Answer:
is 3/7
Step-by-step explanation:
Answer:
7. x=19 2x=38
8.x=23 3x=69
9.x=12 (50-2)/4=12
10.x=15 (31-1)/2
11.x=16 (84-4)/5
12.x=27 (55-1)/2
Step-by-step explanation:
if 2 angles are opposite, it's the same
Answer:
v = 9
Step-by-step explanation:
50 = 6v - 4
50 + 4 = 6v
54 = 6v
6v/6 = 54/6
v = 9
First simplify the equation of parabola

in the following way:

.
You can see that if x=1 or x=2, then y=0. Two points of intersection with x-axis are (1,0) and (2,0).
