Aplane set off to burbank at a speed of 215 mph. on the return flight of 13 hours, the plane cruised at 237 mph. how many hours was the flight to burbank? i just need the equation

It seems you need 2 equations:

We first must solve for: distance = rate * time  

Using return flight data:   distance = 237 * 13 = 3,081 miles

Then, using flight TO Burbank data: time = distance / rate

time = 3,081 / 215   time = 14.3302325581 hours

y= 2x+7

changed to y= 5x +7

as slope is increased from 2 to 5

therefore it would be less steeper

so, option d) is correct

none of these

step-by-step explanation:

23 + 34 add up to 57 so just inform the teacher of this really stupid mistake
