If the diagonals of a quadrilateral are congruent, is the quadrilateral always a rectangle?

Step-by-step explanation:

The answer is yes, the diagonals of a quadrilateral are always a rectangle if they are congruent. This is actually one of the definitions of a rectangle! I hope this helps!

it would be:

c.parallelogram.

so firstly, we need to isolate the y variables to be able to solve these inequalities. firstly, add 0.5x on both sides of the first inequality and subtract 1.5x on both sides of the second inequality:

now since the slope is positive for the first inequality, this means that the line going upwards belongs to the first inequality, and the line going downwards belongs to the second inequality.

next, since y ≥ in the first inequality, this means that the shaded region will be above the first inequality's line, thus shading regions a and b.

next, since y ≤ in the second inequality, this means that the shaded region is going to be below this line, thus shading regions a and c.

since both lines shade region a, this means that region a is the solution.
