The population of jose’s town in 1995 was 2400 and the population in 2000 was

4000. let x represent the number of years since 1995. write a linear equation, in slope-

intercept form, that represents this data.

Step-by-step explanation:

Remember, a line has the form , where is the slope and is the y-intercept. In this cases, y represents the population when have been passed x years since 1995.

Since x represent the number of years since 1995, then in 1995, x=0 and the population is 2400. Then a point of the linear equation is (x,y)=(0,2400).

In 2000 has been passes 5 years since 1995 and the population is 4000, this means that x=5 and y=4000. Then other point in the line is (x,y)=(5,4000)

For find the equation of the line that describe the preview situation we use the points found.

Remember, if and are pointsin the plane, the slope of the line that passes through the points is

, and the line is of the form

Then, using the points (0,2400),(5,4000), we have that

and

$47.66

Step-by-step explanation:

The cost of the sweater is calculated by multiplying .7 x $35. (70% represents the cost of the sweater since there is a 30% discount.). The sweater cost $24.50.

The cost of the jeans is .85 x $28 = $23.80.

The total cost is $24.50 + $23.80 = $43.80.

The tax rate is 8%, which is calculated by multiplying .08 x $43.80 = $3.86 in sales tax.

Including the sales tax, the total cost is $43.80 + 3.86 = $47.66
