a. all real numbers
b. all real numbers greater than or equal to - 2
c. all real numbers greater than or equal to - 5
d. all real numbers greater than or equal to 0
Answer:
Option a is correct.
Step-by-step explanation:
The given graph is of the function f(x)=|x|-2
Domain are the values that x will take in the given function x can take all the values whether fraction, integer the function will always be defined.
Hence, the domain of the function is all real numbers.
Therefore, Option a is correct.
Answer: Domain are all real number [a].
Step-by-step explanation:
Given : graph .
To find : what is the domain of the function on the graph.
Solution : We have given that a graph of function f(x) : |x| - 2.
Domain : The domain of a function is the set of its possible inputs,that is the set of input values where for which the function is defined.
Therefore, the domain are all real number [a].

d. {(−6,4),(−3,−1),(0,5),(1,−1),(2,3)}
Answer:
The answer is the B)
Step-by-step explanation:
By the definition, in a function, a value in the first set of numbers only have a value in the second set of numbers, so for every pair of numbers, we have to review if the first number for this pair only appears one time in all the function.
All the set ot values agrees with this definition except the B, because the third and fourth pair have the same first value (3)

For how many positive integer values of N will the expression 18/N + 2 be an integer?
N can have 6 different positive integer values.
What is an Expression?An expression is a mathematical statement which consists of variables, constants and mathematical operators.
The expression is :
18/N +2
An integer is a whole number that includes all positive numbers, negative numbers and zero.
An integer cannot be a fraction.
The value of N has to be determined for the expression such that, the value of the expression is a positive integer.
For the expression to be positive integer, the 18/N should be an integer value, so the number N should completely divide 18.
The factors of 18 is 1,2,3,6,9,18.
If N is any value among these, it will divide 18 to give a integer and the value of the expression will be a positive integer value.

If the federal reserve decreases the reserve rate from 7% to 5%, how does this affect the amount of money that would result because of fractional-reserve banking from an initial deposit into a bank of $30,000?
Answer:
The total affect of the decrease in the interest rate = $29400
Step-by-step explanation:
The initial amount of money which has been deposited into the account = $30000
The rate at which the initial money was deposited = 7%
But it is given that the federal reserve decreases the reserve rate from 7% to 5%
Now, we need to find the affect of this decrease on the deposited money
The rate of change in the interest rate = 7 - 5 = 2%
So, The affect of this decrease = 2% of 30000
= $600
So, The money becomes = 30000 - 600
Therefore, The total affect of the decrease in the interest rate = $29400

If the probability of an event is 2/7, what must be the probability of its complement?
Answer:
[tex]\frac{5}{7}[/tex]
Step-by-step explanation:
Let
x------->the probability of its complement
we know that
The Complement Rule states that the sum of the probabilities of an event and its complement must equal [tex]1[/tex]
so
in this problem
[tex]\frac{2}{7}+x=1[/tex]
solve for x
Adds [tex]-\frac{2}{7}[/tex] both sides
[tex]x=1-\frac{2}{7}[/tex]
[tex]x=\frac{5}{7}[/tex]
The probability of its complement is 5/7

Marie worked 2 weeks during her college she earned $280 the first week and 245 the second week. If 1/2 of her total earnings went to taxes and 1/4 went to college tuition how much money did she have left
Marie's total earnings for the two weeks were $525. She paid $262.5 to taxes and $131.25 to college tuition, leaving her with a balance of $131.25.
Explanation:To find out the amount left, we need to first calculate Marie's total earnings for the two weeks by adding what she earned each week. $280 for the first week plus $245 for the second week gives her a total earnings of $525.
Marie gave half of her earnings to taxes, which is 0.5 * $525 = $262.5. After that, she spent one-fourth of her earnings on college tuition, which equals 0.25 * $525 = $131.25. Summing up both amounts, we find that she spent $262.5 + $131.25 = $393.75 on taxes and tuition.
To find out the amount Marie has left, we subtract the total expenses from her total earnings. Thus, $525 - $393.75 = $131.25 is the total amount she has left after paying her taxes and tuition.

After calculating her total earnings, subtracting the amounts for taxes and tuition, Marie had $131.25 left. Her total earnings were $525. 1/2 went to taxes, and 1/4 went to tuition.
First, find her total earnings for the two weeks:
Total Earnings = $280 + $245 = $525
Next, calculate how much went to taxes. Since 1/2 of her total earnings went to taxes:
Taxes = 1/2 x $525 = $262.50
Then, calculate how much went to college tuition. Since 1/4 of her total earnings went to tuition:
College Tuition = 1/4 x $525 = $131.25
Finally, subtract the amounts for taxes and tuition from her total earnings to find out how much money she had left:
Money Left = $525 - $262.50 - $131.25 = $131.25
Marie had $131.25 left after paying taxes and college tuition.
