A) 2007
b) 120
c) the donations are decreasing as years increase
Answer:
x²+4=0
Step-by-step explanation:
x²=-4
√x² = √-4
x = 2i
x is an imaginary number
Let:
x = Pastries ordered
y = Cost of order

For each pastry Cole ordered, the cost of the order increased by a fixed amount of $1.55
5x - y³ = 135x - y³ = 13
The answer can be obtained by simply putting the ordered pair into the equations. First (2 , -9)
5(2) - (9)³ = 135(5) - (-9)³ = 13
10 + 729 = 675 + 729 = 13
739 = 1404 = 13
This is not true. Therefore this is not a solution
Second (3,-6)
5(3) - (-6)³ = 135(5) - (-6)³ = 13
231 = 891 = 13
This is also not true
Therefore, neither ordered pair is a solution.
