Answer:
Inverted parabola
Two complex solution
Step-by-step explanation:
any quadratic equation can be expressed in terms of ax^2 + bx + c = 0
It has two solutions which can be found using formula 
We know that for any value inside the square root function
if it is positive its solution will be real number
for example 
we can have two real solution -3 and 3
if it is negative its solution will be complex number
for example 
we can have two complex solution
expressed in term of a + ib or a - ib
------------------------------------------------------------------------------------------
Given in the problem
we have ax^2 - bx + c
so its solution will be
Since in this expression it is given in problem statement that b^2 - 4ac < 0 which will be a negative number and for negative number, its square root is complex number.
also X has two values as given above it will have two solution
hence it will have two complex solution based on above discussion.
Also for any quadratic equation shape of its curve if plotted on coordinate plane is parabolic.
If it has complex solution then curve of such expression will not pass through X axis
Step-by-step explanation:
-2y+4>10
subtract 4 from both sides
-2y+4-4>10-4
-2y>6
divide both sides by two
-2/2y>6/2
-1y>3
if negative y is greater than three than you have to multiply both sides of the equation by -1
y>-3 if you put that back into the earlier equation it is impossible.
so we have to switch the signs to < or less than
y<-3
Hope that helps:)
Answer: Hello there!
initially Maria has 6 red marbles, 6 blue marbles, and 4 green marbles.
You know that in the first pick, Maria gets a green marble ( this means that now there are 3 green marbles left)
Now we want to know the probability that she gets a red marble on the second pick.
Now there are 6 + 6 + 3 = 15 marbles in the bag, and 6 of them are red ones. Then the probability of getting one red is the number of red ones divided by the total amount ( which is the ratio of red marbles to total marbles)
this is 6/15.
now you can see that there is no 6/15 in the options, so we need to see which one is equivalent.
if we took the option C, 2/5, and multiply both denominator and numerator by 3, we get (3*2)/(3*5) = 6/15, then 2/5 and 6/15 are equivalents.
Then the correct answer is C.
