A+2b=3000
90a+60b=150000
-90a-180b=-127000
90a+60b=150000
-120b=-120000
b=1000
a+2000=3000
a=1000
crop a=1000
crop b=1000
2*(4+y)
The answer is c.
Its two times the sum so two is on the outside and 4 and y come after the word sum so its addition.
Let's work on the triangle first. The x intercept of 2y=27-3x is
0 = 27 - 3x
3x = 27
x = 9
So A(9,0)
B is the meet of 2y=27-3x and y=3x
2y=27-y
3y=27
y=9
y is the height of OAB; we don't really need x
Area(OAB) = 
Now we have to subtract
Area = 40.5 - 24.3 = 16.2
Answer: 16.2
We will investigate how to determine the constant of proportionality for specific relationship between two variables.
We are given the respect proportionality between two variables ( x and y ) on a cartesian coordinate plane as such:

We are to determine the constant of proportionality ( k ) for the relationship expressed between the two variables.
A general proportional relation between ( x ) and ( y ) is expressed as follows:

Where,

We will use the given data point ( x , y ) and the general expression for direct proportions to determine the value of the constant of proportionality ( k ) as follows:

We plugged in the respective quantities of the variables ( x ) and ( y ) and evaluated for the constant of proportionality ( k ):
