Answer:
Well to solve this I’m gonna use substitution
So
2x-3y=-14
5x+9y=14
I‘m gonna isolate ”x” on the first equation
So it’ll be
2x-3y=-14
2x=-14+3y
x=-7+1.5y
X is -7+1.5y
Now you can subsitute into other equations to find what Y is worth
So lets use the second equation
5(-1+1.5y) + 9y = 14
Now solve for y which is -2
If you subsitute Y back in an equation you’d get -4 for x
So y = -2
and X= -4
"Vertical integration helped the Carnegie Steel business because it reduced costs along the supply chain from mining and transportation to manufacturing. Carnegie bought out coal fields, iron mines and railroad lines to ensure that he could control the raw materials and transportation lines."

Answer:
Option A)
Step-by-step explanation:
We are given the following in the question:
The rate of evaporation of rainfall drop is proportional to surface area.
Volume of rainfall drop =
Surface area of rainfall drop =
Now,
Rate of evaporation =
Equating the two values we get,
Thus, the radius radius of the raindrop decreases at a constant rate. Because the evaporation is proportional to,
Option A)
