Answer:
$2
Step-by-step explanation:
Intial fee is x. Number of stops is y. You can set up these equations.
- x+4y=8
- x+8y=14
- x+12y=20
You can subtract one from the other:
x+8y=14
- x+4y=8
–––––––
4y=6
We now know that 4y=6. The first equation had 4y, so we can put 6 instead of 4y.
- x+6=8
- Subract 6, x=2
Part A:
For this case we have the following equation:
10x2 - 3x - 1 = 0
The radicand of the equation is:
root (b ^ 2 - 4 * a * c)
Substituting values:
root ((- 3) ^ 2 - 4 * (10) * (- 1))
root (9 + 40)
root (49)
49> 0
Therefore, the function has two real roots.
Part B:
For this case we have the following equation:
16x2 - 2x - 5 = 0
Factoring we have:
(2x + 1) * (8x-5) = 0
The solutions are:
x = -1/2
x = 5/8
The method of factoring is usually faster when solving quadratic equations.
