Substituting y=6x+2 into equation 3y - 18x =12 looks like:
3(6x + 2) - 18x = 12
18x + 6 - 18x = 12 distributive property left side
6 = 12 simplifying the left side
We now see a contradiction: 6 does not equal 12 What this tells us is that there is no solutions to this equation. So choice 'C' ...
the greatest common factor is 1
<u>Answer</u>
Irrational number
<u>Explanation</u>
√42 = 6.480740698.......
Rational numbers are numbers that ca be written as a fraction. that is in form of a/b.
√42 can not be written in the form of a/b, neither is it a whole number. So √42 is not a rational number.
The answer is the last one. irrational number.
