Answer:

Step-by-step explanation:

Hello, please consider the following.

$x^4+xy^3+x^3+y^3\\\\=x^3*x+x*y^3+x^3+y^3\\\\=x(x^3+y^3)+x^3+y^3\\\\\boxed{=(x+1)(x^3+y^3)}\\$

18. Determine the greatest three-digit number in each of the

katen-ka-za [31]

If you're asking about the largest number that can be written with 3 digits in the given base:

• In base 2, the largest number with 3 digits is

111₂ = 1•2² + 1•2¹ + 1•2⁰ = 7

• In base 12, the largest number with 3 digits is

bbb₁₂ = 11•12² + 11•12¹ + 11•12⁰ = 1727

(in base 12, a₁₂ = 10 and b₁₂ = 11)

Find the inverse function of y=(x-2)^2 + 3. please show steps

Lunna [17]

Answer:

$f^{-1}(x)=2\pm\sqrt{x-3}$

Step-by-step explanation:

we have

$y=(x-2)^2+3$

step 1

Exchange the variables (x for y and y for x)

$x=(y-2)^2+3$

Isolate the variable y

step 2

$x=(y-2)^2+3$

subtract 3 both sides

$(y-2)^2=x-3$

step 3

square root both sides

$y-2=\pm\sqrt{x-3}$

step 4

Adds 2 both sides

$y=2\pm\sqrt{x-3}$

step 5

Let

$f^{-1}(x)=y$

$f^{-1}(x)=2\pm\sqrt{x-3}$
