Revolt · Accepted Answer

There is one unique real number solution at (–1, –3).

Question 8

Jordan is solving this system of equations: y = 2x2 + 3 and y – x = 6. Which statements are true about Jordan’s system? Check all that apply.

Revolt · Accepted Answer

The quadratic equation is in standard form.; Using substitution, the system of equations can be rewritten as 2x2 – x – 3 = 0.; There are two real number solutions.
