It is known that the solution set of the inequality kx-2 ＞ 0 (K ≠ 0) about X is x ＜ - 3, then the intersection of the line y = - KX + 2 and the X axis is X______ ．
The solution set of inequality kx-2 > 0 (K ≠ 0) is: X ＜ - 3, ｜ 2K = - 3, the solution of the inequality kx-2 > 0 (K ≠ 0) is: k = - 23, ｜ the analytic formula of the line y = - KX + 2 is: y = 23x + 2, in this formula, let y = 0, the solution is: x = - 3, so the intersection of the line y = - KX + 2 and the X axis is (- 3, 0). So the answer to this question is: (- 3, 0)
As shown in the figure, the two intersections of the line y = KX + B and the coordinate axis are a (2,0) and B (0, - 3), respectively. Then the solution set of the inequality KX + B + 3 ≥ 0 is ()
A. x≥0B. x≤0C. x≥2D. x≤2
The intersection of the line y = KX + B and the Y axis is B (0, - 3), that is, when x = 0, y = - 3, because the value of function y increases with the increase of X, when x ≥ 0, the value of function KX + B ≥ - 3, and the solution set of inequality KX + B + 3 ≥ 0 is x ≥ 0
If the intersection coordinates of the line y = KX + B and the coordinate axis are a (- 3,0) and B (0,2), then the inequality KX + B about X is less than or equal to the solution set of 0
If the intersection coordinates of the line y = KX + B and the coordinate axis are a (- 3,0) and B (0,2),
Then the solution set of inequality KX + b less than or equal to 0 about X is: X ≤ - 3
