To solve the equation 2x−3=3x−7 , Esin graphs the functions f(x)=2x−3 and g(x)=3x−7 on the same set of coordinate axes.
1 answer:
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
</span>case c) The solution of the equation is the x-coordinate of the ordered pair where the graphs of the two functions intersect.

Answer:
Step-by-step explanation:
Given
below sea level
Sea of Galilee = 30 times Lowest in Lammefjord, Denmark
Required
Determine the elevation of the Sea of Galilee
We have that the lowest elevation in Lammefjord is:
It is negative because, the elevation is below sea level.
Calculating the elevation of Sea of Galilee, we have:
Sea of Galilee = 30 times Lowest in Lammefjord, Denmark
<em>Hence, the elevation of Sea of Galilee is -690ft or 690ft below sea level</em>
