Step-by-step explanation:
Down 2 units : we will move the point 2 units to the down direction of the vertical line (y-axis)
which means (x ,y-2) = (-2,1)
right 3 units = we will move the point 3 units to the right direction of the horizontal line (x axis )
(x+3,y)= (1,3)
up 1 unit and left 4 units : we will move the point 1 unit in the up direction of the vertical line (y-axis)
and move it 4 units in the left direction of the horizontal line (x axis )
(x-4,y+1l. = (-6,4)
The answer is a.
eliminate c and b because that's wrong then identify the dependent quantity.
It would take 2.61 hours to fly from Dallas to Boston at 775 mph.
Since the time it takes to fly from Dallas to Boston varies inversely with the speed of the plane, to determine, if the trip takes 4.75 hours at 427 mi / h, how long would it take at 775 mi / h, the following calculation must be performed:
- (427 x 4.75) / 775 = X
- 2028.25 / 775 = X
- 2.61 = X
Therefore, it would take 2.61 hours to fly from Dallas to Boston at 775 mph.
