Answer:
Step-by-step explanation:
1. 3x2 + 5x - 4 + 6x2 - x + 7
= combining like terms
= 9x2 + 4x + 3
2. 2y2 - 3y + 6 + y2 - 5y - 1 + (-4) + 2y2 - 2y
= 5y2 - 10y + 1
3. 2x2y - 3xy2 + x2y - 4x2y - 2xy2
= - x2y - 5xy2
4. x2 - y2 + 2x2 - 3xy + 4y2 + 3y2 - 5xy - x2
= 2x2 - 8xy + 6y2
A complex number is made of two parts: one real part (without i) and one imaginary part (with i).
The conjugate of a complex number is found by inverting the sign of the imaginary part of the number.
Therefore, the conjugate of 10+3i is 10−3i

The r variable is correct. This is because the control variable is the one that stays the same all the way through the experiment.
A graphical solution shows the objective function is maximized for (x, y) = (5, 1). The corresponding value of p is
p = 3
