For which rational expression is 8 an excluded value ? check all that apply

denis23 [38]

Answer:

The correct answer options are C. $\frac{x^2+5}{x-8}$ and D. $\frac{x^2-x-56}{x^2-64}$ .

Step-by-step explanation:

The values which make the denominator equal to zero are called the excluded values.

Here, we can substitute 8 for x and check if it makes the denominator 0.

$\frac{x-8}{x+8} = \frac{8-8}{8+8} =\frac{0}{16} =0$

$\frac{x-2}{x^2-4} = \frac{8-2}{8^2-4} =\frac{6}{60} =\frac{1}{10}$

$\frac{x^2+5}{x-8} = \frac{8^2+5}{8-8} =\frac{69}{0}$

$\frac{x^2-x-56}{x^2-64} = \frac{8^2-8-56}{8^2-64} = \frac{0}{0} =0$

$\frac{8x^2-2}{x^2-16} = \frac{8(8)^2-2}{8^2-16} =\frac{510}{48}$

Answer:

16. 3/8
17. 1/8
18. 5/18
19. 0
20. 1

Step-by-step explanation:

As per the spinner we have:

Green = 1/2 - 1/16 = 7/16
Red = 1/4
Purple = 1/8
Orange, blue, yellow = 1/16

16. P(red, yellow, blue) = ?

P = 1/4 + 1/16 + 1/16 = 3/8

17. P(orange, yellow) = ?

P = 1/16 + 1/16 = 1/8

18. P(green, blue, purple) = ?

P = 7/16 + 1/16 + 1/8 = 10/16 = 5/8

19. P(pink) = ?

P = 0 as no pink section

20. P(red, orange, yellow, green, blue, purple) = ?

P = 1 as all possible colors selected
