This is for 2.X=22 so the total angle is 90° and you take away 68° and that leaves you with 22°
The symbol "<=" without quotes means "less than or equal to"
-6x + 2y <= 42
-6x + 2y + 6x <= 42 + 6x ... Add 6x to both sides
2y <= 6x + 42
2y/2 <= 6x/2 + 42/2 ... divide every term by 2
y <= 3x + 21
So the answer is choice D
Answer:
3-7 is negitive 4 in your answer it's 3-7 = -4
Step-by-step explanation:
It's negitive four because if you subtract you will get 4 but since it's other way around. And if you do It, it will say that even if there is no negitive sign it won't change the problem because it's still the same problem.
1) 3 - 7
2) there are 3 ways to do this to get the answer:
1) 3/7
2) 7 + 3 - 4 + 3
3) now 7 + 3 is ten - 7 is 3 + 4 is 7, so then if you do 3 - 7 you get negitive four
4) now check your answer by subtracting 3 and 7
5) then you get -4
btw: ( hope this helped :) )
