Answer:
b) 

Step-by-step explanation:
b) set up equations so they are equal to each other,



this is when f(x)=g(x) so our approximation was close.
c)solving it graphically is nearly impossible because the solution can be any value around the intersection. only way to be sure is to solve it symbolically.
 
        
             
        
        
        
Answer:   C. (-4, -2)
<u>Step-by-step explanation:</u>
First, eliminate one of the variables and solve for the remaining variable:
2x - 5y = 2      →    3(2x - 5y = 2)      →     6x - 15y = 6
3x + 2y = -16   →  -2(3x + 2y = -16)    →  <u> -6x - 4y = 32</u>
                                                                      -19y = 38
                                                                          y = -2 
Next, replace "y" with -2 into either of the original equations to solve for x:
2x - 5y = 2
2x - 5(-2) = 2
2x + 10 = 2
2x         = -8
  x          = -4
                                        x = -4,  y = -2
<u>Check:</u>
Plug in the x- and y-values into the other original equation:
3x + 2y = -16
3(-4) + 2(-2) = -16
 -12  +  -4     = -16
       -16         = -16
