Answer: The answer is (C).
Step-by-step explanation: The given statement is - "Two matrices are row equivalent if they have the same number of rows". We are to explain whether the statement is true or false.
What are row equivalent matrices? The answer to this question is -
Two matrices are said to be row equivalent if one of the matrices can be obtained from the other by applying a number of elementary row operations. Or, we can say two matrices of same order are row equivalent if they have same row space.
Thus, the correct option is (C).
False. If you want to make 1.65 × 10to the power of 2 you would move it right two spots. Now if it was 1.65×10-2 then you would move it to the left.
15.66 is what I got in my calculator if you turn %65 into .65

Answer: 17.25 dollars</h3>
=======================================================
Explanation:
15% of 15 = 0.15*15 = 2.25
The cost has increased by $2.25 which means the cost per kilogram is now 15+2.25 = 17.25 dollars
------------
As a slight shortcut, we can multiply the old cost (15) by the multiplier 1.15 to get the same result:
1.15*15 = 17.25
This method allows us to chain together many percentage increases, and it also allows us to include percentage decreases as well. Note how 1.15 is basically the result of 100% + 15% = 1.00+0.15 = 1.15
Answer:
there are no real solutions
Step-by-step explanation:
there is a rule that says
so we have
and we have the definition
so we have
and using the quadratic formula we get that
there are no real solutions
