Step 1: Draw the mapping diagram for the given relation.
Step 2: A relation is a function if each element in the domain is paired with one and only one element in the range.
Step 3: From the mapping diagram, it can be observed that the given relation is not a function as '3' in the domain is paired with two elements - 1 and - 2 in the range and '6' is paired with - 1 and - 2.

 Domain Range
 3 | -1
|
|
 6 | -2

The steps taken to solve this system of equations would first be:

1. Sub 4x-2 into your first equation, 2x+5(4x-2)= 12 ->

2. Solve/simplify this equation to get x=1

3. Sub x=1 into your second equation and solve for y = 2

4. Get the solution (1,2)

Using trigonometry ratio

$\sin 37^0=\frac{167}{x}$ $\begin{gathered} 0.6018\text{ = }\frac{167}{x} \\ 0.6018x\text{ = 167} \\ x\text{ = }\frac{167}{0.6018}\text{ = 277.5ft} \end{gathered}$

x = 277.5 ft

Answer: The length of the bottom left side is 14.

To find the length of this side, we need to know the relationship between the different sections when chords cross each other.

The relationship is that if you multiply the 2 parts of each chord together, it will equal the product of the two sides in the other chord.

Our equation can be written as:

7(8) = 4(x)
56 = 4x
14 = x
