Vinvika [58]

Answer:

A) $ \frac{1}{5} $

B) - 5

C) Not Possible

D) 5

E) $ \frac{-1}{5} $

  • Step-by-step explanation:
  • All integers are rational numbers. But not all rational numbers are integers.
  • All whole numbers are integers. But not all integers are whole numbers.

I am a rational number but not an integer. Located on the right of 0.

This means that it should be a positive number. Since, it is a rational number but not an integer, it should be of the form $ \frac{p}{q} $.

From, the options $ \frac{1}{5} $ would fit this description.

I am a rational number and an integer but not a whole number.

This means that it should be a negative integer. Since, all positive integers and zero would be whole numbers. From the options, the answer would be -5.

I am a whole number but not an integer.

This is clearly not possible because all whole numbers are a subset of integers.

I am a rational number, a whole number and an integer.

This means it is a positive integer. 5 would fit this description.

I am a rational number but not an integer; located on the left side of 0.

This means it is a negative number. $ -\frac{1}{5} $ should be the answer.

What is the remainder of (3x^4+2x^3-x^2+2x-14)/ (x+2)
Allisa [31]

Hi,

I assume the forward slash meant it as a fraction VS it being a division symbol. To answer your question, the remainder is 10.

Hope this helps.

What is the value of x in the equation 8 + 4 = 2 (x minus 1)?
satela [25.4K]

Answer:

x= 7

Step-by-step explanation:

The equation is 8+4= 2(x-1)

Distribute into the parenthesis.

8+4= 2x-2

Now, add.

12= 2x-2

Add 2 to both sides.

12= 2x-2

+2       +2

Then, divide by 2 to both sides to isolate the variable.

<u>14</u>= <u>2x</u>

2    2

x=7
