Which of the following is the inverse of y=3^x?
mojhsa [17]

For this case, we must find the inverse of the following function:

y = 3 ^ x

We follow the steps below:

We exchange the variables:

x = 3 ^ y

We put the variable y on the left side of the equation:

3 ^ y = x

We apply logarithm properties:

y = log_ {3} (x)

So:

f ^ {- 1} = log_ {3} (x)

Answer:

f ^ {- 1} = log_ {3} (x)

Option B

FOR 15 POINTS I WILL GIVE BRAINLEST IF YOU ARE CORRECT! What is the solution to the system that is created by the equation y = 2
goblinko [34]

The solution point is (4,2).

Step-by-step explanation:

Equation of straight line passing through the points (0,0) and (4,2) is given by

⇒ 2y = x ............ (1)

And the other straight line is y = - x + 6 .............. (2)

Now, solving equations (1) and (2) we get, y = - 2y + 6

⇒ 3y = 6

⇒ y = 2

And from equation (1) we get, x = 2y = 4

Therefore, the solution point is (4,2). (Answer)

A video company randomly selected 100 of its subscribers and asked them how many hours of shows they watch per week. Of those su
Xelga [282]

Hello there!

35/100 watch more then 10 hours a week

3000 is 30 times greater than 100 so we can simply multiply 35/100 by 30.

35/100 x 30 = 1050/3000

Therefore, if the company had 3,000 subscribers, 1,050 subscribers would be watching more than 10 hours a week.
