Determine which of the lines, if any, are parallel or perpendicular. explain.

line a: 4y-12x=20
line b: 3y=-x+2
line c: y= 3x-1

What does independent variable and dependent variable mean in math?

Which statements describe the solutions to the inequality x< -20 check all that apply. there are infinite solutions. each solution is negative. each solution is positive. the solutions are both positive and negative. the solutions contain only integer values. the solutions contain rational number values.

I’ve been trying all day to figure this puzzle out. i need the work for it aswell. it is a factoring polynomials tarsia. the image is below.
