Which of these points lies on the line described by the equation below y-3=5(x-9)
ladessa [460]

Answer:

(9,3)

Step-by-step explanation:

We have been given an equation of a line y-3=5(x-9) and we are asked to find the point that lies on our given line.

Since we know that point-slope form equation of a line is: (y-y_1)=m(x-x_1), where,

m = The slope of the line.  

(x_1,y_1) = The coordinates of given point on the line.

Since our given equation is in point-slope form, so x-coordinate of our given point is 9 and y-coordinate of our given point is 3.

Therefore, point (9,3) lies on the line described by our given equation.

A) Model this situation with a linear system:
sergejj [24]

Answer:

The daily rate is $ 29 and the fee for each kilometer driven is $ 0.35.

Step-by-step explanation:

Since to rent a car, a person is charged a daily rate and a fee for each kilometer driven, and when Chena rented a car for 6 days and drove 320 km, the charge was $ 286.00, while when she rented the same car for 10 days and drove 900 km, the charge was $ 605.00, to determine the daily rate and the fee for each kilometer driven the following calculation must be performed:

286 = 6 days and 320 km

320/6 = 53,333 km

286/6 = $ 47,666

Thus, the value of 1 day and 53,333 km is $ 47,666.

605 = 10 days and 900 km

900/10 = 90 km

605/10 = $ 60.5

Thus, the value of 1 day and 90 km is $ 60.5.

90 - 53,333 = 36,666

60.5 - 47.666 = 12.833

12,833 / 36,666 = value per kilometer traveled

0.35 = value per kilometer traveled

(286 - (0.35 x 320)) / 6 = X

(286/112) / 6 = X

174/6 = X

29 = X

(605 - (0.35 x 900)) / 10 = X

(605 - 315) / 10 = X

290/10 = X

29 = X

Therefore, the daily rate is $ 29 and the fee for each kilometer driven is $ 0.35.
