To solve such problems we need to know about the system of equatons.

<h3 /><h3>System of Equation</h3>

When the lines of the system of the equation are parallel to each other the system of equations has no solution.

Two lines are parallel lines if they have the same slope and different y-intercept.

<h3>Given options</h3>

A.)  x – y = 1, –3x+3y = 3

B.)  2y = 3 – 4x, x+y = 0

C.)  12x+2 = 4y – 10, 2x+y = –11

D.)  –3x – y = 5, 15x = 10 – 5y

E.)   x+y = 1, –4x+2y = 7.

<h3 /><h3>Solutions</h3>

A.) x-y=1, -3x+3y = 3

The two lines when plotted on the graph will give two parallel lines. the graph is been plotted below in image(A).

therefore, the system of equations has no solution.

B.) 2y = 3 – 4x, x+y = 0

The two lines when plotted on the graph will give a point of intersection. the graph is been plotted below in image(B)

therefore, the system of equations has a unique solution.

C.) 12x+2 = 4y – 10, 2x+y = –11

The two lines when plotted on the graph will give a point of intersection. the graph is been plotted below in image(C)

therefore, the system of equations has a unique solution.

D.) –3x – y = 5, 15x = 10 – 5y

The two lines when plotted on the graph will give two parallel lines. the graph is been plotted below in image(D).

therefore, the system of equations has no solution.

E.)  x+y = 1, –4x+2y = 7

The two lines when plotted on the graph will give a point of intersection. the graph is been plotted below in image(E)

therefore, the system of equations has a unique solution.

Describe the end behavior of the function. f(x)=x^3+11x^2+35x+30
Lelechka [254]
To determine end behavior, we only have to look at the leading term.

First, the leading term is positive, so we won't have to negate anything.

The leading term has a power that is odd.

Since the exponent is odd, this means that the function goes to positive infinity as x goes to positive infinity.

This also means that the function goes to negative infinity as x goes to negative infinity.

Those are the end behaviors.

Have an awesome day! :)
