For this case we have the following expression:
By definition, we have the expression undefined when the denominator is 0.
So:
Adding 5 to both sides of the equation:
Thus, the expression is undefined when

Answer:
The equation is 21x+4y<3150
Step-by-step explanation:
This question can be understood by the concept of inequalities.
Let x be the number of stocks of software company and y be the number of stocks of robotics company purchased.
Money invested in 1 stock of software company = $42
Money invested in 1 stock of robotics company = $8
Total expenditure on software company stock = 42*x
Total expenditure on robotics company stock = 8*y
So the total expenditure should be less than 6300
Hence the equation is
42x+8y<6300
21x+4y<3150

Answer:
x = 8
Step-by-step explanation:
Using the sine or cosine ratio in the right triangle and the exact value
sin30° = 
, then
sin30° = 
= 
= ( cross- multiply )
x = 8
The answer is D.
The first one says you add -4 each time in the sequence.
The second says you add -2 each time in the sequence.
The third says you multiply by -2 each time in the sequence.
The fourth says you multiply by -4 each time in the sequence.
-2*-4=8
8*-4=-32
