Answer:

(x - y)(x² + xy + y²)

Step-by-step explanation:

Since both are cubed (³),

we can apply the Difference of Cubes Formula:

A binomial that is of the form (something)³ – (something else)³

To factor any difference of cubes,

the formula a³ – b³ = (a – b)(a² + ab + b²).

hence, x³ - y³ = (x - y)(x² + xy + y²)

U=F(r+B) solve for r

irina1246 [14]

<h2>The value of r = $\dfrac{U-FB}{F}$ </h2>

Step-by-step explanation:

We have,

U = F(r + B)

To find, the value of r = ?

∴ U = F(r + B)

Dividing both sides by F, we get

$\dfrac{U }{F}=\dfrac{F(r+B) }{F}$

⇒ $\dfrac{U }{F}$ = r + B

⇒ r + B = $\dfrac{U }{F}$

⇒ r = $\dfrac{U }{F}$ - B

⇒ r = $\dfrac{U-FB}{F}$

∴ The value of r = $\dfrac{U-FB}{F}$

P(x)= 3x; find p(-6)

just olya [345]

<u>Answer:</u>

$\bf -18$

<u>Step-by-step explanation:</u>

$p(x) = 3x$

In order to find $p(-6)$ , we have to replace the $x$ in the definition of $p(x)$ with $-6$ :

$p(-6) = 3(-6)$

= $\bf -18$

Does this graph represent a function? Why or why not?

malfutka [58]

Answer:

Yes.

Step-by-step explanation:

It is a function because it passes the vertical line test. Each x-value has just one y-value. If the relation had any x-values that had several y-values, it would just be a relation. But this one is a function.

Hope this helps!
