Answer:
Step-by-step explanation:
Use a cofunction identity on the right hand side or left hand side...
So 
.
We have the equation:
Make the above replacement:
Since cotangent has period 180 degrees, we can also write this as:
So solving the following will give us a set of solutions for 
:
Add on both sides:
Subtract 10 on both sides:
Divide both sides by 2:
Symmetric property:
Answer:
19
Step-by-step explanation:
one third of 57 is the same as saying 57 divided by 3 and if you do that then you get the answer above
Add these eqn and then you have to cancel out (y) after that add x and 2x which is equal to 3x and also add RHS i.e.30 and divide it by 3
Answer:
#22 y=2/3x-2
#24(0,-1)(-1,2)
#25(-4,-1)(4,5)
#26(1,60)
Step-by-step explanation:
i don't know #23
Y=12x-10
Explanation:
You basically what to get y by itself so-
12x-y=10
You will add y to both sides
12x=y+10
Then subtract ten from both sides
12x-10=y or y=12x-10
