Answer:
-7 degrees
Step-by-step explanation:
Make sure to double check, but I think this is the answer.
cos 2 x = cos² x - sin² x = 1 - sin² x - sin² x = 1 - 2 sin² x.
Answer: A ) 1 - sin² x and D ) cos² x - sin² x
Thank you.
Answer: sorry about that Evaluate for y=8
9x+(4)(8)
9x+(4)(8)
=9x+32
Hope this help :D
The answer is the third option, which is:
<span> y = x^2 + 5x + 3
6x + y = −27
The explanation is shown below:
1. When you solve this problem you have the following solution:
x=-6
y=9
x=-5
y=3
2. As you can see the solution corresponds with the graph shown above.
3. You can give value to the variable x of the first equation and values to the x of the second equation, and plot each point obtain. You will see that the parabola and the line, touch each other at the points (-5,3) and (-6,9)</span>
