Step-by-step explanation:
load=1000N
effort=250N
load arm=25cm
effort arm=?
Now,
E×E.D=L×L.D
250×E.D=1000×25
E.D=1000×25÷250
E.D=100cm
therefore,effort arm is 100cm.
A (solution) is a point of intersection. If the lines have different slopes then they will have one solution. If they have the same slope, then they will have either infinite or no solutions, depending on the y intercepts.
These equations have different slopes, therefore the system has 1 solution.
The correct answer is:
X=2
Y=4
Here's how you solve it!

Write in exponential form.


Simplify.
