A plane flying to Chicago begins its descent into O’Hare International airport. Once it starts, its height can be modeled by the equation h=-1200+33000, where h is its height in feet, and t is the time in minutes since it started its descent. What does the number 33000 represent in this situation?

Morgan's Mediterranean Restaurant has found that the number of falafel plates sold can be modeled by the equation �=1.3�+7.8 where �  represents the number of years since 2000, and �  represents the number of falafel plates sold, in thousands.   Predict the number of falafel plates the restaurant will sell in 2025.     Predict the number of falafel plates the restaurant will sell in 2040.

Jennifer is 19.6 miles north of her home. She boards an express train and continues traveling north at 60 miles per hour. Write an equation that shows how the number of miles Jennifer is from home, y, depends on the number of hours she is on the train, x.

During one month, the cost for renting a car in Mobile, Alabama was $68.22 per day plus 25 cents per mile. For a one day rental, let x denote the number of miles driven and let y denote the total cost, in dollars. Find the equation that expresses y in terms of x, find the total cost when car is driven 150 miles, and determine how many miles were driven if the cost of renting a car is $70.22.

A bacteria sample initially has 300 organisms. After 2 hours there are 500. Write an equation that will express the number present after t hours.

Morgan's Mediterranean Restaurant has found that the number of falafel plates sold can be modeled by the equation y = 1.3x + 9.3 where a represents the number of years since 2000, and y represents the number of falafel plates sold, in thousands. Predict the number of falafel plates the restaurant will sell in 2028. Predict the number of falafel plates the restaurant will sell in 2032.

use the Y axis to represent distance and the X axis to represent time. Four race cars are heading for the finish line. Car 11 is in the lead and has 1.2 miles to go.  But he has engine trouble and is only traveling at a speed of 130 mph.     How long before car 11 crosses the finish line (where distance remaining  = 0).                                                                 Car 32 is in second and is .1 miles behind Car 11 (he has 1.3 miles to go).    He is traveling at a speed of 140 mph.  Add that line to your graph. Car 53 is in third and is .3 miles behind the leader (1.5 miles to go).  He is traveling at a speed of 165 mph. Car 94 is in last place, and is .5 miles behind the leader (1.8 miles to go).   He is gaining fast, at a speed of 185 mph. Remember, the x axis is time, and the y axis is distance to go. The winner will be_______________________                                                   Second place will go to ____________________________…

The percentage of y college students in year x who work jobs while attending college can be approximated by the equation -0.34(x-1480)=19y-200.6. Find the year in which 72% of college students will work jobs while attending college.

Recently, a stock split and the value per share increased. Four days after the stock split, the stock was valued at $20 per share. Nineteen days after the stock split, the stock was valued at $65 per share. The equation 3x-y= -8 models the relationship between the stock's per share value y and the number of days x since the stock split.

A house is worth $125,000 when it is 2 years old and $135,150 when it is 7 years old. What is a formula, in slope-intercept form, that models this situation?
