Mathematics
1 answer:
Morgarella [4.7K]3 years ago

Answer:

r = 4

Step-by-step explanation:

If we clearly observe a point and the slope of the line are given.

Point=(5, -6)   slope= -5

We know that the equation of the line having slope m and passing through point (x_{1} , y_{1})  is

y-y_{1}=m(x-x_{1})

Now the equation of the line is y-(-6)=(-5)*(x-5)

y+6=-5x+25

5x+y=19

Now given that (3,r) lies on this line

5*3+r=19

r = 4

One plane can travel 30 miles per hour faster than another. one of them goes 185 miles in the same time it takes the other to go
ycow [4]
Plane #1 speed:  x mph
Plane #2 speed:  (x+30) mph

time = time becomes

170 mi        185 mi
---------- = --------------
      x             x+30

Solving for x, the speed of the slower plane, we get

170x + 5100 = 185 x
                                           5100
Then 15x = 5100, and x = ---------- (mi/hr) = 340 mph
                                              15

The slower plane flies at 340 mph, and the faster one at 370 mph.
