How do you do 20x-10y=50 10x-15y=-5 in system of equations

Given a(-12,5) and b(12,29) find the point that divides the line segment ab three-eighths of the way from a to b

If the table of the function contains exactly two potential turning points, one with an input value of –1, which statement best describes all possible values of m? m ≥ –12 –12 < m < 4 m ≤ 4 m ≥ 4 or m ≤ –12

Two line segments are shown in the figure below. suppose that the length of the line along the x-axis is 6, and the length of the hypotenuse of the triangle is 10. what is the equation of the hypotenuse line (shown in red, below)?
