Answer:
x = -4
Step-by-step explanation:
16 = -4x (divide both sides by -4)
-4 = x
or
x = -4
Solve the inequalities just like a normal equation
y - x > 0
y > x which means that everything in the graph should be filled in above the line y = x
x + 1 < 0
x < -1
so everything left of the vertical line x = -1 should be filled in

Answer:
x² - 16xy + 64y²
Step-by-step explanation:
The difference of x and 8y is x - 8y
The square of the difference is (x - 8y)² = (x - 8y)(x - 8y)
Expand by multiplying each term in the second factor by each term in the first factor, that is
x(x - 8y) - 8y(x - 8y) ← distribute both parenthesis
= x² - 8xy - 8xy + 64y² ← collect like terms
= x² - 16xy + 64y²
