Answer:
D
Step-by-step explanation:
I'm not really 100% sure this is a weird question but I would assume D because if something is not proportional or doesn't conform to an equation, it has no slope
Answer:
![a=-1,\ a=-5](https://tex.z-dn.net/?f=a%3D-1%2C%5C%20a%3D-5)
![x=-2+i,\ -2-i](https://tex.z-dn.net/?f=x%3D-2%2Bi%2C%5C%20-2-i)
Step-by-step explanation:
<u>Equations</u>
We have two cases where some variable is required to be found such that some condition is met. The first case is about finding the value of a that complies:
![a^2+7a+6=a+1](https://tex.z-dn.net/?f=a%5E2%2B7a%2B6%3Da%2B1)
Rearranging
![a^2+6a+5=0](https://tex.z-dn.net/?f=a%5E2%2B6a%2B5%3D0)
Factoring:
![(a+1)(a+5)=0](https://tex.z-dn.net/?f=%28a%2B1%29%28a%2B5%29%3D0)
There are two solutions:
![a=-1,\ a=-5](https://tex.z-dn.net/?f=a%3D-1%2C%5C%20a%3D-5)
The second case requires us to find the value of x such that
![3x^2-x+1 =2x^2+5x-4](https://tex.z-dn.net/?f=3x%5E2-x%2B1%20%3D2x%5E2%2B5x-4)
Rearranging
![x^2+4x+5=0](https://tex.z-dn.net/?f=x%5E2%2B4x%2B5%3D0)
This second-degree equation has no real roots. We'll offer the imaginary (complex) solutions:
![x=-2+i,\ -2-i](https://tex.z-dn.net/?f=x%3D-2%2Bi%2C%5C%20-2-i)
Answer: 0.2
Step-by-step explanation:
The number of marbles in the bag illustrates probability
The conclusion about the number of marbles in the bag is that the bag can only contain one type of marble
<h3>The number of marbles in the bag?</h3>
The probabilities are given as:
P(Red) = 1
P(Green) = 1
For a distribution, the sum of all probabilities must equal to 1.
This means that:
P(Red) + P(Green) = 1
So, we have:
1 + 1 = 1
This gives
2 = 1
The above equation is false because 2 does not equal to 1.
So, the conclusion about the number of marbles in the bag is that the bag can only contain one type of marble i.e. either red marbles are in the bag or blue marbles are in the bag
