Answer:
B
X= 7.5
Y= -5
Step-by-step explanation:
In systems of equations, the goal is to add both of the equations together so it cancels one of the variables and you solve for that variable. Before you add they together, you multiply one of the equations by a negative number so when you add them together one of the numbers with x or y cancel.
I will upload a picture showing my work.
Answer:
1. Sometimes
2. Sometimes
3. Always
4. Sometimes
Step-by-step explanation:
1. Quadratic function : in which maximum power of is two.
The roots of quadratic function can be either equal or different.
For example:
will have two equal roots i.e. 1 and 1.
will have two different roots i.e. 1 and 2.
So, <em>sometimes </em>is the correct answer.
2. Cubic function has atleast 1 real root.
Cubic function has maximum power of as 3.
If the coefficients are real numbers then atleast 1 real root.
If the coefficients are imaginary in nature, then this is not true.
For example:
Cubic equation does not have any real root.
Cubic equation has a real root x = -1.
So, it is sometimes true.
3. A function with degree 5 i.e. maximum power of as 5 will have 5 roots.
It is always true that a function will have number of roots equal to its degree.
4. Quadratic function can have only 1 complex solution.
Two complex solutions are also possible for a quadratic function.
For example:
will have two imaginary roots:
It is also possible to have 1 complex solution,
For example:
will have one complex root and one real root.
So, the statement is <em>sometimes </em>true.
Answer:
Step-by-step explanation:
This mixed number can be separated into 25 and . Convert the fraction to a decimal by plugging it into a calculator, then add 25.
If you meant what whole number is equivalent, that does not exist.
