For the answer to the question above, the power of "y" doesn't influence descending order for x even if it is higher than power of x.
Unordered polynomial is
7x3y3 + 4 - 11x5y2 - 3x2y
Polynomial in descending order looks like this
-11x5y2 + 7x3y3 - 3x2y + 4
Degree of the second term is 5 ( because of x5 )
Answer:
x = 9
y = 9
Step-by-step explanation:
Given :
Let :
Kenyan French roast coffee = x
Cost per x = $8
Sumatran Coffee = y
Cost per y = $10
x + y = 18 - - - - (1)
8x + 10y = 9 * 18 ;
8x + 10y = 162 - - - - (2)
From (1):
x = 18 - y
Put x = 18 - y in (2)
8(18 - y) + 10y = 162
144 - 8y + 10y = 162
2y = 162 - 144
2y = 18
y = 9
x = 18 - y
x = 18 - 9
x = 9
