Answer:
y = -2x-2
Step-by-step explanation:
y=mx+b
m is the slope, which you already wrote (-2)
b is the initial condition, the value of y when x equals 0.
For (-4,6), we need a value 0 for x, so we add 4, but for each x value added, we add -2 to the y value, so 4 times, 6 - 8 = -2

Final answer:
1 5/8 is equivalent to the decimal 1.625. To find this, one must convert the fraction 5/8 to its decimal form, 0.625, and then add it to the whole number 1.
Explanation:
The decimal equivalent to 1 5/8 is found by converting the fraction 5/8 to a decimal and adding it to the whole number 1. The fraction 5/8 is equivalent to 0.625 when converted to decimal form. Therefore, when you combine 1 with 0.625, the result is 1.625.
To convert 5/8 to decimal, divide 5 by 8, which equals 0.625. This process is similar to using the reciprocal to multiply, as discussed in the context of 1/8 being a '125–like' number. In this case, divide by 8 rather than multiply.
There are 20 more pennies than nickels in a jar. There are 5 time as many pennies as nickels in the jar. How much money is the jar?

5*5+25*1= 50 centsMiguel is playing a game in which a box contains four chips with numbers written on them. Two of the chips have the number 1, one chip has the number 3, and the other chip has the number 5. Miguel must choose two chips, and if both chips have the same number, he wins $2. If the two chips he chooses have different numbers, he loses $1 (–$1).
Let X = the amount of money Miguel will receive or owe. Fill out the missing values in the table. (Hint: The total possible outcomes are six because there are four chips and you are choosing two of them.)

What is Miguel’s expected value from playing the game?
Based on the expected value in the previous step, how much money should Miguel expect to win or lose each time he plays?
What value should be assigned to choosing two chips with the number 1 to make the game fair? Explain your answer using a complete sentence and/or an equation.
Answer:
To check all the events (6), we label the chips. Suppose one chip with 1 is labeled R1 and the other B1 (as if they were red and blue). Now, lets take all combinations; for the first chip, we have 4 choices and for the 2nd chip we have 3 remaining choices. Thus there are 12 combinations. Since we dont care about the order, there are only 6 combinations since for example R1, 3 is the same as 3, R1 for us.
The combinations are: (R1, B1), (R1, 3), (R1, 5), (B1, 3), (B1, 5), (3,5)
We have that in 1 out of the 6 events, Miguel wins 2$ and in five out of the 6 events, he loses one. The expected value of this bet is: 1/6*2+5/6*(-1)=-3/6=-0.5$. In general, the expected value of the bet is the sum of taking the probabilities of the outcome multiplied by the outcome; here, there is a 1/6 probability of getting the same 2 chips and so on. On average, Miguel loses half a dollar every time he plays.

D. (-12, 2), (-9,1),(-6, 0).(-3,-1), (0.-2)
Answer:
C
Step-by-step explanation:
The correct option is C, as the pairs in this option are the inverse of the ordered pairs given in the original function. It's important to remember that in an inverse function, the x and y values of the original pairs are swapped.
Explanation:To answer this question correctly, it's important to understand what an inverse function is. In a function, we have pairs of values where the first value is the input (or x-value) and the second value is the output (or y-value). When we talk about the inverse function, we simply swap these pairs. That is, if (a, b) is in the function, then (b, a) is in the inverse function.
Considering this fact, we can determine the answer by looking for the option in which the y-value in the original pair becomes the x-value and vice versa. Given that, option C is the correct answer: (12,-2), (9, -1), (6,0), (3, 1), (0,2). This is because they are the inverse pairs of the original table of values.

Claude took out a subsidized student loan of $12,775 at a 9.6% APR
compounded monthly, to pay for his last 2 semesters of college. If he will
begin paying off the loan in 15 months, how much will he owe when he
begins making payments?
?????
Answer:
12,775.00, since the government is responsible for the interest on the loan that accrues before Claude starts making payments
Step-by-step explanation:
APEX
Final answer:
To find out how much Claude will owe after 15 months of deferment on his student loan, we use the formula for future value with compound interest, considering the loan amount, annual interest rate, and compounding period. The future value is calculated as $14,389.49, which is the amount he will owe when he starts repayment.
Explanation:
To calculate the amount Claude will owe when he begins making payments on his subsidized student loan, we need to apply the formula for the future value of a loan with compound interest.
The loan has a principal amount of $12,775, an annual interest rate of 9.6% compounded monthly, and no payments will be made for a period of 15 months (the deferment period).
The future value FV of the loan after t periods of compounding at an interest rate of r per period can be calculated by the following formula:
[tex]FV = PV (1 + r)^t[/tex]
Where:
PV is the present value or initial amount of the loan ($12,775)r is the monthly interest rate (APR/12)t is the total number of compounding periods (15 months)First, we convert the APR to a monthly interest rate:
Monthly interest rate = APR / 12 = 9.6% / 12 = 0.8% = 0.008
Now we calculate the future value after 15 months:
FV = $12,775 × (1 + 0.008)¹⁵
FV = $12,775 × (1.008)¹⁵
Using a calculator, we find:
FV ≈ $12,775 × 1.1262 ≈ $14,389.49
Therefore, Claude will owe approximately $14,389.49 when he begins making payments.

a student asks you why it is possible to have an increase of 150% in price, but not a decrease of 150% in price. how would you answer the student?
Answer:
You can increase by 100% and more of the price in something but you can never decrease more than 100% of something.
Step-by-step explanation:
If you have something that costs 8 dollars to begin with then all of the sudden it costs 20 dollars, it increased by 150%. 8 is 100$ of 8, 4 is 50% of 8. 8+4=12. 12+8=20. The price began at 8 then increased by itself plus half of it which is 12.
IF you decrease the price by 150% it'll be -20 dollars. You cant physically have negative amount of money.

Use the model to write the equivalent fraction. The colored pieces show parts of the whole.
Final Answer:
The equivalent fraction for the given model with colored pieces representing parts of the whole is 3/4.
Explanation:
In the provided model, there are three colored pieces out of a total of four. To determine the equivalent fraction, we look at the ratio of the colored pieces to the total number of pieces. Since there are three colored pieces and four pieces in total, the equivalent fraction is 3/4. This fraction represents the relationship between the colored parts and the whole, where the numerator (3) indicates the number of colored pieces, and the denominator (4) represents the total number of pieces in the model.
The process of finding equivalent fractions involves identifying a fraction that represents the same part-to-whole relationship. In this case, we can simplify the fraction by dividing both the numerator and denominator by their greatest common factor. However, in this instance, 3/4 is already in its simplest form, as 3 and 4 do not have a common factor other than 1. Therefore, the equivalent fraction remains 3/4.
Understanding fractions is essential in various mathematical concepts and real-world applications. They represent parts of a whole and are crucial in areas such as geometry, probability, and everyday calculations. In this scenario, the fraction 3/4 precisely captures the proportion of colored pieces in the given model, providing a clear and concise representation of the relationship between the highlighted elements and the entirety of the model.
