Evaluate the expression for u = 8.2. Write your answer in simplest form. u - 4/-u + 9 = ____

Substitute u = 8.2: Substitute u = 8.2 into the expression (u - 4)/(-u + 9). (u - 4)/(-u + 9) becomes (8.2 - 4)/(-8.2 + 9).Calculate numerator: Calculate the numerator 8.2 - 4. 8.2 - 4 = 4.2Calculate denominator: Calculate the denominator -8.2 + 9. -8.2 + 9 = 0.8Divide to simplify: Now we have 4.2/0.8. Divide 4.2 by 0.8 to simplify. 4.2 / 0.8 = 5.25

Q. Evaluate the expression for

u = 8.2

\newline

Write your answer in simplest form.

\newline

\frac{u - 4}{-u + 9} =

Substitute $u = 8.2$ : Substitute $u = 8.2$ into the expression $\frac{u - 4}{-u + 9}$ . $\newline$ $\frac{u - 4}{-u + 9}$ becomes $\frac{8.2 - 4}{-8.2 + 9}$ .
Calculate numerator: Calculate the numerator $8.2 - 4$ . $\newline$ $8.2 - 4 = 4.2$
Calculate denominator: Calculate the denominator \(-8. $2$ + $9$ ＂). $\newline$ \(-8. $2$ + $9$ = $0$ . $8$ ＂)
Divide to simplify: Now we have $4.2/0.8$ . Divide $4.2$ by $0.8$ to simplify. $4.2 / 0.8 = 5.25$
