Can someone pls explain to me how Identify the domain and range of a graph!!, ​

Answers

Answer:

Ok

Step-by-step explanation:

So, the domain is the set of all possible values that can be inputted into the function. Or where is function on the x axis is the function defined. The range is similar but on the y axis. In this case, the function you have there appears to go on to infinity (I assume that is what the arrow means) and so the range would be [-1, -infinity) and domain [1, infinity). Brackets are important here because it shows that the function is still defined at point (1,-1), therefore, I used [ bracket symbol (I again assumed that the shaded in black dot at point (1,-1) means that the function is closed at that point and that when it is not shaded in, it is open). I feel like I didn't explain very well but good luck and hopefully someone does a better job that what I did.

Ron is saving money for college. Each month he deposits 10% of his net income plus

an additional $50 into a savings account. His net income, after taxes have been taken

out, is 80% of his gross income. Find the amount that Ron saves a month when his

gross income is $2400.

Answers

Answer:

$242

Step-by-step explanation:

His Gross income a month is $2400.

Now, we are told that his net income, after taxes have been taken out, is 80% of his gross income.

Thus;

Net income a month = 80% × 2400 = $1920

Now, Each month he deposits 10% of his net income plus an additional $50 into a savings account.

This means amount saved each month is = (10% × 1920) + 50 = 192 + 50 = $242

Suppose m <6= 147º. Find <1 and m<3

Answers

Answer:

∠ 1 = ∠ 3 = 33°

Step-by-step explanation:

∠ 3 and ∠ 6 are same- side interior angles and are supplementary , thus

∠ 3 + ∠ 6 = 180° , that is

∠ 3 + 147° = 180° ( subtract 147° from both sides )

∠ 3 = 33°

∠ 1 and ∠ 3 are vertical angles and congruent, thus

∠ 1 = ∠ 3 = 33°

The American Academy Dermatology says that hair grows about 6 inches per year. How much hair can you expect to grow after 3 years, given that you do not get any haircuts.

Answers

About 18 inches / 1 foot and 6 inches

If hair grows about 6 inches every year, and we want to find out how much will grow in 3 years, we multiply.

6 x 3 = 18 inches

Then we can simplify it because there are 12 inches in a foot

18/12 = 1 6/12

In the state of New Mexico, 85% of the land is above 4,000 feet in elevation.
Which fraction is equivalent to 85%?
A) 4/5
B) 5/8
C) 17/20
D) 1/85

Answers

Answer:

85 % = 17/20

Step-by-step explanation:

It is given that,

85% of the land is above 4,000 feet in elevation.

We need to write a fraction that is equivalent to 85%.

We know that, percent means dividing by 100 i.e.

[tex]85\%=\dfrac{85}{100}[/tex]

We can write 85 as 17×5 and 100 as 20×5

So,

[tex]\dfrac{85}{100}=\dfrac{17\times 5}{20\times 5}[/tex]

5 will cancel out from numerator and the denominator

[tex]\dfrac{85}{100}=\dfrac{17}{20}[/tex]

Hence, the correct option is (c).

Which equation can be used to find T the number of tickets each class needs to sell so that the total amount raised is the same for both classes

Answer:

C.

Step-by-step explanation:

If you know how much each class is selling tickets for and how much they've already raised then you take those two values and set them equal to each other.

2.5t + 350 = 3t + 225

To actually find the number of tickets each class would have to sell you would just solve for t.

In the second table, choose coordinates that don't make the relation a function.

function: (1, 98), (2, 98), (3, 2), (4, -86)not a function: (1, 98), (2, 98), (3, 2), (3, -86)

Step-by-step explanation:

A relation that is a function has unique x-values. A relation that is not a function has at least one x-value that is repeated. The y-values do not need to be unique in either case, except that a repeat of the same (x, y) pair does not disqualify a relation from being a function.

In the table shown above, the non-function has the x-value of 3 repeated with different y-values.
