Everett and marie are going to make brownies for their family reunion. they want to make 4 times the amount the recipe makes. if the recipe calls for 2/3 cup of oil, how much oil will they need?

the 3rd on is correct

step-by-step explanation:

option a is correct.

only one solution to the system of equations

step-by-step explanation:

if the graph of the equations do not intersects(i.,e if they are parallel) then, there are no solutions that are true for both the equations.

if the graph of the equations intersects, then there is one solution and that is true for both the equations.

since, in the given figure:

the two lines intersect each other

⇒there is only one solution which satisfy both the lines of an equations.

therefore, there is only one solution to the system of equation
