Answer:

C. 2x-4y=0 and 7x-6y=-24

Step-by-step explanation:

We are given the graph of the system of equations given by,

y=\frac{x}{2}

y=\frac{7x}{6}+4.

After simplifying the equations, we get,

y=\frac{x}{2} i.e. 2y=x i.e. 4y=2x i.e. 2x-4y=0

And,

y=\frac{7x}{6}+4 i.e. y-\frac{7x}{6}=4 i.e. 6y-7x=24 or 7x-6y=-24

Hence, we get the system of equations,

2x-4y=0 and 7x-6y=-24

Now, we will check the point of intersection of the new equations,

Multiplying first equation by 7 and second equation by 2 and then subtracting both equations,

We get,

14x-28y-14x+12y=48 gives -16y=48 i.e. y = -3

So, 2x-4y=0 gives 2x-4×(-3)=0 i.e. 2x=-12 i.e. x= -6

Thus, the intersection point is (-6,-3).

So, the new system of equation matches the graph.

Hence, option C is correct.

He graph of the function f(x) = –(x + 6)(x + 2) is shown below.
Molodets [167]

The domain of the function is all real numbers, the range of a function is y ≤ 4

<h3>What is a function?</h3>

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have a function:

f(x) = –(x + 6)(x + 2)

If we plot this function on the coordinate plane, we will see it is a graph of a quadratic function.

Here the no other details are given.

But we can say:

  • The domain of the function is all real numbers.
  • The range of a function is y ≤ 4
  • The x-axis intercept will be at (-6, 0) and (-2, 0).

Thus, the domain of the function is all real numbers, the range of a function is y ≤ 4
