No hay explanation
Now before taking the inverse tangent of both sides, recall that
where
is any integer. This means that when taking the inverse tangent of
, instead of just
, we would end up with
So after doing so in the equation above, we're left with
As
can be any integer, including negative integers, we can simply write
Keeping in mind that, there are 12 months in a year, therefore, 7 months is really just 7/12 of a year.
Answer:
x=-25
Step-by-step explanation:
1. Add -15 to both sides
50=-2x
2. Divide -2 to both sides
-25
Final Answer:
-25
(Let me know if you still don't understand
First we have to simplify
3r + 2 < 5
subtract 2 from each side then divide by 3
r < 1
7r - 10 > 60
add ten to both sides. divide by 7.
r > 10
answer: r<1 or r>10
if you have to graph, you should have a number line going from 0 to 11. You should put an open circle on 1 and an open circle on 10. Shade to the left from the open circle on 1, and then shade from the right from the open circle on 10.
Your union should look like this:
(-♾, 1)U(10,+♾)
