It's a rational number. 9 is a perfect square. What you have asked is written as -sqrt(9), which can be written as -sqrt(3*3) which is - 3. That's perfectly OK. What would not be OK is something like -sqrt(10) which is irrational because it cannot be represented as a fraction or a whole number or a repeating decimal or a decimal that terminates.

The negative square root of nine is neither rational or irrational.

The answer to this problem is 3i, which is an imaginary number. Imaginary numbers, by definition, are neither rational or irrational.

A line has a slope of 11 and passes through the point (2,4). ​ PLSS HELPP I NEED IT
Ivenika [448]

Answer:

y = 11x - 18

Step-by-step explanation:

Use the equation y = mx + b

m (the slope) = 11

x (the x-coordinate) = 2

y (the y-coordinate) = 4

Plug it in for our original equation:

4 = 11*2 + b

4 = 22 + b

4 - 22 = b

b = -18

Therefore, the answer is y = 11x - 18. The tricks to these problems are usually in the same format, when you are given the slope and a point it passes through, just plug in the slope and the x and y, and solve for b. Hope this helps!

Write two equivalent fractions for each. 1/2 and 4/5
Butoxors [25]
An equivalent fraction for 1/2 would be 2/4. This is because you can simplify 2/4 by dividing it by 2. The final answer would be 1/2.

An equivalent fraction for 4/5 would be 8/10. It's basically the same thing. Divide them both by 2 and you'll get 4/5 since 8 divided by 2 is 4, and 10 divided by 2 is 5.

Three sisters want to.Buy a pda for their fauther for fauthers day. The least expensive pda in the sorr isn$360. Writenand slove
zzz [600]

Answer:

$120

Step-by-step explanation:

I would like to rewrite your question for others easy to understand:

<em>"Three sisters want to Buy a pda for their father for fathers' day. The least expensive pda in the store  is $360. Writen and slove an inequality to fund the least amout of money each girl would have ti contrubute if each contribute an equal amount" </em>

<em />

Let X is the the amount one girl contribute, we have 3 girls => 3X

The least expensive pda in the store  is $360, so the total contributed amount must be equal or smaller than the pda cost

<=> 3X  \leq 360

<=> X \leq 120

So the least amout of money each girl would have to contrubute is $120
