Sales of hybrid (gas-electric) vehicles have been decreasing for the past few years. In 2007, 385 thousand new gasoline-electric hybrid vehicles were sold in a country. In 2010, only 295 thousand were sold. a. Assume that the relationship between time, x, and the number of thousands of registered "gasoline-electric hybrid" vehicles, y, is linear. Write an equation describing the relationship between time and the number of thousands of registered "gasoline-electric hybrid" vehicles sold. Use ordered pairs of the form (years past 2007, number of thousands of hybrids sold). The equation is. (Type your answer in slope-intercept form.)

A $27,000 car has a resale value of $19,000 five years after it was purchased. Assuming the value of this car depreciates linearly, estimate the value of the car 8 years after it was purchased. Enter number only; if your answer is $12,345, enter 12345.

According to the data from public health units, Canada has begun its largest mass vaccination program in history. On the 10th day from the start of the vaccination program, there were 706 thousand vaccination doses administered. On the 17th day, there were 937 thousand vaccination doses administered. Assume that the number of vaccination doses administered keeps growing in a linear manner. a) What is the equation that gives the number of vaccination doses administered in Canada in terms of the number of days since the vaccination program started? b) What is the estimated number of vaccination doses administered by the 30th day since the vaccination program started? (Use the equation from part (a)) c) How many days since the beginning of the vaccination program will take to administer 1696 thousand vaccination doses in Canada? (Use the equation from part (a))

Write a linear equation in slope-intercept form that models each scenario.  State what y, m, x, and b represent for each scenario.Connor has $25,000 in his bank account.   Every month he spends $1,500.  He does not add money to the account.

Suppose that the number of tee shirts sold (N) depends linearly on the price charged (x). Write an equation showing this dependence.
