Answer:
The equation has no solution; therefore, the system of equations has no solution
Step-by-step explanation:
we have
 -----> equation A
 -----> equation A
 -----> equation B
 -----> equation B
we know that
If after applying the linear combination method, Heather arrived at the equation 0 = 60
then 
The reason is because both lines are parallel, therefore the system of equations has no solutions
<u>Verify</u>
isolate the variable y in the equation A

 --------> the slope is 1/3
 --------> the slope is 1/3
isolate the variable y in the equation B


 --------> the slope is 1/3
 --------> the slope is 1/3
Remember that
If the slopes are equal the lines are parallel
so
The system of equations has no solutions

Answer:
For packages of 8 = 
Each package of Buns contain 8 pieces.
Therefore 100 barbecue will be contained in 100/8 = 12.5 packages
For packages of 12 = 
Each package of Buns contain 12 pieces.
Therefore 100 barbecue will be contained in 100/12 = 8.3 packages
 
        
             
        
        
        
Answer:

Step-by-step explanation:
We would have to convert the standard equation into slope-intercept form.
======================================
<h3><u>Converting the equation into Slope-Intercept Form:</u></h3>
<u />
======================================
<h3><u>Identifying the Slope and Y-Intercept:</u></h3>
<em>General slope-intercept form is: </em>
<em></em>
<u />
In the equation  ,  '-2' would be the slope since it is in 'm's place, and '3' would be the y-intercept since it's in 'b's place.
,  '-2' would be the slope since it is in 'm's place, and '3' would be the y-intercept since it's in 'b's place.
<em>Therefore:</em>
<em></em> <em></em>
