Which graph shows the solution to this system of inequalities? y ≤ 3x + 2 y > -2 - x

Graph A

Step-by-step explanation:

one with positive slope has to be bold and the line with negative slope has to be dotted.

Region should be below the bold and above the dotted line

9514 1404 393

  60 ft

Step-by-step explanation:

The formula for the area of a trapezoid is ...

  A = 1/2(b1 +b2)h

Fill in the given information and solve for h.

  8400 ft² = (1/2)(280 ft)h

  h = 8400 ft²/(140 ft) = 60 ft

The altitude of the trapezoid is 60 feet.
