Given:
The expression is
To find:
The equivalent expression.
Solution:
We have,
It can be written as
So, option C is correct.
So, option A is correct.
The given expression can be written as
So, option D is incorrect.
So, option B is incorrect.
Therefore, the correct options are A and C.
Answer:
exactly one
Step-by-step explanation:
The system of linear equations have:
one solution, infinitely many solutions or no solution.
One solution if the lines intersect.
Infinitely many solutions if the lines are the same (overlap)
There is no solution if the lines are parallel (they do not have a common point).
In the graph, two lines intersect. Therefore, the system of equations has one solution (0, 3).
According to a center for disease control. We can’t compute the probability.
<u>SOLUTION:
</u>
Given that, According to a center for disease control,
The probability that a randomly selected person has hearing problems is 0.157.
The probability that a randomly selected person has vision problems is 0.096.
We have to find whether we can compute the probability of randomly selecting a person who has hearing problems or vision problems by adding these probabilities or not?
The answer is no, because hearing and vision problems are not mutually exclusive.
So, some people have both hearing and vision problems.
These people would be included twice in the probability.
Hence, we can’t compute the probability.
Answer: C option
Step-by-step explanation:
Since the drawing is 5x more than real object then we have to divide the numbers
a= 35/5 = 7
b= 30/5 = 6
c= 15/3 = 3
<span>y=-x+5/2..................(2)
the slopes of equations (10) & (2) are same and the intercepts are different
so the lines are parallel.
it has no solution </span>
