If b^2 - 4ac = 0, then b^2 = 4ac. Therefore, ac = 4 and b = + or -2.
That means that if b can be multiple things, then there a two y = equations.
y=ax^2+2x+c
y=ax^2-2x+c
so to find the intercept equations:
0=ax^2+2x+c; 0 = x(ax+2)+c; x(ax+2) = -c
0=ax^2-2x+c; 0 = x(ax -2)+c; x(ax-2) = -c
That means x has a positive and a negative value, so there is more than 1 intercept.
False.
Answer:
3558 people
Step-by-step explanation:
Since the attendance dropped 8 percent, we know that it's currently at 92% of the original number. We can set up proportions to help us solve this
92/100=3274/x
From here, we can multiply both sides by 100
3274x100 is 327400
Then we multiply both sides by x
Now we are left with 92x=327400
Divide both sides by 92
327400/92 = 3558.7
Obviously we can't have .7 of a person so I would round it down to 3558 people

Answer: 14 2/3in
Step-by-step explanation:
If 110 students play both
The 300 that play volleyball includes them.
That’s mean that 190 (300-110) play only volleyball
Also (the same) 200 play cricket, so only cricket play 90 students (200-110)
Answer: either volleyball or cricket is
(300-110)+(200-110) = 190+ 90 = 280
Answer: 280
