Question

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

Answer 1

Answer:

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

Step-by-step 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.

$\sf = 5 \times 9 - 7$

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

Answer:

38

Step-by-step 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:

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