Answer:

A line parallel to the line y = x -4 would have a slope of 1.

A line perpendicular to the line y = x -4 would have a slope of -1.

Remember, parallel lines are lines that never intersect, which means that they cannot possibly have different slopes. A perpendicular line will always have the opposite slope as the first line, because the two lines must intersect at a 90 degree angle. The attached image shows how this works.

Hope this helps you out!

Find the volume of a cone with a base radius of 3 cm and a height of 9 cm

katovenus [111]

The volume of a cone is 84.78 cm

Step-by-step explanation:

Given:

radius = 3 cm and

height = 9 cm

To Find:

The Volume of a Cone

Formula:

The Formula for the volume of a cone is

V=πr2 *h/3

Solution:

V=πr2 *h/3

π value is 3.14

V= 3.14*(3)^2*9/3

V=3.14*9*3

V= 84.78 cm

Therefore the volume is 84.78 cm.

51.68 feet per hour. Convert this speed to inches per minute.

Lyrx [107]

Answer:

10.336.

Step-by-step explanation:

There are 12 inches in 1 foot so 51.68 ft/hr

= 51.68 * 12 in/hr.

Now there are 60 minutes in an hour so the speed in inches/minute

= 51.68 * 12 / 60

= 10.336.

5x + 2 = 8x + 5 Help me before I die quick math is so hardddddd

attashe74 [19]

Answer:

x = -1

Step-by-step explanation:

Note: when you send a number across it can change it sign. If it is positive it will turn negative.

5x + 2 = 8x + 5

Send 8x across

5x + 2 - 8x = 5

send 2 across

5x - 8x = 5 - 2

- 3x = 3

Divide both sides by - 3

- 3x/- 3 = 3/- 3

- 3 cancel out - 3

x = 3/ - 3

3 divided by - 3 is - 1

x = -1

he books in a private library are classified as fiction and nonfiction. There are 400 books in the library. There are 40 more fi

vfiekz [6]

First, you have to set a system of equations to determine the number of fiction and of nonfiction books.Call f the number of fiction books and n the number of nonfiction books. Then 400 = f + n. And f = n + 40 => n = f - 40 => 400 = f + f - 40 => 400 - 40 = 2f => f = 360 / 2 = 180. Now to find the probability of picking two fiction books, take into account the the Audrey will pick from 180 fiction books out of 400, and Ryan will pick from 179 fiction books out of 399, so the probability will be (180/ 400) * (179/399) = 0.20 (rounded to two decimals). Answer: 0.20
