I think the point k may be the centroid of the triangle, so that point would be 2/3 of the way from the vertex to the opposite side. If the ENTIRE length of AP is 18, then point K would be at the 2/3 x 18 = 12 mark. So if you're looking to find KP, it would be (18-12) = 6.

Which represents the inverse of the function f(x) = 4x?

irga5000 [103]

Answer:

y = x/4

Step-by-step explanation:

First, replace f(x) with y, so it's easier to find the inverse:

y = 4x

To find the inverse of this function, you would replace all the y's with x's and all the x's with y's, and then solve for y. That would be:

x = 4y

y = x/4

Therefore, the inverse function of y = 4x is y = x/4.

Answer: <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>

Step-by-step explanation:

The equation $x=\sqrt{6x+7}$ can be solved by squaring both sides:

$x^2 = 6x + 7\\\\x^2 - 6x - 7 = 0\\\\(x-7)(x+1) = 0$

We can see that -1 and 7 are solutions, but make sure they are not extraneous by substituting them in the original equation:

$1 = \sqrt{-1}\\ 7 = \sqrt{49}$

The square root of 49 equals 7, but the square root of -1 is an imaginary number.

The correct choice is <em>"7 is a solution to the original equation. The value –1 is an extraneous solution."</em>
