CAN SOME ONE HELP ME ITS URGENT
aniked [119]

As we can observe from given information,

  • UT = ST

  • 2x + 5 = x + 12

  • 2x - x = 12 - 5

  • x = 7

now, let's solve for y

  • RU = RS

  • y - 4 = x + 5

  • y - 4 = 7 + 5

  • y = 12 + 4

  • y = 16

hope it helped...

The graph shows the distance, y, in miles, of a moving motorboat from an island for a certain amount of time, x, in hours:
lisabon 2012 [21]

Answer:  The speed of the motorboat is 70 miles per hour

Step-by-step explanation:  Subtract the initial distance, 35, from the distance at any given time, then divide the remainder by the hours.

For example, at 2 hours, the distance shown on the graph is 175 miles

Subtract: 175 -35 = 140.  Then divide 140/2 = 70

At 4 hours, the distance shown is 315 miles.

Subtract: 315 - 35 = 280. Then divide  280/4 = 70

70 mph is the speed.
