Answer:
choosing to spend one more hour studying economics because you think the improvement in your score on the next quiz will be worth the sacrifice of time.
Explanation:
Marginal thinking: In economics, the term "marginal thinking" is described as a process that requires or needs the "decision-makers" to figure out whether the profit related to one or more than one unit of something is considered as greater than its actual cost.
In other words, it described the process that states the number of extra resources that are being considered as worth.
The mountain ranges of Apennine and Alps has an arc shape which tightens the northern boundaries of Italy against any possible foreign invasion and influences. The rivers are also found in the mountain regions of Italy where it distributes water.
Let x and y are the integers.
the product of two integers x and y = (x)(y) = 9
and their sum = x + y = -6
y = -6 -x
now put the value of y in the product equation;
(x)(-6-x) = 9
-6x - x² -9 = 0
x²+6x + 9 = 0
x² +3x +3x + 9 = 0
x(x+3) + 3 (x+3) = 0
(x+3)(x+3) = 0
so, x+3 = 0
x = -3
So, the two integers are -3 and -3
if we multiply -3 and -3 we get answer 9
and if we add -3 and -3 we get answer -6.
Because this is one of the ways we communicate with our children and what you put out in the universe is what you get back from,the universe
