Answer:
C
Step-by-step explanation:
The expression given is a difference of cubes and factors as
a³ - b³ = (a - b)(a² + ab + b²)
8
= (2
)³ ⇒ a = 2
27
= (3y²)³ ⇒ b = 3y²
Hence 2 factors are
(2
- 3y²) and
((2
)² + (2
× 3y²) + (3y²)²)
= (4
+ 6
y² + 9
)
Hence the factored form of the expression is C
F(x) - g(x) = -2x^3 - 6x^2 + 9x
1 dimes are worth 10 cents.
Multiply.
6 * 10 = 60
Put in a fraction with the denominator given.
60/100
Reduce the fraction.
60/100
30/50
15/25
3/5
Best of Luck!
Answer:
(a variation of) vertex form
Step-by-step explanation:
For vertical scale factor "a" and vertex (h, k), the vertex form of the equation for a parabola can be written as ...
y = a(x -h)^2 +k
If k is subtracted from this equation, an alternate form is ...
y -k = a(x -h)^2
This latter version of vertex form is the form your equation has, where ...
