The correct Answer is:
To solve the problem of finding the distance from the point of intersection of the lines \(2x - 3y + 5 = 0\) and \(3x + 4y = 0\) to the line \(5x - 2y = 0\), we will follow these steps: ### Step 1: Find the point of intersection of the lines We have two equations: 1. \(2x - 3y + 5 = 0\) 2. \(3x + 4y = 0\) To find the intersection, we can solve these equations simultaneously. From the second equation, we can express \(y\) in terms of \(x\): \[ 4y = -3x \implies y = -\frac{3}{4}x \] Now, substitute \(y\) in the first equation: \[ 2x - 3\left(-\frac{3}{4}x\right) + 5 = 0 \] \[ 2x + \frac{9}{4}x + 5 = 0 \] To eliminate the fraction, multiply through by 4: \[ 8x + 9x + 20 = 0 \implies 17x + 20 = 0 \implies x = -\frac{20}{17} \] Now substitute \(x\) back to find \(y\): \[ y = -\frac{3}{4}\left(-\frac{20}{17}\right) = \frac{60}{68} = \frac{15}{17} \] Thus, the point of intersection is: \[ \left(-\frac{20}{17}, \frac{15}{17}\right) \] ### Step 2: Find the distance from the point to the line The distance \(d\) from a point \((x_1, y_1)\) to a line \(Ax + By + C = 0\) is given by the formula: \[ d = \frac{|Ax_1 + By_1 + C|}{\sqrt{A^2 + B^2}} \] For the line \(5x - 2y = 0\), we can rewrite it as: \[ 5x - 2y + 0 = 0 \] Here, \(A = 5\), \(B = -2\), and \(C = 0\). Now substituting the point \(\left(-\frac{20}{17}, \frac{15}{17}\right)\) into the distance formula: \[ d = \frac{|5\left(-\frac{20}{17}\right) - 2\left(\frac{15}{17}\right) + 0|}{\sqrt{5^2 + (-2)^2}} \] Calculating the numerator: \[ = \frac{|- \frac{100}{17} - \frac{30}{17}|}{\sqrt{25 + 4}} = \frac{|- \frac{130}{17}|}{\sqrt{29}} = \frac{\frac{130}{17}}{\sqrt{29}} \] Thus, the distance is: \[ d = \frac{130}{17\sqrt{29}} \] ### Final Answer The distance of the point of intersection from the line \(5x - 2y = 0\) is: \[ \frac{130}{17\sqrt{29}} \]

To solve the problem of finding the distance from the point of intersection of the lines \(2x - 3y + 5 = 0\) and \(3x + 4y = 0\) to the line \(5x - 2y = 0\), we will follow these steps: ### Step 1: Find the point of intersection of the lines We have two equations: 1. \(2x - 3y + 5 = 0\) 2. \(3x + 4y = 0\) ...
