If f(x)=x-3, which inequality can be used to find the domain of f(x)?

Mathematics

Scrat [10]2 years ago

Given that,

f(x) = \sqrt{x-3}

To find,

The domain of f(x).

Solution,

We have, f(x) = \sqrt{x-3}

To find domain,

The term under the square root must be positive or null as follows :

x-3\ge 0

Adding 3 both sides

x-3+3\ge 0+3\\\\x\ge 3

So, the domain is x-3>0 .

What is 3/5th of 42,000
Kipish [7]
We set up a proportion: ?/42,000= 3/5

Cross multiply:
5*?= 3*42,000
⇒ ?= 3*42,000/5= 25,200

3/5 of 42,000 is 25,200~

Please help I don't understand this very well<br>*picture*​
Elenna [48]

Answer:

The inequality is 9 less than and equal to 5

The marked area on the line is numbers all below 5 which covers the less than and since it stop directly at 5 it's going to be equal to that as well

I NEED YOUR HELP PLEASE GRADES ARE DUE TODAY AND I DONT KNOW HOW TO DO THIS.​

Answer:

#1 c. -1

#2 b. 1 is less than or equal to x which is less than or equal to three

#3 a. 37.5 is less than or equal to y which is less than or equal to 87.5

#4 b. 3

#5 b. (2, 3, 4, 5, 6)

#6 d. (45, 55, 65, 75, 85)

Step-by-step explanation:

Domain is the x value and y is the range. For #1 the answer is c because you can't go golfing for -1 hours. For #2, the answer is b because they are all the acceptable values for the domain which is represented by x and x is the time spent at the golfing bay. The answer would not be c because you could go to the bay for 2.75 hours it doesn't have to be just 1, 2, 3.  For #3 the concept is similar because the range aka total cost can be all the values in between 37.5 and 87.5. For #4  a reasonable domain value which is number of people is 3 because you can't have 2.5 people and you can't have -4 people and thus all of the above isn't possible leaving three. #5 is b because you can only have those set numbers to represent people. If you chose a that would mean you could have 1.5 people which isn't possible thus only numbers 2, 3, 4, 5, and 6 are possible. For #6 The answer is d because when you plug in numbers 2, 3, 4, 5, 6 into the x value one at a time and solve the equation, those numbers equal t. Just use your basic knowledge to figure these out there isn't much math you just have to know that domain means x and range means y. y is 9/10 always by itself on one side of the equal sign. When in doubt think, can I have a half a person. Think of the real world and apply to math. Goof luck on future problems!

Answer:

- 1 \frac{1}{8} m +  \frac{3}{10}  \\

Step-by-step explanation:

\frac{7}{8} m +  \frac{9}{10}  - 2m -  \frac{3}{5}  \\  \frac{7}{8} m - 2m +  \frac{9}{10}  -  \frac{3}{5}  \\  \frac{7}{8} m -  \frac{2m \times 8}{1 \times 8}  +  \frac{9}{10}  -  \frac{3 \times 2}{5 \times 2}  \\  \frac{7m - 16m}{8}  +  \frac{9 - 6}{10}  \\  -  \frac{9}{8} m +  \frac{3}{10}  \\  - 1 \frac{1}{8} m +  \frac{3}{10}  \\
