51.70
Step-by-step explanation:
Answer: x=−1 and y=4
Step-by-step explanation:
Answer:
x + 6
Step-by-step explanation:
If you dont know the value of x you cant solve the problem fully
You can use the sum and difference identities which for cosine is cos(a+b)= cosacosb-sinasinb
Answer: x > 5
Step-by-step explanation: To solve for <em>x</em> in this inequality, our goal is the same as it would be if this were an equation, to get x by itself on one side.
Since 3 is being subtracted from x, we add 3 to
both sides of the inequality to get x > 5.
When graphing x > 5, we have an open circle on 5 and the
open circle tells us that 5 is not part of our answer.
Then we draw an arrow going to the right to represent
all possible solutions to this inequality, any number greater than 5.
