Answer:

5 4/9

Step-by-step explanation:

You can add in any order if it has the same denominator, so first you would add 2 1/9 + 3 5/9 to get 5 6/9. Lastly you would add 5 6/9 + (-2/9). Since it is negative you are subtracting -2/9 from 5 6/9 to get 5 4/9.

Add and Subtract Rational Expressions with a Common Denominator

Sladkaya [172]

Answer:

$\displaystyle \frac{4q^2-q+3}{q^2+6q+5}-\frac{3q^2-q-6}{q^2+6q+5}=\frac{q^2+9}{q^2+6q+5}$

Step-by-step explanation:

Simplifying Rational Expressions

If two or more rational expressions have the same denominator, the add and subtract operations are done only with the numerator. The final denominator will be the common of both.

The expression is:

$\displaystyle \frac{4q^2-q+3}{q^2+6q+5}-\frac{3q^2-q-6}{q^2+6q+5}$

Operating on the numerators:

$\displaystyle \frac{4q^2-q+3}{q^2+6q+5}-\frac{3q^2-q-6}{q^2+6q+5}=\frac{4q^2-q+3-(3q^2-q-6)}{q^2+6q+5}$

Removing parentheses:

$\displaystyle \frac{4q^2-q+3}{q^2+6q+5}-\frac{3q^2-q-6}{q^2+6q+5}=\frac{4q^2-q+3-3q^2+q+6}{q^2+6q+5}$

Simplifying:

$\boxed{\displaystyle \frac{4q^2-q+3}{q^2+6q+5}-\frac{3q^2-q-6}{q^2+6q+5}=\frac{q^2+9}{q^2+6q+5}}$

The expression cannot be further simplified.

8) What is the domain of the function? Please help

alisha [4.7K]

Answer:

{ x | 1, 2, 3, 4, 5, 6, 7, 8, 9 }

Step-by-step explanation:

We note that points between integer values have been excluded, so domain consists of integer x-values from 1 to 9, or

{ x | 1, 2, 3, 4, 5, 6, 7, 8, 9 }

and not

1 <= x <= 9
