Answer:

Step-by-step explanation:
The given function is

To find the inverse, we interchange x and y to get:

We now solve for y by taking antilogarithm.

Therefore the inverse of the given exponential equation is the logarithm function

Let's find X. Since both equations are equal to y, they are equal to themselves.
-3x-3=-3; we just need to solve from here. -3x-3=-3; let's add 3 to both sides. -3x=0; this means that 0 is X.
Let's use a graph to check.
So, y is -3.
So, (0, -3) is when the two lines intersect and it's our solution.

Answer:
see explanation
Step-by-step explanation:
The statements tells us that w is inversely proportional to v and the equation relating them is
v =
← k is the constant of proportion
To find k use the condition v = 9, w = 5, that is
9 =
( multiply both sides by 5 )
45 = k
v =
← equation of proportion
When w = 4 , then
v =
= 11.25
