3. Hi Graph the data in the table below. Which kind of function best models the data? Write an equation to model the data.

x y

0 -6
1 -9
2 -12
3 -15
4 -18

A. exponential; y = –6•1.5x

B. quadratic; y = –x2 – 2x

C. quadratic; y = –x2 + 2x – 6

D. linear; y = – 3x –6

Given the system of equations presented here: 2x + 4y = 14 4x + y = 20 which of the following actions creates an equivalent system such that, when combined with the other equation, one of the variables is eliminated? multiply the second equation by â’4 to get â’16x â’ 4y = â’80 multiply the second equation by â’1 to get â’4x â’ y = â’20 multiply the first equation by 2 to get 4x + 8y = 28 multiply the first equation by â’1 to get â’2x â’ 4y = â’14

The mean average cost of standard room per night at a hostel is ? 20.60. therefore, how much does a standard room cost per night at night-time rest days?

The room above is shaped like a rectangle anthe room above is shaped like a rectangle and has a perimeter of 34 feet. if the room is 11 feet long, how wide is it?
