-2m + 15 = 45 (original problem)
-2m = 30          (remove 15 from both sides)
-2m/-2 = 30/-2 (divide by -2)
m = -15

STatiana [176]

Answer:

To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and f^{-1}(x)= \frac{ln\ x+4}{2}

Step-by-step explanation:

Data provided in the question

f(x) = e^2x - 4

Now

to find the inverse let

So,

y = e^2x - 4

Now

Replace x and y

Therefore

x = e^2y - 4

Now compute the value of y

So,

x + 4 = e^2y

Now take ln on both sides:

The equation is

ln(x+4) = ln(e^2y)

ln(x+4) = 2y

y = ln(x+4) ÷ 2

f^{-1}(x)= \frac{ln\ x+4}{2}

Therefore,  To determine the inverse of the given function, change f(x) to y, switch x and y and solve for y and f^{-1}(x)= \frac{ln\ x+4}{2}

How do you work out the value of x?
denis23 [38]

Answer: 45

Step-by-step explanation:

The total degrees in a circle is 360.

The perpendicular angle that you see is 90 degrees, added to angles of x and 3x, you get the total degrees.

so 90 + x + 3x = 90 + 4x = total

90 + 4x = 360

4x = 180

x = 45 degrees
