Answer:
21 microwaves
Step-by-step explanation:
The net profile is equal to the income less the total cost, so the equation to the net profile NP is:
NP = 700x - (6000 + 300x)
Where 700x is the income and (6000+300x) is the cost of manufacturing.
Now, replacing NP by 2400 and solving for x, we get:
2400 = 700x - (6000 + 300x)
2400 = 700x - 6000 - 300x
2400 + 6000 = 400x
8400 = 400x
So, the least number of microwaves that must be manufactured and sold so that the net profit is $2400 is equal to 21.
Answer:
The value of a = -12.
Step-by-step explanation:
Given that the points are Q( -6, 5) and R ( -2, 3) -
As we know that-
If a line segment AB is with endpoints ( ) and (
) then the mid points C are-
<em>C = ( ,
)</em>
Here,
Q( -6, 5) and R ( -2, 3)
then the midpoints C are-
( a/3, 4) = ( ,
)
We have to find the value of x therefore we need to compare only x coordinate -
<em>a/3 = ( -6 - 2)/2</em>
<em>a/3 = -8/2</em>
<em>a/3 = - 4</em>
<em>a = -12</em>
Hence the value of a = -12.
