Answer:
[tex]-\frac{1}{2}[/tex]
Step-by-step explanation:
Here, the given expression,
[tex]-\frac{5}{6}x+7[/tex]
Put x = 9 in this expression,
[tex]=-\frac{5}{6}(9) + 7[/tex]
[tex]=-\frac{5(9)}{6} + 7[/tex] [tex]\because \frac{a}{b}\times c=\frac{ac}{b}[/tex]
[tex]=-\frac{45}{6}+7[/tex]
[tex]=\frac{-45+42}{6}[/tex] ( adding fractions )
[tex]=\frac{-3}{6}[/tex]
[tex]=-\frac{1}{2}[/tex]
