What is the inverse of the function

sleet_krkn [62]

Answer:

$x^2-10x+31$

Step-by-step explanation:

$y=\sqrt{x-6}+5$

$x=\sqrt{y-6}+5$

$\sqrt{y-6}+5=x$

$\sqrt{y-6}+5-5=x-5$

$\sqrt{y-6}=x-5$

$\left(\sqrt{y-6}\right)^2=\left(x-5\right)^2$

$\left(\sqrt{y-6}\right)^2$

$=\left(\left(y-6\right)^{\frac{1}{2}}\right)^2$

$=y-6$

$\left(x-5\right)^2$

$=x^2-10x+25$

$y-6=x^2-10x+25$

$y-6+6=x^2-10x+25+6$

$y=x^2-10x+31$

PLS HELP! DUE IN 30 MINS!!!!!

erik [133]

Answer:

Inequality: 22 + 5x ≥ 59

Minimum amount: 7.4

Realistic number: 8

Represented on a graph: I think it would look like a vertical line starting at the x value of 8, and continue right forever

Step-by-step explanation:

22 because that's how much she has already, 5x will represent her earnings relative to the number of driveways she pressure washes, and greater than or equal to 59 because she needs $59 or more to buy the video game.

22 + 5x ≥ 59 (subtract 22 from each side)

5x ≥ 37 (divide each side by 5)

x ≥ 7.4

Show all your work to receive credit!<br><br> What is m∠KNLm∠KNL?

irina1246 [14]

With intersecting lines, the angles opposite the intersection (across the "X") are called vertical angles, and they are identical. Therefore JNK = MNL and KNL = JNM.
So set KNL = JNM:
3(x+14) = 5x+2
3x+42 = 5x+2
3x+42 -42 = 5x+2 -42
3x = 5x -40
3x -5x = 5x-5x -40
-2x = -40
-2x/-2 = -40/-2
x = 20
Now plug that into x for KNL:
KNL = 3(x+14) = 3(20+14) = 3(34) = 102°
