From equation 1 e=23-6f
sub 1 into 2. 2(23-6f)-f=7
46-12f-f=7
46-7-12f-f=0
39-11f=0
39=11f
then u divide both side by 11
therefore f=3.55
subtitude f in 1
6(3.55)+e=23
21.3+e=23
e=23-21.3
e=1.7

What is the solution to the system graphed below?

Feliz [49]

Answer:

Option D.

Step-by-step explanation:

We need to find the solution to the system graphed below.

If a system of equation have 2 linear equation then the intersection point of both lines lines is the solution of the system of equations.

In the given graph two straight lines intersect each other at (-1,-1).

Point of intersection = (-1,-1)

So, by using the given graph we can conclude that the solution of given system of equations is (-1,-1).

Therefore, the correct option is D.

1.) What is the equation of a vertical line passing through the point (2, -4)?

Bezzdna [24]

The points lying on a vertical line share the same $x$ coordinate. Similarly, the points lying on a horizontal line share the same $y$ coordinate.

So, vertical lines are identified by the $x$ coordinate of their points, and have an equation like $x=x_0$ , where $x_0$ is a fixed real number.

Similarly, horizontal lines are identified by the $y$ coordinate of their points, and have an equation like $y=y_0$ , where $y_0$ is a fixed real number.
