Equatorial is a region close to the equator that is characterized by warm temperatures year-round. Hope this helps! :)
Interest rates up and bond prices down.
Higher interest rates make borrowing more expensive and thus demand from money decreases. Bond prices are inversely related to interest rates. This is a weird question because interest rates, which are set by the government, cause the change in aggregate demand not the other way around
M represents units of mass, and c2 is the speed of light squared, or multiplied by itself. it is equal to energy.
the equation says that energy and mass (matter) are interchangeable; they are different forms of the same thing.
The reason how it is related to the speed of light is that energy, be it light waves or radiation, travels at the speed of light.
Looking at this, I think the easiest (personally) way to solve it would be using the Substitution method.
Meaning we have to rearrange ONE equation, to make ONE variable ( x or y) the subject.
(1) 2.5x + y = -2
(2) 3x +2y = 0
The first equation is the easiest to rearrange. Make Y the subject for (1).
Thus,
y = -2.5x - 2
Substitute this into equation (2).
∴ 3x + 2(-2.5x - 2) = 0
Expand and simplify:
3x - 5x - 4 = 0
∴ -2x - 4 = 0
Making x the subject:
-2x = 4
x = -2
From here, we need to substitute x=-2 into equation (1) or (2) to solve for the y-value. I would say the easiest way, would be to rearrange one, to make y the subject, which was what we did earlier.
Thus,
y = -2.5x - 2
y = ((-2.5(-2) -2)
y = 3
(X,Y) x = -2, y = 3
Answer: (-2,3)
I hope you followed through.
