Answer:

y= -5/3 x - 6

Step-by-step explanation:

3x-5y=20

-5y=20-3x

y= (3/5)x - 5

3/5 is the slope

a perpendicular line's slope is the opposite reciprocal

-5/3 = m

y-y1=m(x-x1)

(-6, 4) = (x1, y1)

plug in the values

y-4= -(5/3) (x+6)

y-4= -5/3 x - 10

y= -5/3 x - 6

Paha777 [63]

Answer:

the amount of space present is 15,120 cubic inches

Step-by-step explanation:

To get the amount of space, we simply calculate the volume of the space

This is the area of the base multiplied by the length

Mathematically, we have this as;

Area of the triangle multiplied by the length of the cabinet

We have this as;

(1/2 * 20 * 21) * 72

= 210 * 72

= 15,120 cubic inches

Answer:

  • Tyler
  • 2 hundredths of a mile

Step-by-step explanation:

The graph is a little difficult to read, but we note that there are 6 grid lines between times that are 2 minutes apart. So, each grid line stands for 2/6 = 1/3 minute.

At the 1-mile mark, the graph crosses 1 grid line above 8 minutes, indicating it takes Tyler 8 1/3 minutes to run 1 mile.

Then in 10 minutes, Tyler will run ...

  distance = speed · time = 1 mile/(8 1/3 min) · 10 min

  = 1/(25/3)·10 = 10·3/25 = 30/25 = 1.2 . . . . miles

__

The equation tells you that Elena runs each mile in 8.5 minutes. To see how far she runs in 10 minutes, we can solve ...

  10 = 8.5x

  x = 10/8.5 ≈ 1.18 . . . . miles

So, Tyler runs farther in 10 minutes by a distance of ...

  1.20 -1.18 = 0.02 . . . . miles
