4 + 2x = 7
2x = 7 - 4 = 3
x = 3/2 = 1.5 inches
        
             
        
        
        
To solve a system of linear equations graphically we graph both equations in the same coordinate system. The solution to the system will be in the point where the two lines intersect. The two lines intersect in (-3, -4) which is the solution to this system of equations
        
             
        
        
        
Answer:
a.] d) employed individuals aged 25-29
b.] a) Have your earned a bachelor's degree (or higher)?
C.] Categorical
Step-by-step explanation:
According to the scenario described, the population being studied are those aged between 25 - 29 years and who are employed. The study was to determine the level of education of the respondents who happens to fall into the category of being employed and within the 25 - 29 Years age bracket. 
The most appropriate question to ask in other to establish if respondent has at least a bachelor's degree is to explicitly ask if the respondent has a bachelor's degree or higher. 
C) Categorical : The response to the question will best directly take a 'yes' 'no' format which is a categorical label which could then be transformed into dummy variables for further analysis 
 
        
             
        
        
        
Answer:
x= -7/4
Step-by-step explanation:
8x= -14 
Divide both sides by 8 
8x/8 = -14/8
Simplify 
x= -7/4
