9 × 9 would be the answer or just 9. Since 9 × 9 = 81. So, I believe you could put 9 if there is only one x spot but if there is 2 you can put 9 × 9. Hope this helps! c:

Evaluate 4<br> M-n if m= -7 and n = 2.

gregori [183]

Answer:

-30

Step-by-step explanation:

I'm assuming the equation is $4m-n$ . If it is not please tell me.

If we know the values of m and n, we can just substitute inside the expression.

$4(-7) - 2\\\\-28 - 2\\\\-30$

Hope this helped!

I need help with an Algebra question. The question is in the picture. Thank you <3

The domain is the set of allowed inputs, in this case t values. The smallest t value allowed is t = 0. The largest is t = 165. So that's why the domain is $0 \le t \le 165$

-------------------------------

The range is $0 \le H \le 40000$ since H = 0 is the smallest output of the function and H = 40,000 is the largest output. Like the domain, the range is the set of possible outputs of a function.
