What is the domain of the function on the graph?

Answers

the answer is letter C
Answer:

The domain of the function is:

        All the real numbers.Step-by-step explanation:

Domain--

Domain of a function is the set of all the x- values for which the function is defined.

and the range of the function is the set of all the values which are attained by the function.

From the graph of the function we see that the graph look similar to the graph of a modulus function such that the graph is extending to infinity in both the direction.

Also, the graph is plotted for all the real numbers.

and the range of the function if all the real  numbers which are greater than or equal to -2.

          Hence,the answer is:

           All real numbers.

how do you know on a right triangle which leg is a or b (Pythagorean Theorem)

Answers

The real answer is: it doesn’t matter! a and b are just labels we give to the legs; it doesn’t matter how you pick them, especially since addition is *commutative* (order doesn’t matter). An equality valid way of writing the equation would be:

(leg 1)^2 + (leg 2)^2 = (hypotenuse)^2

But it saves time to just write it as a^2 + b^2 = c^2, where a and b are the lengths of the legs and c is the length of the hypotenuse.

A truck can be rented from Company A for ​$120 a day plus ​$0.50 per mile. Company B charges $30 a day plus ​$0.80 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.

Answers

120 + 0.5x = 30 + 0.8x 

90 = 0.3x

x = 300

The charges of both companies will be same if truck is driven 300 miles per day.

It is required to find the number of miles in a day.

What is equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign. Equation, statement of equality between two expressions consisting of variables and/or numbers.

Given:

Let the truck is driven X miles per day

Charges of company A will be = $120 + $0.50x

Charges of company B will be = $30 + $0.80

Let us find out value of X when charges of both companies are same

Now the following equation should be made

$120 + $0.50x = $30 + $0.80

$120 - $30 = $0.80x - $0.50x

$90 = $0.30x

x = 300 miles.

Therefore, the charges of both companies will be same if truck is driven 300 miles per day.

Which inequality best represents the situation? A pine tree grows at a rate of 1.5 feet per year. James plants a 2-foot tall pine tree in his yard. How many years will it take for the tree to be at least 14 feet tall? A. 2x + 1.5 ≥ 14 B. 2x – 1.5 ≤ 14 C. 1.5x + 2 ≥ 14 D. 1.5x – 2 ≤ 14

Answers

The answer is C. because 1.5 is the height while x is next to it to show the multiplication of years to height

 it grows 1.5 feet per year so multiply that by number of years (x)

1.5x

 it started at 2 feet tall

 so you would have 1.5x +2 ≥14

 Answer is C. 1.5x + 2 ≥ 14

How many solutions does this equation have? 7v = 7v + 10

Answers

7v = 7v + 10

Subtract 7v from both sides.

0 = 10

Since 0 = 10 is a false statement this equation has no solution.

How many solutions does this equation have?
Answer: none.
So your variable is v. Let's solve for v.

7v = 7v + 10. subtract 7v from both sides
0 = 10

NO SOLUTION

As you can see, 0 does not in fact equal 10.

Anytime you get a false equation like this which usually results when the variable disappears like it did here, there is no solution.

when 18 is subtracted from six times a certain number,the result is -42. what is the number?

Answers

Let x be the number.

Then; 

6x-18=-42 (solve for x now) 
6x=-42+18 
6x=-24 
x=-4 

Therefore, this number would be -4. 

Hope I helped :) 
To start off, you want to create an equation. 18 subtracted six times from a certain number (let's use a variable 'x') would look like: 6x - 18.
6x - 18 = -42

Next, isolate the variable by adding 18 to both sides.
6x - 18 = -42
    + 18   + 18
       6x = -24

Lastly, solve for x.
6x/6 = -24/6
x = -4

The marching band organizes 80 students into 6 lines. How many students are in each line and how many students are left over?

Answers

Do do this, we can simply divide 80 by 6.
First, lets find how many times 6 can go into 80.
6 goes into 80 13 times without going over.
Now, we multiply 13x6 and that's 78.
Since there was 80 to begin with, and we ended up with 78, there would be 2 people left over. So:
There are 13 students in each line and 2 left over.

A bag contains 4 red marbles and 6 blue marbles. Brandon selects one marble from the bag. Without replacing the marble he then selects a second marble. What is the probability that he first selects a blue marble and then selects a red marble?

Answers

Answer:D) 4/15

Step-by-step explanation:

6/10•4/9=4/15 mark brainliest please.

The probability that he first selects a blue marble and then selects a red marble is 4/15.

What is Probability?

It is a branch of mathematics that deals with the occurrence of a random event.

Given,

The number of red marbles in bag=4

The number of blue marbles in bag=6

The total number of marbles in bag are 4+6=10

The probability of selecting a blue ball is 6/10

The probability of selecting a red ball without replacement is 4/9

So the probability that he first selects a blue marble and then selects a red marble

6/10×4/9

24/90

4/15

Hence the probability that he first selects a blue marble and then selects a red marble is 4/15.

Eight bricks are laid end to end along the edge of a flower bed. Each brick is 8 1/2 inches long. How long is the row of bricks in feet

Answers

Eight times 8 1/2 inches comes out to 8(8 1/2 inches) = 8(17/2) = 68 inches.

Answer: The length of row of bricks is 68 inches.

Step-by-step explanation:

Since we have given that

Number of bricks = 8

Length of bricks = [tex]8\dfrac{1}{2}=\dfrac{17}{2}[/tex]

So, Length of the row of bricks is given by

Number of bricks × length of brick

[tex]8\times \dfrac{17}{2}\\\\=4\times 17\\\\=68\ inches[/tex]

Hence, the length of row of bricks is 68 inches.

The E. coli bacterium is about 5×10^−7 meters wide. A hair is about 1.7×10^−5 meters wide. Which is wider, the bacterium or the hair?

The bacterium

The same width

The hair

Answers

The hair is wider than the bacterium.

The E. coli bacterium is about 5×10⁻⁷ meters wide, and a hair is about 1.7×10⁻⁵ meters wide.

To compare the widths of the bacterium and the hair, we can convert both measurements to the same unit.

Let's convert the width of the bacterium to micrometers, which is 5×10⁻¹³ micrometers.

The width of the hair is 1.7×10⁻³ micrometers.

Comparing the two measurements, we can see that the hair is wider than the bacterium.
