Two trains leave the station at the same time going in opposite directions. one of the trains travels at 90 mph and the other is traveling at 120 mph. after how many hours will they be 735 miles apart?

Find the equation of the line that goes through the points (4, –1) and (2, –5). use slope formula,equation,to find the slope of a line that passes through the points. m = use slope-intercept form, y = mx + b, to find the y-intercept (b) of the line. b = write the equation in slope-intercept form, y = mx + b.

If the ratio of sum of the first m and n terms of an ap is m2 : n2 , show that the ratio of its mth and nth terms is (2m − 1) : (2n − 1).

Which number completes the inequality? 2/3 < _ < 7/9
