Answer: (f•g)(x) = (15 + x)/x

Explanation:
F(x) = 5/x and g(x) = 3 + x/5

Then (f•g)(x) = 5/x • 3 + x/5

(f•g)(x) = 5/x • 15/5 + x/5

(f•g)(x) = 5/x • (15 + x)/5

(f•g)(x) = 5(15 + x)/5x

(f•g)(x) = (15 + x)/x

The polynomial of degree 3, P(x), has a root of multiplicity 2 at x=4 and a root of multiplicity 1 at x=−2. The y-intercept is y

Sedbober [7]

Answer:

Step-by-step explanation:

P(x) = a(x - 2)2(x + 4), a ≠ 0

Use the given point (0,-10) to find a.

-10 = a(0 - 2)2(0 + 5) = a(4)(5) = 20a

a = -10/20 = -1/2

P(x) = (-1/2)(x - 2)2(x + 5)

You can expand this if you wish

×-2+2×+4+2×-2=180 what does x equal in this equation.

daser333 [38]

Answer:

x = 36

Here's how I got that:

- Group like terms -

x - 2 + 2x + 4 + 2x - 2 = 180

↓

5x - 2 + 4 - 2 = 180

↓

5x = 180

- Divide both sides by 5 -

5x/5 = 180/5

↓

x = 36

~ That's all folks ~
