|-5x+10| is just 5x + 10 > 10

so 5x + 10 > 10
         -10     -10


5x > 0
/5      /5

x > 0 is the answer to this Inequality

hope this helps ;-)

To solve an equation of the form |X| > k, where X is an expression in x and k is a number, solve the two compound inequality,

X < -k or X > k

Now we can do this problem.

<span>|-5x + 10| > 10

-5x + 10 < - 10 or -5x + 10 > 10

-5x < -20 or -5x > 0

x > 4 or x < 0

The solution is x < 0 or x > 4.

The graph is an number line with an open circle at 0 and shaded to the left of zero, and an open circle at 4 and shaded to the right of 4.

Write a rule for the following functions. I need help fast!
marishachu [46]

Answer:

  20.  y = 3·3^x

  21.  y = (1/3)^x

Step-by-step explanation:

These exponential functions can be written in the form ...

  y = a·b^x

where a is the value of y when x=0, and b is the common ratio between terms that have x different by 1.

__

20. The ratio is 9/3 = 3; the multiplier is 3 (the value of y when x=0), so the function is ...

  y = 3·3^x

__

21. The ratio is (1/3)/1 = 1/3; the multiplier is 1, so the function is ...

  y = (1/3)^x

_____

<em>Alternate solution</em>

Each of these can be written in a more compact form:

  20: y = 3^(x+1)

  21: y = 3^(-x)

50 points!
Thepotemich [5.8K]

Answer:

D

Step-by-step explanation:

An excluded value is any value of x that makes the denominator of the rational expression zero as this would make the expression undefined.

Consider expression D

\frac{6}{x+5}

This will be undefined when

x + 5 = 0 ⇒ x = - 5 ← excluded value → D
