Binomial theory : ( a - b ) ^3 = a^3 - 3a^2b + 3ab^2 - b^3 ;
Then, ( 2y - 3x ) ^3 = 8y^3 - 36y^2x + 54yx^2 - 27x^3
Answer:
The answer is C.
Step-by-step explanation:
You can do it by solving both equations :
y = x³ - 8
Let y=0,
x³ - 8 = 0
x³ = 8
x = ³√8
= 2
x² + 5x + 6 = 0
(x+3)(x+2) = 0
x = -3
x = -2
So the domain for 1st equation is 2 and 2nd equation is -2 & -3.
In 1st equation, the answer cannot be option A & B and in 2nd equation, the answer is B.
We need a picture in order to know the answer.

Answer:
$512
Step-by-step explanation:
His bank account started at a balance of $124.
He wrote a check, which decreased his balance by $147. His new balance is:
124 - 147 = -$23
Jeremy was then charged an overdraft fee, decreasing his balance by $32. That is:
-23 - 32 = -$55
He deposited a paycheck, which increased his balance by $567. His account balance will become:
-55 + 567 = $512
His account balance after those transactions is $512.
