Question

5g - 7 for g = 9 I’m trying to Evaluate the algebraic expression

Answer 1

The value of the expression when g = 9 is
`\boxed{\bf 38}`.

Explanation:

Given algebraic expression:-

`5g - 7`

We need to evaluate this expression.

When ,

`g = 9`

Solution:-

`\sf = 5g - 7`

Put the value of g [ 9 ] on the given expression :-

We know that g is multiplied with 5 on this expression.

So,9[Value of g which is given] is also be multiplied by 5 on this expression.

`\sf = 5 * 9 - 7`

Now Simplify :-

Multiply 5 and 9 :-

`\sf = 45 - 7`

Subtract :-

`\sf = 38`

We are done!

Hence the value of the expression when g = 9 would be ;

`\boxed{\tt38}`

`\rule{225pt}{2pt}`

I hope this helps!

Good luck!

Let me know if you have any questions.

Answer 2

38

Explanation:

This expression can be written as the function f(g):

`f(g)=5g-7`

If you want to evaluate this function at g = 9, just substitute 9 in for g:

`f(9)=5(9)-7\\f(9)=45-7\\f(9)=38`
