Both Ants start at the origin. Which means they will move the same distance even if they are going opposite waves
        
                    
             
        
        
        
B = 5
Because you must subtract like terms first:
B+9=14
 -9 -9
 = =
 0 5
So, B = 5

Answer:
Step-by-step explanation:
Part A 
2x-3y =21 in slope-intercept form is y=2/3x-7 one you graph the equation it would be a parallel to the equation shown above so there are no intersections
PART B
y=1/3x^2 and y= 2/3x - 5
1/3x^2 = 2/3x-5
1/3x^2=2/3x-5
then u multiply everything by 3
1/3x^2*3 =2/3x *3-5*3
the three for 1/3*3 cancels out so you are left with
1x^2= 2x -15
1x^2-2x+15=0 
You can not factor it and well i guess there is no intersection
im sorry if i got this wrong bc i had a similar question just different numbers and i tried to solve this one the way i sloved mine so im not sure of my answer for part b
