Greetings!

Number with repeating decimals are irrational  while terminating decimals are rational. This is because any number that can be expressed as a fraction/ratio is rational. 

Examples:
8: Can be expressed a fraction/ratio
8/1; Therefore, rational.

3.1415...; Can't be expressed a fraction/ratio
Therefore, irrational.

Hope this helps.

The equation of line fis - 3y + 4x = 9 write the equation of a line that is parallel to line and passes through the point (- 12,
ollegr [7]

Answer:

y =  - 4x - 42

Step-by-step explanation:

The equation of the line that is parallel to the line we are trying to find is

- 3y + 4x = 9 \\ or \\  - 3y =  - 4x + 9 \:(standard form) \\ \\therefore \: the \: slope \: of \: the \: line \\  \: is \:  - 4

We can recall that when two lines are parallel it means that they have the same slope. Therefore the slope of the line we are trying to find is also -4. We now know that:

y = 6 \:  \:  \: x =  - 12 \:  \:  \: slope =  - 4

Therefore the equation of the line is:

y = mx + c \\  6= ( - 4)( - 12) + c \\ 6 = 48 + c \\ 6 - 48 = c \\  - 42 = c

y = mx + c \\ y =  - 4x - 42

What percent of 900 is 18
horsena [70]

Fastest method for calculating what percent of 900 is 18

Assume the unknown value is 'Y', and 18 of 900 can be written as:

Y =  

18

900

By multiplying both numerator and denominator by 100 we will get:

Y =  

18

900

x  

100

100

=  

2

100

Y = 2%

Answer: 2 percent of 900 is 18

If you want to use a calculator, simply enter 18÷900x100 and you will get your answer which is 2
