Given that 3y = x + 6 and y = kx + 12 are perpendicular, find the value of k

Which equation represents a line that is parallel to the line whose equation is 3x-2y=7( show all work)

In the following diagram it is given that dec,ab || dc, ad || eb, and ad is congruent to bc. a)why isn't abc a parallelogram even though it has a pair of parallel sides and a pair of congruent sides b)explain why be must be congruent to bc. further explain what type of triangle this makes triangle abc and what it tells you about angle 1 and angle 2c) finally why must angle 3 be congruent to angle 1? further, explain why we know that angle 3 is congruent to angle 2

Which expression is equivalent to -5(3x - 6/7)
