To which subset of real numbers does -18 not belong?

1 answer:

3 0

The subsets of the real numbers are the irrational numbers, rational numbers, integers, whole numbers, and the natural numbers. First, figure out where does -18 belong? Well, -18 is a rational number because it can be expressed as a fraction of two integers. It's also an integer.

So, it doesn't belong in the sets of irrational numbers, whole numbers, and the natural numbers.

What is the answer

Finger [1]

Answer:

Step-by-step explanation:

1. One large bottle is equal to small bottle+4$

2. 8 large bottles (= 8 small bottles + 32$) cost 24$ less than 12 small bottles. Replacing large bottles with small bottles+4$, we have 8b+32=12b-24 -> Simplifying 4b=8, b=2$ Where b is small bottle.

You have 500 sheets of notebook paper. After 1 week, you have 72% of the sheets left. You use the same number of sheets each wee

NISA [10]

You use 28% of your available sheets
28% = .28
500 x .28 = 140 sheets used

(0,500) (1,360)

m = 360-500/1-0
m = -140

y = -140x + 500

How do you graph a circle x^2 + y^2=25 and the line is given y=2

Kazeer [188]

$\bf \textit{equation of a circle}\\\\ 
(x-{{ h}})^2+(y-{{ k}})^2={{ r}}^2
\qquad 
\begin{array}{lllll}
center\ (&{{ h}},&{{ k}})\qquad 
radius=&{{ r}}
\end{array}\\\\
-------------------------------\\\\
x^2+y^2=25\implies (x-0)^2+(y-0)^2=5^2$

so notice above, the circle is centered at h,k or 0,0, the origin, and has a ratio of 5.

and y = 2, is just a horizontal line, check the picture below.
