Which statement about f(x) = 2x 2 - 3x -5 is true?

The zeros are -1 and 5 / 2 , because f(x) =(x + 1) (2x - 5).

The zeros are - 5 / 2 and -1, because f(x) =(x + 1) (2x + 5).

The zeros are - 5 / 2 and 1, because f(x) =(x - 1) (2x + 5).

The zeros are 1 and 5 / 2 , because f(x) =(x - 1) (2x - 5).

A student rode a bike from school to a recreation center. The graph shows the student’s distance in miles from the recreation center after riding the bike for x minutes. What is the range of the function for this situation?

All real numbers greater than or equal to 0 and less than or equal to 9

All real numbers greater than or equal to 0 and less than or equal to 28

All real numbers less than or equal to 28

All real numbers less than or equal to 9

A bag contains 18 coins consisting of quarters and dimes. The total value of the coins is $2.85. Which system of equations can be used to determine the number of quarters, q , and the number of dimes, d , in the bag?

0.25q + 0.10d = 2.85 q + d = 18

0.10q + 0.25d = 2.85 q + d = 18

0.10q + 0.25d = 18 q + d = 2.85

0.25q + 0.10d = 18 q + d = 2.85

The coffee company opened 100 stores in one year.

Every year the number of store the coffee company opened increased by 25%.

Since 1992 the coffee company has opened 250 stores each year.
