Simply, the question is this: What is the range of y = [x + 2]? It's a step function that is to be rounded down. The correct answer was apparently all multiple of 4, but wouldn't it be all integers? Since if I input x as -2 then wouldn't y come to equal 0, given that -2 + 2 would be 0 then multiplied by 4 gives y as 0. 0 wouldn't be a multiple of 4, so can someone explain to me where I went wrong?

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

Me with geometry ! in this figure, bc is a perpendicular bisects of kj. dm is the angle bisects of bdj. what is the measure of bdm? •60° •90° •30° •45°
