Answer: FIRST OPTION.
Step-by-step explanation:
First, it is important to remember that the Slope-Intercept form of the equation of a line is the shown below:
Where "m" is the slope of the line and "b" is the y-intercept.
By definiton, given a System of Linear equations, if they are exactly the same line, then the System of equations have Infinely many solutions.
In this case you have the following System of Linear equations given in the exercise:
So, since you need the system has Infinite solutions, you know that the slope and the y-intercept of both lines must be equal.
Therefore, you can identify that the value of "a" and "b" must be the following:
So the Linear System would be the shown below:
The given area of the ft. by 33 ft. wall less the areas of the Windows and the Door give the area of the painted part of the wall as
ft.²
The area of the painted part of the wall is ft.²
The given dimensions of the wall are;
The width of the wall = ft.
The height of the wall = 33 ft.
The painted area = Area of the wall - (Area of the widows + The door)
Which gives;
The area of the painted part of the wall is ft.²
