Answer: The required distance between the top and bottom of the bridge is 76 feet.
Step-by-step explanation: Given that a new bridge structure requires triangles that are in a ratio of 1:1.
AC = 2x + 10 and EC = 4x − 18.
We are to find the distance between the top and bottom of the bridge, in feet.
Since the two triangles ACB and DCE are in the ratio 1 : 1, so their corresponding sides are also in the ratio 1 : 1.
The sides AC and EC are corresponding to each other, so we must have
Therefore, the distance between the top and bottom of the bridge is
Thus, the required distance between the top and bottom of the bridge is 76 feet.
3^-2 is the same as 1/3^2
3^2 = 9
1/9
3^-2 = 1/9

Given:
The graph of a line.
To find:
The equation for the given line.
Solution:
From the given graph, it is clear that the line passes through the points (0,-5) and (5,0). So, the equation of the line is:
Subtract 5 from both sides.
Therefore, the equation of the given line is .
