Answer x=1/5
6x-3=-9x
-3=-15x
-3/-15x=1/5
Answer:
x^2-11/-8x
Step-by-step explanation:
We can solve this equation easily by using PEMDAS, or order of operations.
<u>Parenthesis</u>
<u>Exponents</u>
<u>Multiplication>Division (Depends on which comes first left to right)</u>
<u>Addition>Subtraction (See multiplication>division)</u>
Now that we know the order of the operations, we can solve.
First, we cant solve for x^2 because we dont know the value of x, so well leave that alone. Same with 22/x. All we can do is use the commutative property.
So our equation is now x^2-11/-8x
Hope this helps!
Then using trygonometric table or a graph we read that:
Period of cosinus function = 2π
So the last answer is
