Darrin can skateboard 2 miles against a 4 mph wind in the same amount of time he skateboards 6 miles with a 4 mph wind. Find the
MA_775_DIABLO [31]

Answer:

Speed = 8mph

Step-by-step explanation:

Speed of wind = 4mph

Let speed of Darrin with no wind be "x" mph

then resultant speed of Darrin, travelling in direction of wind = (x + 4) mph

Using a result, Time = Distance travelled / Net speed

Time taken by Darrin to travel 6miles in direction of wind = 6 / (x + 4)

When Darrin travel in opposite direction of wind, then its net speed                                                  = (x - 4)mph

Darrin travel 2 miles against the wind in 6/(x + 4) hr

then   Distance =  speed ×  time

           2 =  ( x- 4 ) × ( 6/x + 4)

          2x + 8 = 6x - 24

            4x  =  32

              x = 8 mph

Therefore speed of Darrin skateboard with no wind = 8mph

Answer: because the figure on the left is negative and more wide open while the other one is not only smaller but also positive and it’s more shut

Step-by-step explanation:

So the X-axis of the Figure on the left is going form point -3 to 0 while the other figure on the right is going form 3 to 5. And the Y- axis of the figure on the left is 2 while the right is 1 which proves that the figure on the left is bigger then the other

Your Also supposed to add all the point like first look for the Y and the X of I with J Then look for H and K then look for G and L the look for the slope of all those and then add them,then do the same with the left one and see which ones more and how much more
