Provide an example of an integer that is not a whole number
kramer

Answer:

-5

Step-by-step explanation:

The integers are ..., -4, -3, -2, -1, 0, 1, 2, 3, 4, ... -- all the whole numbers and their opposites (the positive whole numbers, the negative whole numbers, and zero). Fractions and decimals are not integers. All whole numbers are integers (and all natural numbers are integers), but not all integers are whole numbers or natural numbers. For example, -5 is an integer but not a whole number or a natural number.

Find the value of the variable y, where the sum of the fraction 2/y-3 and 6/y+3 is equal to the quotient.
NISA [10]

Answer:

Here we need to solve:

\frac{2}{y - 3}  + \frac{6}{y + 3 }  = \frac{\frac{2}{y-3}}{\frac{6}{y + 3} }

The sum of the fractions is equal to the quotient between the fractions.

Notice that the two values:

y = 3

y = -3

make the denominator equal to zero, so those values are restricted.

We can simplify the right side to get:

\frac{2}{y - 3}  + \frac{6}{y + 3 }  = \frac{\frac{2}{y-3}}{\frac{6}{y + 3} } = \frac{2*(y + 3)}{6*(y - 3)}  = 3*\frac{y + 3}{y - 3}

Now we can multiply both sides by (y - 3)

(y - 3)*(\frac{2}{y - 3}  + \frac{6}{y + 3 }) = 3*(y + 3)\\2 + 6*\frac{y -3}{y + 3} = 3*(y + 3)

Now we can multiply both sides by (y + 3)

(2 + 6*\frac{y -3}{y + 3})*(y + 3) = 3*(y + 3)*(y + 3)

2*(y + 3) + 6*(y - 3) = 3*(y + 3)*(y + 3)\\\\2*y + 6 + 6*y - 18 = 3*(y^2 + 2*y*3 + 9)\\\\8*y - 12 = 3*y^2 + 6*y + 33\\\\0 = 3*y^2 + 6*y + 33 - 8*y + 12\\\\0 = 3*y^2 - 2*y + 45

First, let's see the determinant of that quadratic equation:

D = (-2)^2 - 4*3*45 = -536

We can see that it is negative, thus, there are no real solutions of the equation.

Thus, there is no value of y such that the origina equation is true,
