2. The average distance between planet Neptune and the Sun is about 4 × 109 kilometers. What
is 4 × 109 written in standard notation?
A. 0.0000000004
B. 0.000000004
C. 400,000,000
D. 4,000,000,000

r and t.

both are 64 degrees.

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 )
