Question 4

Revolt · Accepted Answer

0; 1; 2; 3; 4

Question 5

Use substitution to solve.2x² = 5 + y4y = -20 + 8x²Solve the first equation for y and substitute it into the second equation. The resulting equation is .

Revolt · Accepted Answer

8x² - 20 = -20 + 8x²

Question 6

The solution of 2x2 + x = 3 is shown below.2x2 + x – 3 = 0(2x + 3)(x – 1) = 0x = –1.5 or x = 1Based on this work, the solution of the system of equations is .
