Answer:

A parallelogram with diagonals that are congruent and opposite sides that are congruent.

A square is defined as having all sides equal, and its interior angles all right angles (90°). From this it follows that the opposite sides are also parallel.

The price of a particular stock is represented by the linear equation y=-0.91x+103.47
Mama L [17]

To find the price of the stock after 12 weeks, you would have to plug in 12 to x

That would make your equation: y = -0.91(12) + 103.47

Then, you solve:

-0.91(12) would be -10.12

Your equation will now look like this:

y = - 10.12 + 103.47

Then you add -10.12 to 103.47

-10.12 + 103.47 = 92.55

y = 92.55

After 12 weeks, the price of the stocks would be $92.55
