algol [13]

Answer:

(w² - 4w - 3) (w² + 4w - 3)

Step-by-step explanation:

w² + 4w³ - 3w² -4w³ - 16w² + 12w-3w² - 12w + 9

Simplify and Show all of your work please!

Fudgin [204]

Answer:

$\Huge \boxed{\mathrm{9}}$

Step-by-step explanation:

$\Rightarrow \displaystyle \frac{18 \div 2 * 3}{5-2}$

Dividing first.

$\Rightarrow \displaystyle \frac{9 * 3}{5-2}$

Multiplying and subtracting.

$\Rightarrow \displaystyle \frac{27}{3}$

Division.

$\Rightarrow 9$

For the given functions f and g, complete parts (a)-(h). For parts (a)-(d), also find the domain.

slamgirl [31]

The domain for (a) , (b) , (c) is all set of real numbers , for (d) (x ε R except x = 3/8.

The complete question is

a) (f + g)(x), (b) (f – g)(x), (c) (f × g)(x), (d) (f / g)(x), (e) (f + g)(7), (f) (f - g)(2), (g) (f.g)(3), (h) (f/g)(27)

<h3>What is a Function ?</h3>

A function is the law that defines the relation between independent and a dependent variable.

It is given that

f(x) = 3x+8

g(x) = 8x-3

(a) (f + g)(x) = 3x+8 +8x-3 = 11x+5

(b) (f – g)(x) = 3x+8 -8x+3 = -5x +11

(c) (f × g)(x) = (3x+8)(8x-3) = 24x²-9x+64x -24 = 24x² +55x-24

(d)(f / g)(x) = (3x+8)/(8x-3)

(e) (f + g)(7) = 11*7+5 = 77+5 = 82

(f) (f - g)(2)= -5*2 +11 = 1

(g) (f.g)(3) =24*9 +55*3 -24 = 357

(h) (f/g)(27) = (3x+8)/(8x-3) = (3 * 27 +8)/(8*27-3) = 89/213

The domain for (a) , (b) , (c) is all set of real numbers , for (d) (x ε R except x = 3/8)

Calculate dy/dx if Ln (x + y) = e^x/y<br> Pic included

vesna_86 [32]

The first thing you should do when dealing with implicit derivatives is to respect the rules of derivation of both the logarithm and the exponential
Then, you must regroup the terms correctly until you get dy / dx
The answer for this case is D
I attach the solution

A bucket was 7/10 full with water. After Vick washed the car, the bucket wad only 3/10 full. What fraction of the water in the b

Phoenix [80]

Hey there!

Vick had 7/10 bucket of water. . . .

She used some of the water and now has 3/10 left . . .

Subtracts the numbers 7 and 3 to solve this:

7 - 3 = 4 <----

The correct answer to your question should be 4/10 of a bucket.

Vick used 4/10 of the bucket to wash the car.

Hope this helps you.
Have a great day!
