Find the area of the irregular figure 3 in 3 in 4 in 4 in 6 in 8 in

Solve: 3x+y=6 4x-2y=18 show all work !

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

The quadratic function h(t)=-16.1t^2+150 choose the graph representation
