Let f(x) = 2x+4. If f(x) = 16, find x.

jeyben [28]

$f(x)=2x+4$

And we are given that $f(x)=16$ and want to find the value of x. Set f(x) to 16 and we get the equation:

$2x+4=16$

Subtract both sides by 4

$2x=12$

Divide both sides by 2

$x=6$

This is the answer. Let me know if you need any clarifications, thanks!

Based on the polynomial remainder theorem, what is the value of the function when x=−6 ?

Vaselesa [24]

ANSWER

$f( - 6) = 10$

EXPLANATION

The given function is
$f(x) = {x}^{4} + 8 {x}^{3} + 10 {x}^{2} - 7x + 40$

According to the remainder theorem,

$f( - 6) = R$
where R is the remainder when
$f(x)$

is divided by
$x + 6$

We therefore substitute the value of x and evaluate to obtain,

$f( - 6) = { (- 6)}^{4} + 8 {( - 6)}^{3} + 10 { (- 6)}^{2} - 7( - 6)+ 40$

$f( - 6) = 1296 + 8 ( - 216) + 10 (36) - 7( - 6)+ 40$

$f( - 6) = 1296 - 1728 + 360 + 42+ 40$

This will evaluate to,

$f( - 6) = 10$

Hence the value of the function when
$x = - 6$

is
$10$

According to the remainder theorem,
$10$
is the remainder when

$f(x) = {x}^{4} + 8 {x}^{3} + 10 {x}^{2} - 7x + 40$
is divided by
$x + 6$

Find the complete factorization of the expression. 48x + 56xy A) 8x(6 + 7y) B) 8x(7 + 6y) C) 8xy(6 + 7) D) 8xy(13)

mel-nik [20]

Hello there!

The expression:48x+ 56xy

We know we can't add them together since 56 is being multiplied by y. We aren't going to combine 48x and 56xy. They will remain separate terms.

We know that "C" and "D" are not the answers.

However, we can check the following expressions to see if they match the given expression.

8x(6+7y)= 8x*6= 48x 8x*7y= 56xy <=== "A" is correct

"A" is the correct answer.

I hope this helps!
