Just use logic
How can an even numbers pair and become an odd number
Answer:
(0,1)
Step-by-step explanation:
Simplify the equation to y = 1
A horizontal line always crosses the y axis.
Answer:
a and c are alternate interior angles
If some set A has n elements, then it has 2^n subsets.
Using that, the sentence, "The total number of subsets of ‘m’ is 56 more than the total number of subsets of ‘n’." gives you the equation 2^m - 2^n = 56
Factor both sides: 2^n * (2^(m-n) - 1) = 2^3 * 7
Since 2^n is a power of 2 and (2^(m-n) - 1) is an odd integer, we must have 2^n = 2^3 2^(m-n) - 1 = 7
Solving these, you get n = 3 and m = 6.
Try this option:
the final price of the first machine after discount is:
(1-0.3)*495=346.5$;
the final price of the second machine after all the discount is:
(1-(0.2+0.2*0.1))*495=386.1$.
Short explanation: the additional 10% off is 2% of the initial price for the second machine; the final discount of the second machine is 22%.
