<em>Answer:</em>
a
<em>Step-by-step explanation:</em>
lets substitute 5 into every equation. (using 5 every time won't work every time ofc)
ok so 5(x+6)=55 would simplify into <em>5x+30=55</em> which in this case would be <em>5(5)+30=55 </em>
and 25 plus 30 (obviously) = 55
so A is the right answer

Answer:
Make coordinates with this table.
Step-by-step explanation:
What I think from these tables is that you can make coordinates with these points. Here are the instructions for you to follow-
- See the "y" and "x". These are the axis. So make coordinates with these. Ex- (0,3), (1,5) and so on
- Plot these coordinates in a graph paper.
- After plotting them, you might find the shape it made.
I hope it helps you.
Answer:

Step-by-step explanation:
we know that

Remember the identity

step 1
Find the value of 
we have that
The angle alpha lie on the III Quadrant
so
The values of sine and cosine are negative

Find the value of sine

substitute




step 2
Find the value of 
we have that
The angle beta lie on the IV Quadrant
so
The value of the cosine is positive and the value of the sine is negative

Find the value of cosine

substitute




step 3
Find cos (α + β)

we have




substitute
