1) y = 8 x = 7.5
2) y = 3 x = 12
Answer:
1st one is 9x-2
2nd is -3x -2
3rd one (put 1 instead of x in the given functions then calculate values and multiple )6
Answer:
Line 3.
Step-by-step explanation:
The mistake is in line 3.
' s equals fraction numerator negative 10'.
It should be - (-10) = 'positive 10'.
The answer is 1:13 you have to divide

Step-by-step explanation:
How you find co-terminal is by adding or subtracting 360 degrees to the value you are given.
If it is a positive number like #18. all you do is subtract 510 - 360 = 150 until you get to a value between 0 degrees and 360 degrees.
The same thing applies to negative numbers. Like #21. You will add 360 + (-660) until you get to a number between 0 degrees and 360 degrees.
-660 + 360 = -300 (this is not a value in between 0 and 360 so we must add 360 again)
-300 + 360 = 60 (this is a value in between 0 and 360) (this is the co-terminal angle)
That is the idea of finding co-terminal angles.
