Answer:
Step-by-step explanation:
Given the inequality
|x|> 1
The modulus of x shows that x can be both positive and negative value.
If x is positive:
x>1
1<x
If x is negative:
-x>1
Multiplying both sides of the inequality by minus will change the inequality sign
x < -1
Combining both inequalities:
1<x<-1
Find the position on the number line in the attachment
Selling price of app per user = $10 per month
Total no. of user in first month = 10
To tal no. of user added per month = 7
We have to find how much money is earned in one year
So the formula is n/2 * (2a +(n-1)d)
Here we have n = 12 which is total no. of months
a = 100 , which is money earned in one month
d = 70 , which is increase in money earned per month
So money earned in a year comes out to be 5820
The expression which is equivalent to √(-9) is 3i.
<h3>What is Complex number?</h3>
A complex number is the sum of a real number and an imaginary number. A complex number is of the form a + ib and is usually represented by z.
Here, given expression;
y = √(-9)
y = √9 X √(-1)
y = 3√(-1)
y = 3i
Thus, the expression which is equivalent to √(-9) is 3i.
