The first point is (x1,y1). The second point is (x2,y2)
Since the first point is (-1, -3), we can say (x1, y1) = (-1, -3)
So ,
Since the second point is (-4, -8), we can also say (x2, y2) = (-4, -8)
So ,
Put this all together to get: , , , and </span>
Strictly speaking an equation does not have a domain. A function does. Though it may make sense to speak about a solution set to this equation over a domain.
The following could be helpful towards an answer: The equation has two sides. The left hand side is a non-linear function and the right hand side is a line with slope -1 and y-intercept of 1.
The function
has a domain over all Reals x for which it holds 
so the domain of the nonlinear function is 
.
The domain of the linear function 1-x is all Reals: 
So, together you could say the equation's solutions are defined over the domain .
Lmk if you have questions.
Answer:
5
6
Step-by-step explanation:
To solve, collect like terms
x ≥ 2 + 21/2
x ≥ 4 1/2
the whole number that would be greater than 41/2 would be 5
2. 2.7 + 3.3 > x
6 > x
The Breakeven revenue for the retail business is Birr 12,500
<h3>What is
breakeven?</h3>
Breakeven is the point at which the revenue is equals to the cost, hence the profit is zero.
Revenue = Cost
Let x represent the number of items sold, hence:
Revenue = (100% + 25%) of x = 1.25x
Cost = 5% of x + 12000 = 0.05x + 12000
At breakeven:
1.25x = 0.05x + 12000
x = 10000
Hence:
Revenue = 1.25(10000) = Birr 12,500
The Breakeven revenue for the retail business is Birr 12,500
