For how many positive integer values of N will the expression 18/N + 2 be an integer?
Answers
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?
Answers
30,000÷0.07=428,571
If the federal reserve rate is 5% the money supply would be
30,000÷0.05=600,000
The affect
600,000−428,571=171,429
Increase by 171429
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
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
Answers
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.

In March Tom had -£165 in his bank account. In April he had -£156.
In which month did he have the least amount of money in his account?
Answers
Answer:
March.
Step-by-step explanation:
We have been given that in March Tom had -£165 in his bank account. In April he had -£156.
We know that the a biggest negative number has least value as biggest negative numbers lie on the extreme left on the number line.
Since -£165 is more negative than -£156, so -£165 is the least amount.
Therefore, Tom had least amount of money in his account in March.

When writing an equation in exponential form , how can you tell by the number in parentheses if it's exponential growth or exponential decay?
Answers
The multiplier is 100%+4%=104% = 1.04
The growth formula is
y = A₀(1.04)ˣ
Where A₀ is the initial value
One example of a decay is a decrease of 12% per annum
The multiplier is 100% - 12% = 78% = 0.78
The equation for the decay is
y = A₀(0.75)ˣ
The difference between these two equations is that for the growth, we have a multiplier that is bigger than 1, whereas, for the decay, we have a multiplier that is less than 1.
Match the graph with the correct equation.
y – 1 = –4(x + 5)

Part A: Write a sentence to compare the slope of the two functions and show the steps you used to determine the slope of f(x) and g(x).
Part B: Which function has a greater y-intercept? Justify your answer.
Answers
3-(-1)/1-0, which then equals 4/1 which equals 4, and g(x) also has a slope of 4. So, the slopes in both functions are equal.
Part B: g(x) has a a greater y-intercept.
y=mx+b where b is the y-intercept and in the equation g(x)=4x+3, b=3 which makes 3 the y-intercept. Now, for the other function, the y-intercept is when x=0, and when x=0, f(x) (or y) equals -1 and 3>-1 so g(x) has the greater y-intercept.
