Answer:

A. x \leq -16  

B. b > 11

C. c \leq -13

D. x \geq -9

Step-by-step explanation:

<u>Given the following algebraic expression;</u>

A. \frac {3x}{4} \leq 12

We would simplify the equation by multiplying all through by 4;

4 * \frac {-3x}{4} \leq 12 * 4

-3x \leq 48

Divide both sides by -3;

x \leq -16

B. 5b - 28 > 27

Rearranging the equation, we have;

5b > 27 + 28

5b > 55

Divide both sides by 5

b > 11

C. 13c \leq -169

Divide both sides by 13

c \leq -13

D. 3x - 7 \geq 4x + 2

Collecting like terms, we have;

3x - 4x \geq 2 + 7

-x \geq 9

Divide both sides by -1

x \geq -9

The slope is 2.

Step-by-step explanation:

You can see on the intercepts that it goes rise 2 and run over 1 which would basically equal to 2.

Solve as a difference equation.
zhannawk [14.2K]

Solution :

Let y = amount of caffeine at a given time in body.

n = number of hours

So $\frac{dy}{dn}= - \ Y$

$\Rightarrow \frac{dY}{Y}=- 0.01 \ dn

ln Y = -0.01 n + C

At n = 0, Y = 130 mg

ln 130 = -0.01 x 0 + C

C = ln 130

$ \ln \frac{Y}{130} =- 0.01 \ n$

$Y = 130 \ e^{-0.01n}$

When Y = 65

$65 = 130 \ e^{-0.01 n }$

$\frac{65}{130}=e^{-0.01n}$

$\ln \frac{1}{2} = -0.01 \ n$

n = 69.315 hours

At n = 24 hours

$Y = 130 \ e^{-0.01 \times 24}$

Y = 102.26 mg
