? ÷ 4 = 9

please help me

Your answer would be 36

Step-by-step explanation:

You can figure this out by multiplying B by C to get A or

4 x 9 = 36

Then you can check by going

36 ÷ 4 = 9

9 = 9

This is the right answer

36

Step-by-step explanation:

You are solving for ?. Let ? become the variable (x).

x ÷ 4 = 9

Note the equal sign, what you do to one side, you do to the other. Isolate the variable, x. To do so, multiply 4 to both sides:

x ÷ 4 (* 4) = 9 (* 4)

x = 9 * 4

x = 36

36 is your answer.

For f(-11) replace x with -11 and solve:

f(-11) = 100 / -10 +e^-0.1(-11)

f(-11) = 100 / -10 +e^1.1

f(-11) = -14.3
