He cause 14 blue fish and 10 rock fish
14x8=112 10x2.5=25 112+25=137
Answer:
-x^2 - 7x + 4
Step-by-step explanation:
2x(x - 1) - 3x^2 - (5x - 4)
= 2x^2 - 2x - 3x^2 - 5x + 4
Adding like terms, we get:-
-x^2 - 7x + 4 (answer).

Step-by-step explanation:
The given function is f(x) = 9·x² + 54·x - 66
The extremum of the function are found as follows;
d(f(x))/dx = 0 = d(9·x² + 54·x - 66)/dx = 18·x + 54
∴ 18·x + 54 = 0 at the maximum or minimum points
x = -54/18 = -3
Given that d²(f(x))/dx² = 18 > 0. x = -3 is a minimum point
Given that the function is a quadratic function, we have;
1) Points to the left of x = -3 are decreasing
2) Points to the right of x = -3 are increasing.
Answer: 52:3
Step-by-step explanation:
