Acar traveled 36 miles in 45 minutes. the car traveled at a constant speed. if the car continues to
travel at this rate, which equation can be used to determine y, the total number of miles the car will
travel, in x hours?
a. y = 48x
by x +48
c. 48y mx
d. 48 + y = x

How many degrees does the hour hand move from 3: 00 to 5: 30?

Set $r$ is a set of rectangles such that (1) only the grid points shown here are used as vertices, (2) all sides are vertical or horizontal and (3) no two rectangles in the set are congruent. if $r$ contains the maximum possible number of rectangles given these conditions, what fraction of the rectangles in set $r$ are squares? express your answer as a common fraction.

Solve the system of equations. y=3x-1 and y=-2x+9. show work
