SOLUTION: Given that the graph of the equation y = 2x+7/square root of 9-4x�,intersects the x axis once, how do I calculate the coordinates of this point of intersection

Question 288598: Given that the graph of the equation y = 2x+7/square root of 9-4x�,intersects the x axis once, how do I calculate the coordinates of this point of intersection

Intersecting the x axis means y is zero
set your equation to y=0 and solve for x.
Is this the problem?

x=-7/2

2x+7=0
2x=-7
x=-7/2
