Explain the difference between solving an and<br> inequality and an or inequality.
adell [148]

Answer:

An <u>and inequality</u> contains compound restrictions, i.e., x must be less that 4 and greater than 1, while an <u>or inequality</u> contains multiple sets of separate restrictions, in which, only one must be fulfilled, i.e., x is greater than 5 or less than -3.

Hope it helps :)

How do you do <br><br>f(x)=12x+3 2units left<br>g(x)=<br><br><br>please help I'm confused ​
Mkey [24]

Answer:

g(x) = 12x + 27

Step-by-step explanation:

Take a point in the f(x).

f(0) = 12(0) + 3

f(0) = 3

A point on f(x) is (0,3).

Move the point 2 units left. It will make the x-coordinate decrease by 2.

0 - 2 = -2

A point on g(x) is (-2,3).

Substitute the point and the same slope into the equation of a line. The slope did not change.

y = mx + b

3 = 12(-2) + b

3 = -24 + b

b = 3 + 24

b = 27

Rewrite g(x) using b = 27 and the same slope, m = 12.

g(x) = 12x + 27

The value of a car after t years can be found using the formula V = C(1 - r)t, where V is the current value of the car, C is the
Stells [14]
The given formula is
V = C(1-r)^{t}

Therefore
(1-r)^{t} =  \frac{V}{C} \\\\ 1-r = ( \frac{V}{C} )^{1/t} \\\\ r = 1 - ( \frac{V}{C} )^{1/t}

Given:
C = $25,000
V = $12,000
t = 4.5 years

C/V = 0.48
1/t = 0.2222
Therefore
r = 1 - 0.48^{0.2222} = 0.1505 = 15.05\%

Answer: 15% (nearest integer)
