Answer:

Let us assume cost of each pineapple cake = $x.

Cost of each chocolate cakes = $y.

On weekdays 45 pineapple cakes and 62 chocolate cakes were sold.

Total cost of 45 pineapple cakes and 62 chocolate cakes were sold = $3,520.

Therefore, first equation would be

45x + 62y = 3520 --------------equation(1).

On weekends 55 pineapple cakes and 79 chocolate cakes were sold.

Total cost of 55 pineapple cakes and 79 chocolate cakes were sold = $4,415.

Therefore, second equation would be

55x + 79y = 4415 --------------equation(2).

Therefore, system of equation are 45x + 62y = 3520 and 55x + 79y = 4415.

And we can form a matrix as

I can see why your confused, but the range of the function is y≤−1 or y≥1 . The graph of the cotangent function looks like this: The domain of the function y=cot(x)=cos(x)sin(x) is all real numbers except the values where sin(x) is equal to 0 , that is, the values πn for all integers n .

Hope this helps

Have a great day!
