Answers:
1A. You see, every amount of T shirts costs 5.5 times more than it's amount. So if "n" is the number of shirts and "C" is what it costs, then the equation must be C=5.5n.
1B. Idon't know how to graph it here sorry.
1C. You have to look back to the equation. It has our coefficient (5.5n) on one side and C on the other,so the answer is just 5.5n. Now the questions says 120 shirts so (120)5.5 equals 660.
1D. I just did
<span>(3x−2)(2x+3)=0
</span><span>(3x−2)=0; x = 2/3
</span><span>(2x+3)=0; x = -3/2
answer
x = -3/2 and x = 2/3</span>
It would be 8 because 3 less than 8.
Hope this helps! :D
Try using the back of the book.
Explanation:
The common difference of this arithmetic sequence is 5. Adding 5 to an even number gives an odd number, and vice versa. Hence the "parity" of the terms in the sequence must alternate between odd and even.
