Answer:

  • m = -3/4
  • y-intercept = 399
  • slope-intercept equation: y = -3/4x + 399

Step-by-step explanation:

It can be easiest simply to solve the equation for y.

  3x + 4y = 1596

  4y = -3x + 1596 . . . . subtract 3x

  y = -3/4x + 399 . . . . divide by 4

From this equation in slope-intercept form you can read the slope as -3/4 and the y-intercept as 399. You already know the equation.

Answer:

26.25

Step-by-step explanation:

y=12

x=15

y=kx 12=k×15 k=12/15=4/5=0.8

A helicopter leaves central airport and flies north at 180 mi/hr. Twenty minutes later a plane leaves the airport and follows th
Pavel [41]

Answer:

Step-by-step explanation:

Let x represent the distance travelled by the helicopter and the plane.

Let t represent the time it takes the the helicopter to travel x miles

Speed of the helicopter is 180 miles per hour.

Distance travelled = speed × time

x = 180t

Twenty minutes later, a plane leaves the airport and follows the helicopter at 330mi/hr. Converting 20 minutes to hours, it becomes 20/60 minutes

Time taken for the plane to travel x miles is t - 20/60

x = 330(t - 20/60)

Before the plane overtakes the helicopter, they would have travelled equal distance. Therefore

330(t - 20/60) = 180t

330t - 110 = 180t

330t - 180t = 110

150t = 110

t = 110/150 = 0.73 hours
