Answer 1

I hope this helps you

Answer 2

Answer:  The required value of h(-9) is -12.

Step-by-step explanation:  We are given the following function :

$h(r)=\dfrac{2}{3}r-6~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~(i)$

We are to find the value of h(-9).

To find the value of h(-9), we need to substitute r = -9 in equation (i).

From equation (i), we get

$h(-9)\\\\=\dfrac{2}{3}\times(-9)-6\\\\\\=2\times(-3)-6\\\\=-6-6\\\\=-12.$

Thus, the required value of h(-9) is -12.
