riadik2000 [5.3K]

Answer:

5, 8, and 9

Step-by-step explanation:

If the function is to be factorable, then k must be values which have factors that add to 6.

6 can be added as 1+5, 2+4, and 3+3. These pairs of factors multiply to 5, 8, and 9.

kyle is packing his things to move. He wonders if his 41 inch golf club will fit in a box that is 9 inches by 12 inches by 35 in

jonny [76]

Using the pythagorean theorem, a^2+b^2=c^2
a=35
b=12
c=?

1225+144=1369
square root of 1369 is 37

Therefore his golf club will fit because it is 35 inches long and the box is 37 inches long at an angle.

F(x) = 2x+1/×-1 find the inverse function

denis23 [38]

To factor this, start by replacing x with y and then solve for y
$f(x) = \frac{2x+1}{x - 1}$
$x = \frac{2y+1}{y - 1}$
$(y-1)x = \frac{2y+1}{y - 1} * (y-1)$
$(y-1)x = 2y+1$
$xy -x = 2y+1$
$xy - 2y -x +x = 2y - 2y +x+1$
$xy - 2y = x+1$
Factor out y on the left side.
$\frac{xy - 2y}{y} = x+1$
$y(x - 2) = x+1$
$\frac{y(x - 2)}{(x-2)} = \frac{x+1}{x-2}$
$y = \frac{x+1}{x-2}$
$f(x)^{-1} = \frac{x+1}{x-2}$
