Answer:
B. 3x² +2 = 0
Step-by-step explanation:
The equation of A has a couple of real roots. We're pretty sure there are complex numbers that will satisfy this equation, but we don't know how to find them. (We suspect a typo, and that the equation is supposed to be 2x² +1 = 7x, which has only real roots.)
__
The equation of B can be rewritten as ...
x² = -2/3
This will have complex roots.
__
The discriminants of both equations C and D are positive, so those have only real roots.
2x² -5x -1 ⇒ d = (-5)² -4(2)(-1) = 33
3x² -6x -1 ⇒ d = (-6)² -4(3)(-1) = 48
Answer:
Daniel is 21 years old
Step-by-step explanation:
Let
R ---> Rick's age
M ---> Mike's age
L ---> Larry's age
E ---> Ed's age
D ---> Daniel's age
we know that
The sum of their ages is 271
so
----> equation 1
Rick is 5 times the age of Mike
so
----> equation 2
Mike is half the age of Larry
so
----> equation 3
----> equation 4
----> equation 5
substitute equation 2, equation 3, equation 4 and equation 5 in equation 1
simplify
-----> equation 6
substitute equation 2 and equation 3 in equation 6
solve for M
Find the value of R (equation 2)
Find the value of D (equation 5)
therefore
Daniel is 21 years old
Answer:
$666.66
Step-by-step explanation:
4%/12=0.33333
0.33333*9= 3%
2,000/3=$666.66
2,000+666.66=$2,666.66
