Are these a rational function? 1.) y = 3/x
2.) q(x) = (5x-30) / (10x +20)
3.)(2x-5)/ x-x
4.)p(x) = 5x / (x^3 -27)
5.)y = √(2x) / x+1
6.) y = 3/(5-x^2)
7.) f(x) = (x+5)/x
8.) g(x) = x^0 / (x

Please reply asap

the answer is 96 degrees

step-by-step explanation:

you have to realize that a line equals 180 degrees

idk

step-by-step explanation:

use that smart brain

3-4

step-by-step explanation:

the answer is 3-4 because both 45 and 60 has a multiple of 15.

45/3=15

60/4=15

therefore the odds against selecting a red is 4-3

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
