In the graph of the inequality, x-2y≥4, which is a value for x on the boundary line and the x-axis? ? : )

(4, 0)

Step-by-step explanation:

The point is on the x-axis when its y-coordinate is 0. Putting that value into the inequality and solving the "equal to" case gives ...

... x -2·0 = 4

... x = 4

Then the point of interest is (x, y) = (4, 0).

answer

d. 10

explanation

the distance from point y to wx is the height of the triangle.

using pythagoras theorem,

group similar terms to get,

this implies that,

take positive square root of both sides to get,

this implies that,
