Step-by-step explanation:
The one point where the lines intersect is one solution. If both points are on the same line it is one solution. If the lines do not intersect it is no solution.
Given:
a.) The scale of the model is 1 in equals 47 ft.
b.) Danielle constructs a scale model of a building with a rectangular base her model is 2 inches in length and 1 inch in width.
To be able to determine the actual area of the base, let's first identify the actual dimensions of the base.
We get,
Let's now solve for the area of the base, since it is a rectangle, we will be using the formula below:
We get,
Therefore, the actual area of the base is 4,418 ft.².
The absolute value, or modulus, of a number is its distance from zero, or essentially its magnitude.
The absolute value produces a positive answer.
We have this definition for the absolute value, taking into account its different values for different signs:
Thus, for
, we split the absolute value as such:
and 
We solve each case.
and 
We check these solutions.
