The domain of this function is any x-value that doesn’t cause the denominator to equal zero and cause the function to be indeterminate.

In this case, x cannot be zero, and x cannot be the square root of 5.

Simplify the expression. Write the answer with positive exponents only. Assume the variable represents a nonzero real number.

Answer:

$\frac{1}{w^{29}}$

Step-by-step explanation:

The given expression is $\frac{w^{-7}(w^{-9})^2}{w^4}$ .

Since, $w^{-7}=\frac{1}{w^7}$

And $w^{9}=\frac{1}{w^9}$

Expression will become,

$\frac{w^{-7}(w^{-9})^2}{w^4}=\frac{\frac{1}{w^7}(\frac{1}{w^9})^2}{w^4}$

$=\frac{\frac{1}{w^7\times w^{18}}}{w^4}$

$=\frac{\frac{1}{w^{(7+18)}}}{w^4}$

$=\frac{1}{w^{25}}\times \frac{1}{w^4}$

$=\frac{1}{w^{25}\times w^4}$

$=\frac{1}{w^{29}}$

Therefore, Simplified form of the given expression will be $\frac{1}{w^{29}}$ .

The table below represents a linear function f(x) and the equation represents a function g(x):

9966 [12]

Answer:

<u>Use 2 points from he table to find the slope of f(x):</u>

(0, -1) and (1, 7)

<u>The slope is:</u>

m = (7 - (-1))/1 = 8

The y - intercept is b = -1 according to point (0, -1).

<u>The lines are:</u>

f(x) = 8x - 1
g(x) = 3x - 2

The f(x) has greater slope since 8 > 3 and greater y-intercept since -1 > - 2.

See above

Answer:

x is 100 and y is 40

Step-by-step explanation:

First make 500 into a number where it can be divisable by 3. 5x40=200

500-200=300, 300 divided by 3 equals 100

x=100

y=40
