Ineed on how to solve these problems ( do not give me the answers i just want to learn how to solve these types of problems : )) part a: find a rational number that is between 7.7 and 7.9. explain why it is rational. part b: find an irrational number that is between 7.7 and 7.9. explain why it is irrational. include the decimal approximation of the irrational number to the nearest hundredth.

For part A, all you need to do is find an number between 7.7 and 7.9 but the number must terminate, or end.

For part B you must find a number that does not end and does not repeat, but round that number to the nearest hundredth.

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
