Part B:
11) A line and a parabola intersect at points A and C. Their equations are:
5x 4y + 48 = 0 and y = 0.25x² 7x + 41
12) What is the result of (6x³y³ 11x²y² + 18xy 5) ÷ (3xy 1)
13) In the Cartesian plane, function f is a straight line that passes through A(0, 9) and B( t, 90).
This line is parallel to another line whose rule is g(x) = 3x 16
14) The rule of function g is g(x) = p x² + r x 36, where p and r are not equal to zero.
15) Triangle PQR has these characteristics:
16) In quadrilateral ABCD, line segments TU and VW intersect at S.
