Step-by-step explanation:
Answer:
Let's assign the variable x to cosA. The expression then becomes x² - 5x + 6. To factorize this we need to find two numbers that have a sum of -5 and a product of 6; these numbers are -2 and -3 so the expression becomes (x - 2)(x - 3). Since we know that x = cosA the final answer is (cosA - 2)(cosA - 3).

Answer:
y = − 1
Hope this helps!
Step-by-step explanation:
Alright so this is our equation:
y − 3 = 2 ( x − 1 )
We will substitute:
x = − 1
So now our equation looks like this:
y − 3 = 2 ( −1 − 1 )
Now we will get rid of the parentheses:
y − 3 = − 2 − 2
Solve the left side:
y − 3 = − 4
Now add 3 on both sides to find out what y is:
y − 3 = − 4
+3 +3
Add:
y = − 1
Yay! We found our answer! Nice job everyone!
thats wrong the answer is 35y/3
