Question

Find the value oh h(45) for the function h(x) = 1/9(90-x)

Answer 1

Answer: B. h(45) = 5

Explanation:

To find h(45), we will substitute 45 for x into the original function.

`\displaystyle h(x)= (1)/(9)(90 -x)`

`\displaystyle h(45)= (1)/(9)(90 -45)`

Now, we will subtract.

`\displaystyle h(45)= (1)/(9)(45)`

Lastly, we will multiply. Since we are multiplying by one-ninth, we can divide 45 by 9.

`\displaystyle h(45)= 5`
