Answer:
Step-by-step explanation:
Generally, the single variable on the left side of the equation is the "output" or dependent variable, while any other variables on the right side of the equation are considered to be independent variables, or "input."
So, we assume your first question is asking for the value of t that makes w=176. Put the values in the equation and solve for the unknown.
   w = 112 +8t
   176 = 112 + 8t
   64 = 8t . . . . . . . subtract 112
   8 = t . . . . . . . . . divide by 8
The input for an output of 176 is 8.

Ordered pairs are always written as ...
   (input, output)
So, (4, 144) means the output is 144 for an input of 4.
 
        
                    
             
        
        
        
The correlation coefficient is a number that indicates the direction
and closeness of points of a line of best of fit.
So it tells us two things.
It tells us the direction of the line of best fit
and it tells us the closeness of the points.
Usually, anything between -0.9 and -0.6 has a moderate negative correlation. If you look at this on a graph, you will notice that the points definitely resemble a line so we say it's moderate.
It will be a negative correlation because the slope is negative. 
 
        
                    
             
        
        
        
Answer:
4
Step-by-step explanation:
Divide 28 by 4 to get 7
 
        
             
        
        
        
The domain is set of x-value. 
Therefore, the domain of the relation Domain of R = {3,1,-1}
 
        
             
        
        
        
The Distributive Property. You are distributing a to x + y.
Hope this helps!
