Alec says the sum of two numbers can never be less than either number. Use a model to explain why Alec is incorrect.

19.side- angle- side

20. angle- side- angle

step-by-step explanation:

y/x=18

step-by-step explanation:

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 )
