Answer:
The number of pounds of City Roast Columbian coffee they should buy is 1 and the number of pounds of French Roast Columbian coffee they should buy is 11.
Step-by-step explanation:
Let
x ----> the number of pounds of a City Roast Columbian coffee
y ---> the number of pounds of a French Roast Columbian coffee
we know that
-----> equation A
----> equation B
Solve the system of equations by graphing
The solution is the intersection point both graphs
The solution is the point (1,11)
therefore
The number of pounds of City Roast Columbian coffee they should buy is 1 and the number of pounds of French Roast Columbian coffee they should buy is 11.
Y=3x-13 x=-2y-11 that’s elimination answers for both

Answer:
D. Graph D
Step-by-step explanation:D. Graph D
Step-by-step explanation:
We know that, 'Direct Variation or Directly Proportional' is relationship between two variables where one is a constant multiple of the other.
That is, if one variable changes, the other variable also changes in proportion to the first variable.
The general form of 'Direct Variation' is y = kx, where k is a constant i.e. it does not have a y-intercept.
Now, according to our options, we see that the figures of A,B,C are the graphs of the straight lines given by y =-2x+2 , y=2x+2, y=-2x+2 respectively.
Each of these three equations have y-intercept, therefore cannot be the equations of a direct proportion.
Now, in option D, the figure is the graph of straight line y = -x and has no y-intercept.
Hence, the linear function in Graph D shows a direct proportion.
