Answer:
x>-9
Step-by-step explanation:p
1.) Subtract 1 from both sides
-2/3x+1<7
-1<-1
= -2/3x < 6
2.) Multiple the 3 (denominator) in order to get rid of the fraction
3(-2/3x) < (6)3
= -6/3x < 18 (simplify the 6/3 into 2)
= -2x < 18
3.) Divide by -2 (when you divide with a negative number, your sin is going to switch, meaning it will turn into a '>' sign)
-2x / -2 < 18/-2
= x > -9

If you want to graph it on a number line, it would look something like the picture above. (the circle is open because it doesn't have the line underneath. You're symbol also indicates which way you shade!! < = left .....> = right.....think of them like arrows :) )
Answer:
I love algebra anyways
the ans is in the picture with the steps
(hope it helps can i plz have brainlist :D hehe)
Step-by-step explanation:
Answer:
Step-by-step explanation:
It's very simple. First you find the derivative of the function, then simplify by rationalizing the denominator and multiplying by 4-i. You should then get your answer.
The period of is .
Recall that and both have periods of . This means
Replacing with , we have
In other words, if we change by some multiple of , we end up with the same output. So has period .
Similarly, has a period of ,
We want to find the period of , such that
On the left side, we have
and
So, in terms of its period, we have
and we need to find the smallest positive such that
which points to , since
