Answer: F. Initially the pipe leaks at 17 gallons per minute.
Step-by-step explanation:
Given the equation below:
R = 17 + 4t
Where R is the rate of leakage in gallons per minute,
And t is the age of pipe in years.
The rate of leakage at time t = 0 ( initial rate of leakage )
R(0)= 17 + 4(0)
R(0)= 17 gallons per minute.
Therefore the initial rate of leakage is 17gallons per minute
If you meant...
(x^2+2x-5)/(6x-2)-(3x-2)/2
You need a common denominator of 2(6x-2)=(12x-4)
(2x^2+4x-10-(3x-2)(6x-2))/(12x-4)
(2x^2+4x-10-18x+6x+12x-4)/(12x-4)
(2x^2-8x-14)/(12x-4)
(x^2-4x-7)/(6x-2)

Answer:
Two real roots
Step-by-step explanation:
The portion of the quadratic formula that determines the number of roots is
b² - 4ac
If it's positve there are two real roots
If it's zero there is one real root
If it's negative there are no real roots
------------------------------
b² - 4ac = 7² - 4(3)(-8)
b² - 4ac = 49 + 96
b² - 4ac = 145
Two real roots since 145 is positive
