Answer:

x = -7

Step-by-step explanation:

Original Equation:

-2(-2x + 3) - x - 1 = -28

Add 1 to both sides.

-2(-2x + 3) - x = -27

Use distributive property

-2 · (-2x) = 4x

-2 · 3 = -6

Your equation should look like this now:

4x - 6 - x = -27

Add 6 to both sides

4x - x = -21

Subtract x from 4x

3x = -21

Divide both sides by 3

x = -7

Hope this helped :)

Investigators conducting a study regarding the effects of water pollution and peptic ulcer disease obtained the following data:

natima [27]

Answer:

Kindly check explanation

Step-by-step explanation:

The prevalence per 1000 among the exposed :

Total number of diseases among those exposed = 60 + 238 = 298

Prevalence per 1000 among the exposed :

(298 / 9000) * 1000 = 33.11

Prevalence per 1000 among the non exposed :

((90 - 60) + (268 - 238)) / 3000

(60 / 3000) * 1000 = 20

Incidence rate per 1000 among the exposed :

238 / 5940 * 1000

0.0400673 * 1000 = 40.07

Incidence rate per 1000 among the unexposed :

((90 - 30) / (3000-30)) * 1000

(60/2970) * 1000 = 20.2

Which is the equation of an asymptote of the hyperbola whose equation is

goldfiish [28.3K]

Answer:

C. y = 3x - 5

Step-by-step explanation:

Given the general equation of a hyperbola:

$\frac{(x-h)^{2} }{a^{2}}-\frac{(y-k)^{2} }{b^{2}}=1$

The equation for the asymptote line is given by:

$y=k+\frac{b}{a} (x-h)$

In your problem, we have

$\frac{(x-2)^{2} }{4}-\frac{(y-1)^{2} }{36}=1$

we have:

h=2,

k=1

a²=4 --> a=2, im just taking the squareroot

b²=36 --> b=6

put it into your equation

$y=k+\frac{b}{a} (x-h)$

$y=1+\frac{6}{2} (x-2)$

y = 1 + 3(x-2)

y = 1 + 3x - 6

y = 3x - 5
