AB = x, BC = 4x, AC = 35 Find x and BC 2) AB = 5, BC = 6x + 1, AC = 42 Find x and BC
3) AB = x + 4, BC = 8x – 4, AC = 63 Find x and AB
4) AB = 2x + 4, BC = 6x + 15, AC = 91 Find x and AB
5) AB = 3x – 1, BC = 6x + 5, AC = 3x + 22 Find x and AC
6) AB = 2x – 3, AC = 9x + 14, BC = 8x – 7 Find x and AC
7) AC = 15x , BC = 5x + 14, AB = 3x + 42 Find x and BC

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 )

it is not that hard all u have to do is plot the graph

"standard form:

3x2 + 14x − 10 = 0

solutions based on quadratic formula:

x1   = −14 − √ 142 − 4×3×(−10) /   2×3   = −14 − 2 × √ 79 /   6   ≈ −5.296

x2   = −14 + √ 142 − 4×3×(−10) /   2×3   = −14 + 2 × √ 79 /   6   ≈ 0.629
