7 0

Answer:

7, -5, 2/3, 5.79

Step-by-step explanation:

rational numbers are numbers you can put in fraction form. \sqrt{13} is not a perfect square, therefore you cannot put it in fraction form. \sqrt{-4} is an imaginary number. Rational numbers are in the Real Numbers category, so it is not a rational number.

3.3w - 9 &gt; - 22. <br><br> I need this for plz a need it like right now
Darina [25.2K]

Answer:

w > - 3.94

Step-by-step explanation:

We have to solve a linear single variable equation of inequality of w.

The inequality is  

3.3w - 9 > - 22

⇒ 3.3w - 9 + 9 > - 22 + 9 {Adding both side with 9}

⇒ 3.3w > - 22 + 9

⇒ 3.3w > - 13

⇒ \frac{3.3w}{3.3}  > - \frac{13}{3.3}

⇒ w > - \frac{13}{3.3} {Dividing both sides by 3.3}

⇒ w > - 3.94 (Approximate) (Answer)

Which equation models the relationship between the two variables in the table below?
Lilit [14]

Answer:

The answer is "\bold{y=9^x}"

Step-by-step explanation:

In the given question some information is missing that is table attachment. In this table there are many element is defined, which can be given as follows:

x = -1 \  \ \ \ y = 0.111\\x =1 \ \ \ \ \ \  y = 9\\x =2 \ \ \ \ \ \ y = 81\\x =4 \ \ \ \ \ \ y = 6,561\\ x =5 \ \ \ \ \ \ y = 59,049\\

Now check the value:

y = x^9, \   x = -1,  and \ y = (-1)^9 = -1 \ it \ is \ wrong.\\ y= 9x^2   \ gives \ value \ -9 \ that \ is\ wrong \ and  \\\\ \ when \ \ x= 1 \\\\ y= 9^x   \\ y= 9^1 \\y= 9 \ gives \ the \ correct \ value.
