6a. 1 - 2sin(x)² - 2cos(x)² = 1 - 2(sin(x)² +cos(x)²) = 1 - 2·1 = -1
6c. tan(x) + sin(x)/cos(x) = tan(x) + tan(x) = 2tan(x)
6e. 3sin(x) + tan(x)cos(x) = 3sin(x) + (sin(x)/cos(x))cos(x) = 3sin(x) +sin(x) = 4sin(x)
6g. 1 - cos(x)²tan(x)² = 1 - cos(x)²·(sin(x)²)/cos(x)²) = 1 -sin(x)² = cos(x)²
Answer:
System A the answer is: One solution
System B the answer is: Many infinite solution
System C the answer is: No solution
Step-by-step explanation:
Hope this helps you :)
Your answer would be if i'm correct
M^2-8m-7
If not that one
M^2+8m+7
The answer is $57.50.
Explanation:
To find the discounted price of an item, you multiply the original sell price of the item by a decimal version of the percentage. So in this case you would multiply .25 by 230 to get 57.5 or $57.50.
I hope I helped and good luck!
