Answer:
subtract 2.4 from both sides, simplify to -3x=16.8, divide by -3, simplify to x=-5.6.
Step-by-step explanation:
-3x + 2.4 = 19.2
v <u>-2.4</u> <u>-2.4</u>
v 0 16.8
<u>-3x</u>=<u>16.8</u>
-3 -3
x=-5.6

Step-by-step explanation:
means the y-coordinate of the point 
that lies on 
.
Aha! Now we have a path to the solution!
We can test random values for 
, such as 
, 
, or even 
.
This leads us to drawing lines.
Answer: We draw the line 
(equivalent of testing out random points), and where it intersects the graph of ! is our answer!
(Note: it can only intersect once, otherwise it would fail the vertical line test and wouldn't be a function)
Answer:
16 ft
