, the cost of shipping one package was $6.70, and the company also purchased x number of stamps. This can be modeled by the expression 6.70+0.50x. According to the model, what is the meaning of 0.50?

number of packages shipped

number of stamps purchased

cost of shipping one package

cost of one stamp

sorry i need the points

provide more details to solve it

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.

time is equal to distance over rate so

t = d/r

need a little bit more information for the second question.
