When m is the value, the focus of the line y = 5x + m on the line y = 3x-4 is on the x-axis?

When m is the value, the focus of the line y = 5x + m on the line y = 3x-4 is on the x-axis?

Focus on x-axis, set as (x, 0), 3x-4 = 0, 5x + M = 0, x = 4 / 3, M = - 20 / 3

The area of △ ABC is ()
A. 2B. 4C. 6D. 8

The graph of the linear function y = 3x + P and y = x + Q passes through the point a (- 2, 0). Substituting (- 2, 0) into the analytic formula, we get - 6 + P = 0, - 2 + q = 0, and the solution is p = 6, q = 2. Then the analytic formula of the function is y = 3x + 6, y = x + 2. The intersection of the two functions and the Y axis is B (0, 6), C (0, 2). So CB = 4, so the area of △ ABC is 12 × 2 × 4 = 4

Given the quadratic equation 3x-5y = 10, please write its three integer solutions

x=5 Y=1 X=10 y=4.x=15.y=7.

Function y = Y1 + Y2, and Y1 = 2x + m, y2 = 1 / (m-1) * x + 3, the intersection of two images is 4, find the functional relationship between Y and X
The function y = Y1 + Y2, and Y 1 = 2x + m, y 2 = 1 / (m-1) * x + 3, the intersection of two images is 4, find the functional relationship between Y and X
It's urgent

Y1 = 2x + m, y2 = 1 / (m-1) * x + 3, the intersection of the two images is 4
Substitute y2 = 1 / (m-1) * x + 3 to get x = 1 / (M + 1)
Substitute x = 1 / (M + 1) into Y1 = 2x + m to get
M = 2 or M = 3
So the functional relationship between Y and X is y = 2x + 1 / x + 5 or y = 2x + 1 / 2x + 6
