Answer:
The x -coordinate(s) of the point(s) of intersection of these two polynomials are
The sum of these x -coordinates is
Step-by-step explanation:
The intersections of the two polynomials, p(x) and q(x), are the roots of the equation p(x) = q(x).
Thus, and we solve for x
Using Zero Factor Theorem: = 0 if and only if = 0 or = 0
The solutions are:
The sum of these x -coordinates is
We can check our work with the graph of the two polynomials.
Answer:
a. angles A and C
b. angles B and D
Step-by-step explanation:
When two lines are parallel, it implies the value of the angle between them is . Thus the lines can not meet when extended continuously.
Alternate angles are two equal angles that lie on opposite sides of the transversal line. Alternate Interior Angles are a pair of equal angles on the inner side of two parallel lines.
Since lines DE and AB are parallel with alternate interior angles at B and D, then angles A and C with angles B and D are alternate interior angles.
i.e < A = < C (alternate interior angle property)
<B = < D (alternate interior angle property)
