I need help with this math problems
Solving Linear-Quadratic Systems

1. y = x^2 + 4x + 5

y = x – 5

2. y = x^2 - 2x – 7

y = x – 3

3. y = x^2 - 4x + 5

y = 3x – 1

4. y = x^2 – 16

y = x – 14

5. y = x^2 - 4x – 5

y = 5x + 5

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

Based on the diagram, match the trigonometric ratios with the corresponding ratios of the sides of the triangle. tiles : cosb sinb tanb sincposs matches: c/b b/a b/c c/a

The pyramid below was dissected by a horizontal plane which shape describes the pyramid horizontal cross section
