Answer:
the graph in the attached figure
Step-by-step explanation:
we have

isolate the variable y
Subtract 7x both sides


Divide by 3 both sides

The solution of the inequality is the shaded area below the dashed line
The equation of the shaded line is 
The slope of the dashed line is negative 
The y-intercept of the dashed line is the point 
The x-intercept of the dashed line is the point 
To graph the inequality plot the intercepts and shade the area below the dashed line
using a graphing tool
the graph in the attached figure
Answer:
Step-by-step explanation:
So you have to get 2/3 of 128 grams which is about 85 grams. It says she has to mix 64 grams so she went over.
Hope this helps :)
Using the same numbers u started out with
9c + 4 = 49
