We have that
<span>f(x)=2x−3
g(x)=3x−7
2x-3=3x-7-------------> 3x-2x=-3+7-------> x=4
find the value of f(x) or g(x) for x=4
</span>f(x)=2x−3 -------> f(4)=2*4-3------> f(4)=5
<span>the solution is the point (4,5)
using a graph tool
see the attached figure
</span><span>statement
case a) </span><span>The solution of the equation cannot be found graphically. Esin should solve the equation algebraically.
this is not correct
case b) </span><span>The solution of the equation is the y-intercept of the linear equations.
</span>this is not correct
case c)<span>The solution of the equation is the x-coordinate of the ordered pair where the graphs of the two functions intersect.
</span>this is correct
case d) <span>The solution of the equation is the y-coordinate of the ordered pair where the graphs of the two functions intersect
this is not correct
the answer is

Given:
Height of man = 6 ft
Height of man's shadow = 11 feet
Height of building's shadow = 139 feet
To find:
The height of the building.
Solution:
We know that the heights of the objects and there shadows are always proportional.
Let x be the height of the building.
Multiply both sides by 139.
Therefore, the building is 75.8 feet long.
