Answer:
c
Step-by-step explanation:
x³ - y³ ← is a difference of cubes and factors as
x³ - y³ = (x - y)(x² + xy + y²)
Given
+
= - 1
Multiply through by xy to clear the fractions
x² + y² = - xy ← substitute into second factor of expansion
x³ - y³ = (x - y)(- xy + xy) = (x - y) × 0 = 0 → c
Answer:
The answer is C. 0
Step-by-step explanation:
since

we multiply both sides by xy to cancel their denominators and multiply -1 by xy
so we have

we get our answer as

we were given the difference of cubes that is

which is =

so since,

we substitute,

Answer:
4 is the correct answer
Step-by-step explanation:
y=(x+5)(x-3)
so x intercept means the value of x when y is zero
0=(x+5)(x-3)
x+5=0 so x=-5
x-3=0 so x=3
Answer:
(0-2i)(6-7i)
Step-by-step explanation:
The answer to this is pretty straightforward, as if you add a 0 to -2i, it will not change the expression.
The answer is x ≤ 2
