Answer:
   B.  9
Step-by-step explanation:
We assume that ...
   SU = ST +TU
   133 = (9x-5) +(5x+12)
   126 = 14x . . . . . subtract 7, collect terms
   9 = x . . . . . . . . . divide by 14
 
        
             
        
        
        
Answer:
- 0.5 + 2.985i
 - 1 + 2.828i
 - 1.5 + 2.598i
 - 2 + 2.236i
 
Explanation:
Complex numbers have the general form a + bi, where a is the real part and b is the imaginary part.
Since, the numbers are neither purely imaginary nor purely real a ≠ 0 and b ≠ 0.
The absolute value of a complex number is its distance to the origin (0,0), so you use Pythagorean theorem to calculate the absolute value. Calling it |C|, that is:
Then, the work consists in finding pairs (a,b) for which:
You can do it by setting any arbitrary value less than 3 to a or b and solving for the other:

I will use b =0.5, b = 1, b = 1.5, b = 2

Then, four distinct complex numbers that have an absolute value of 3 are:
- 0.5 + 2.985i
 - 1 + 2.828i
 - 1.5 + 2.598i
 - 2 + 2.236i
 
 
        
             
        
        
        
Hello from MrBillDoesMath!
Answer:
Positive x-intercept =  + sqrt(3)
Negative x-intercept = - sqrt(3)
Discussion:
Generally, the x-intercept of a function g(x) occurs where g(x) = 0. In our case this is
g(x) = 0   =>
3x^2 - 9 = 0     =>                         (add 9 to both sides of the equation)
3 x^2      = 9    =>                         (divide both sides by 3)
x^2 = 9/3 = 3  =>
x = +\- sqrt (3)
Positive x-intercept =  + sqrt(3)
Negative x-intercept = - sqrt(3)
Thank you,
MrB
 
        
             
        
        
        
Answer:
see attached graph
Step-by-step explanation:
You graphs look fine.  The only thing I can think of without seeing the question itself, its that perhaps the teacher wants them on the same graph?
