x = 20 is the answer.
<u>Step-by-step explanation:</u>
When a parallel lines cut by a transversal, then the alternate exterior angles are congruent.
So the given 2 angles add up to 180 degrees.
5x+ 9 + 3x+ 11 = 180
8x + 20 = 180
8x = 180 - 20 = 160
x = 160/8 = 20
B. To see if it’s a function, it has to pass the vertical line test. That means draw a vertical line (going up and down) through any point on the graph and it can only go through one point. If it goes through more than 1, it’s not a function. Like in graph A, if you draw a vertical line at x=-2, it will go through two points, same at x=2. For graph b, no matter where you move a vertical line, it only passes through one point at a time, so it passes the vertical line test.
Answer:
b = 6 / 1/4

C)
Answer:
49
Step-by-step explanation:
25b² + 70b + ....
( 5b + 7)² = 5×5b² + 2×5×7b + 7×7 = 25b² + 70b + 49
