Triangle ABC has vertices A (6, 1), B (1, 7) and C ( -3, -2). The translation to create triangle A′B′C′ is (x, y) --> (x - 1, y + 2). Which of the following will be the coordinates of the vertices of triangle A′B′C′? A(5,2), (0, -4), (0,9)
B(5,3), (0, -4), (0,8)
C(5,3), (-4,0), (0,9)
D(5,2), (1, -3), (0,9)

What is the y-intercept of the line with the equation 3x + 4y = 12?

Anew obstacle course is home to several new types of challenging obstacles. one such obstacle is traversing a 15-stair staircase. to make it more challenging, the stairs are not uniformly spaced. rather, the vertical space between consecutive stairs for the first 10 stairs is 113 feet and the vertical space for the last 5 stairs is 134 feet. what is the total vertical distance traveled ascending and descending the entire 15-stair staircase?

Acomputer company is testing a new booster to increase program load times. the box plots show the number of seconds it takes to load a program with and without the booster. using these plots, how much did the median change?
