Consider the sequence 3, 7, 11, 15, ... Enter numbers in the boxes to represent the third term as an ordered pair

How do i do this? i don’t understand

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 trigonometric ratios sine and secant are reciprocals of each other
