Answer: a = 5.5
Step-by-step explanation:
95 = -20a - 25 + 10
95 = -20a - 15
-20a = 110
a = 5.5
Answer:
Step-by-step explanation:
56y^2/9-30y+25
Answer:
6
Step-by-step explanation:
The rational root theorem states that the roots must be factors of p/q
where p is the constant and q is the coefficient of the highest order term
p = 8 which has factors ±1, ±2,±4,±8
q = 1 which has factors ±1
The possible roots are ±1, ±2,±4,±8
--------------------
±1
which simplifies to
±1, ±2,±4,±8
6 is not a possible root
The value of x is determined by an equation where both sides are equal.
Step one, factor the denominators:
5x/(x-1)(x-6)-3(x+2)/(x+2)(x-6)
step two: make the denominators the same, the first fraction multiple (x+2), both top and bottom, the second one multiply (x-1), both top and bottom
simplify, I eventually get the answer (2x+3)/(x^2-7x+6)
