Answer:

{x|x ≥1} /[ 1,∞ )

Step-by-step explanation:

To find the domain, where expression is defined let

√3x-3≥0

3x-3≥0

3x≥3

x≥1

As domain is all the values of x where the expression is defined, hence the domain becomes  [1,∞) !

For this case we must find the domain of the following expression:

\sqrt {3x-3}

The domain will be given by all the values for which the function is defined. For the given expression to be defined, the argument of the root must be positive. That is to say:

3x-3 \geq0\\3x \geq0 + 3\\3x \geq3\\\x \geq \frac {3} {3}\\x \geq1

Thus, the domain will be given by all the numbers greater than or equal to 1.

Answer:

Domain:x \geq1

Lesechka [4]

Answer: 60= $3.00 and 30= $4.00

x=# of $3 tickets

90-x=# of $4 tickets

$3x+$4(90-x)=$300

3x+360-4x=300

-x+360=300

-x=-360+300

-x=-60

x=60 $3 tickets

90-60=30 $4 tickets

Lyrx [107]

The area of a parallelogram can be found in the same way as that of a rectangle, so base x height. To find the base we have to do area ÷ height or 18 1/3 ÷ 3 1/3= 5.5 feet
