Evaluate the expression for u = 4. Write your answer in simplest form. u - 10/-u - 5 = ____

Substitute u = 4: Substitute u = 4 into the expression (u - 10)/(-u - 5). Expression after substitution: (4 - 10)/(-4 - 5)Simplify numerator and denominator: Simplify the numerator and the denominator. Simplify the numerator: 4 - 10 = -6 Simplify the denominator: -4 - 5 = -9 Expression becomes: (-6)/(-9)Simplify fraction: Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 3. (-6)/(-9) = (6/9) after removing the negative sign from both the numerator and the denominator. Now divide both by 3: (6/3)/(9/3) = 2/3

Q. Evaluate the expression for

u = 4

\newline

Write your answer in simplest form.

\newline

\frac{u - 10}{-u - 5} =

Substitute $u = 4$ : Substitute $u = 4$ into the expression $\frac{u - 10}{-u - 5}$ . $\newline$ Expression after substitution: $\frac{4 - 10}{-4 - 5}$
Simplify numerator and denominator: Simplify the numerator and the denominator. $\newline$ Simplify the numerator: $4 - 10 = -6$ $\newline$ Simplify the denominator: $-4 - 5 = -9$ $\newline$ Expression becomes: $(-6)/(-9)$
Simplify fraction: Simplify the fraction by dividing both the numerator and the denominator by their greatest common divisor, which is $3$ .
$(-6)/(-9) = (6/9)$ after removing the negative sign from both the numerator and the denominator.
Now divide both by $3$ : $(6/3)/(9/3) = 2/3$
