Answer: 
x=-3.5
reason:
first, add 3 to both sides
this makes the equation -1/2x=7
then, divide both sides by -1/2
this will give you x=-3.5

<span>the correct equation is
- 4j² + 3j - 28 =0
 ax² + bx + c, 
 a = -4, b=3  c =- 28.
The discriminent D = b² - 4.a.cD = 3² - 4(-4)(-28)D = -439 
If D ≥ 0 there are either 2 roots or one double if = 0)if D< 0, there are no real roots (but 2 imaginary roots)Since D < 0, then there is no real roots
 The answer there is no real roots</span>
        
             
        
        
        
Answer:
100 degrees 
Step-by-step explanation:
measure of FHD = 65 + 35
measure of FHD = 100
        
                    
             
        
        
        
Answer:
C.) 2
Step-by-step explanation:
<em>You must use the pythagorean theorem</em>
the distance on the x axis (or a) is 6
the distance on the y axis (or b) is 10
 = 136
 = 136 
 = 2
 = 2
