Answer:

A = 2

D = 1

B = 4

C = 3

Step-by-step explanation:

Height of water in bathtub is a function of water in bathtub.

P(t) = w ; t = time ; w = height of water.

A: P (0)=0 ; At time, t = 0 ; height of water = 0, there is no water on bathtub

2: The bathtub starts out with no water.

D: P (20) = 0 ; At time, t = 20 ; w = 0 ;the tub is empty.

1: After 20 minutes, the bathtub is empty.

B:P (4)= 10 `; At t = 4, w = 10 ; height of water in bath tub is 10

4: The height of the water is 10 inches after 4 minutes

C:P (10) = 4 ; At t = 10, w =4, height of water in bathtub = 4 inches

3: After 10 minutes, the height of the water is 4 inches.

HOTS Question:<br>Solve: 2xy /x+y = 3/2, x+y≠0 and xy / 2x-y = -3 / 10, 2x-y≠0

andreyandreev [35.5K]

$x = \frac{1}{2}$ and $y = - \frac{3}{2}$

Step-by-step explanation:

$\frac{2x}{x + y} = \frac{3}{2}$

$= > \frac{x + y}{xy} = \frac{4}{3}$

$= > \frac{1}{x} + \frac{1}{y} = \frac{4}{3}$ ---- Eq. 1

Then,

$\frac{xy}{2x - y} = - \frac{3}{10}$

$= > \frac{2x - y}{xy} = - \frac{10}{3}$

$= > - \frac{1}{x} + \frac{2}{y} = - \frac{10}{3}$ -- Eq. 2

Let

$\frac{1}{x} = u$ and

$\frac{1}{y} = v$ .

Then, from Eq. 1 & 2, we get:

$u + v = \frac{4}{3}$ and

$- u + 2v = - \frac{10}{3}$

$= > 3u + 3v = 4$ and

$- 3u + 6v= - 10$

By adding, we get,

$9v = - 6$

$= > v = \frac{ - 6}{9}$

$= > v = - \frac{2}{3}$

Substituting "y" got above in Eq.1, we get,

$\frac{1}{x} - \frac{2}{3} = \frac{4}{3}$

$= > \frac{1}{x} = \frac{6}{3} = 2$

$= > x = 2$

Hence,

$x = \frac{1}{2}$

$= > y = - \frac{3}{2}$

Urgent help please! Answer any of the questions!

kiruha [24]

#1. x = - (2y) / (1-y)

#2. x = (-4y-3)/(1-y)

I can't really see the other questions, so I only did the first two. Hope this helps!
