Find the discriminant of -2n²+Zn+5=8, then state
the number of solutions and type of solutions.

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

Two times a number plus three times another number equals 4. three times the first number plus four times the other number is 7. find the numbers
