Answer:
[tex]h(-9)=-\frac{2}{33}[/tex]
Step-by-step explanation:
The given expression is [tex]h(r)=\frac{2}{3r-6}[/tex]
We want to find the value of h(-9).
We substitute r=-9 to obtain:
[tex]h(-9)=\frac{2}{3(-9)-6}[/tex]
We multiply out to obtain:
[tex]h(-9)=\frac{2}{-27-6}[/tex]
We simplify the denominator to obtain:
[tex]h(-9)=\frac{2}{-33}[/tex]
This is the same as:
[tex]h(-9)=-\frac{2}{33}[/tex]
