Find the equation of the axis of symmetry and the coordinates of the vertex of the graph for each function" y=x^2+5x-12 y=1/4x^2+8x

1760 kilometers

step-by-step explanation:

multiply the amount of time the plane took to travel by it's speed

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 )
