The equilibrium referred to here is the dynamic equilibrium. It means that there is a change happening, but the opposite change are equal so they cancel out. So, we can determine the equilibrium price at the point where the demand and supply curve intersect. That would be at the quantity of 60 units. Therefore, the equilibrium price is $10.
A reasonable estimate for 8.24 divided by 4 would be 2. This would be a reasonable estimate because .24 rlly isn’t all that much so you are able to round down to 8. (Hope that’s right!)
4x−5=7+4y
subtract 7 from both side
4x - 5 -7 = 4y
4x -12 = 4y
divide by 4
4x/4 -12/4 = 4y/4
x-3=y
The correct answer would be A) X^6 Y^5
I think the answer may be D. You can graph the points and draw a line through the points to see what other points are intersected by the line.
