Answer:

-1, 0, 1, 2, 3

Step-by-step explanation:

To answer this you have to understand 2 main things

These are: the symbols and what an integer is.

An integer is simply a whole number. For example: 1, 10, 3 etc.

The symbols, <= (first symbol) and < (second symbol) are very important. These tell us the range X is in.

<= means less than or equal to.

< means less than.

So we can write: -1 is less than or equal to x and x is less than 4.

If we follow this and also keep in mind we only want whole numbers then we can see the lowest X can be is -1 and the highest it can be is 3 since it has to be less than 4.

Then it is also everything inbetween them which is:

-1, 0, 1, 2, 3

what is the volume, in cubic centimeters, of a cylinder that has a height of 15 cm and a diameter of 12cm?

Allisa [31]

Answer:

<h2>Option 2</h2>

$540\pi$

Step-by-step explanation:

Given, 

Diameter of the cylinder = 12cm

Radius of the cylinder = 12cm ÷ 2 = 6cm

Height of the cylinder = 15cm

Therefore, 

Volume of the cylinder

$= \pi {r}^{2} h$

$= \pi \times 6 \times 6 \times 15 {cm}^{3}$

$= 540\pi \: cubic \: cm$

Hence,

Option 2 is correct for volume of the cylinder in cubic cm:

 $540\pi$

Find the equation of a line that passes through the point (4,2) that is perpendicular to the line y = x. Show your work.

maria [59]

If it has to be perpedicular to y = x, then the slope has to be -1/x because perpedicular slope is the opposite reciprocal. Now plug what you know into the point slope formula.

y - 2 = -1/1 (x - 4)

***** Since -1/1 is the same as -1, it can be rewritten as -1. ****************

y - 2 = -1 (x - 4)

Now distribute -1 times x and -4.

y - 2 = -x + 4

Add 2 to both sides to get y by itself.

y = -x + 2

Your answer should be:

y = -x + 2
