1 answer:
slamgirl [31]3 years ago

Answer:

Gah! Inverses!

Step-by-step explanation:

This is a pretty simple concept, just switch the x and f(x) values!

If you don't understand, look at how I solve it!

f(x)=\frac{1}{3} -\frac{1}{21} x

Switching the positions of the x and f(x) values...

x=\frac{1}{3} -\frac{1}{21} f(x)^{-1}\\

Note: That f(x)^-1 is the proper notation for inverse functions.

x-\frac{1}{3} =-\frac{1}{21} f(x)^{-1} \\f(x)^{-1}=-21x+7

There you go!

Hope this helps, and don't procrastinate!

Can someone help me please I need the mode, median, range and the mean.?
Neko [114]

Answer:

First the mode.  Since 5 popped up the most, 5 is the mode.

Next is the median.  I crossed 1 dot from each side until it shows the last dot, and 5 was the last one.

After that the range.  9-2=7

Finally the worst, the mean... 2+2+3+3+3+4+5+5+5+5+5+6+6+6+8+9+9+9+9

=104/19=5.47

SO, Mode=5 Median=5 Range=7, and the mean is 5.47 (rounded nearest hundred)

Solve each equation by graphing the related function. If the equation has no real-number solution,write no solution .
3241004551 [841]
See each answer below.

1) If we subtract 7 from both sides and try to take the square root, we are taking the square root of -7. Therefore, there are no solutions.

2) Dividing by 3 and taking the square root gives an answer of 0.

3) Add 4, multiply by 4 and finally take the square root of each side.You will get positive or negative four.

4)  Divide by 4 and then take the square root. You have positive or negative 5/2.

15. True or False: Is x = 4 a solution to X + 51 = -9<br> True<br> False
Ivenika [448]

Answer:

False, also the typed version of this problem does not actually use the expression in the accompanying screenshot. That clearly reads as x + 5

Step-by-step explanation:

The problem, assuming x = 4 can be read as 4 + 5. Simple math dictates this would equal nine and as there is no negative to either number nor a negative outside of the lines surrounding the problem itself the solution is simple and leads to a false answer.
