7. Find the coordinates of the ordered pair where the minimum value occurs for the equation Q = 2.c + 7y + 11, given these constraints:
*>-2
-4x + 2y > -6
x + 2y <4
O (2,1)
0 (-2,-7)
O (2,-9)
O (-2,3)

Which shows the pre image of triangle xyz

Use the quadratic formula to solve the equation. if necessary, round to the nearest hundredth. x^2 - 20 = x a. 5, 4 b. -5, -4 c. -5, 4 d. 5, -4
