Consider the product P(x) = (3x2 - 6x + 2)(7x + 3).What is the numerical coefficient of the x term in P(x)?
Enter only a number for your answer.

Answers

Answer:

-4

Step-by-step explanation:

Notice that the only way to multiply 2 numbers from each of the polynomials and get an x term is to multiply a constant and an x term.

The only ways to do that is to multiply -6x by 3 and 7x by 2.

After you're done multiplying, just combine the 2 like terms:

-18x+14x

=-4x

Therefore, the coefficient of the x term is -4.

Josiah and his friends are going to the movies. Each ticket costs $10, and popcorn is $5 a bag. There is a $3 service fee for the entire purchase. He has $75. If he buys 4 tickets, how many bags of popcorn can he buy? if x=number of tickets and y=number of popcorn which of the following inequalities would you use to answer the problem?A x+y=75
B 10x+5y+3≤75
C 10x+5y≤75
D 10x+5y+3≥75

Answers

Answer:

B.

Step-by-step explanation:

If each ticket costs $10 and each popcorn costs $5, with x = number of tickets and y = number of popcorn and $3 the service we have

10x+5y+3 = total cost.

Now, he has a total of $75 and he buys 4 tickets so

10(4)+5y+3 = 75

40+5y+3 = 75

43+5y=75

5y = 75-43

5y = 32

y = 32/5 = 6.4 ≈ 6 popcorn.

Then, he can buy 6 popcorns. Now, to find the inequality we need to know that if he has $75, the total cost can't exceed $75, that is, the total cost needs to be less or equal to $75.

10x+5y+3 ≤75.

B
Because if x equals the number of tickets the it would be 10 X x. Same with the popcorn. for example: x=5 And y =3. it would be
10(5)+5(3)+3=$68

Answers

Median is a better measure of center than the mean(average)

a) 56,62,68,71,104,507 ⇒ Median is a better measure. Mean is not a better measure because of the outliers.

b) 2,8.5, 9.2, 9.8, 10.1 lb ⇒ Median is a better measure. 

c) Mean is a better measure. No outliers. Data set values are close with each other.

d) Mean is a better measure.

You owe $1,000 on a credit card that has an interest rate of 27.99% and make only the minimum payment of $20 each month. Which answer is correct?A. You will have the card paid off within a year.
B. You will never have the credit card paid off.
C. You will have it paid off within 5 years.
D. You will have the credit card paid off within 10 years.

Answers

Answer: The credit card will paid off within 10 years, therefore the correct option is D.

Explanation:

Let the number of years in which the credit card will aid of be x.

It is given that amount owed on credit card is $1000 with interest rate 27.99%.

So the amount of interest is calculated as,

1000* (27.99)/(100) =\$27.9

The total amount have to pay is,

\$1000+\$279.9=\$1279.9

The minimum payment is $20 each month.

x=(1279.9)/(20)

x=63.995

So, the credit card will paid of in 63.995 months. We know that 1 year =12 months.

(63.995)/(12) =5.33

Therefore, the will paid of in 5.33 years, s we can say that the credit card will paid off within 10 years, therefore the correct option is D.

Final answer:

The correct answer is not listed; it would take significantly longer than 10 years to pay off a $1,000 credit card debt at 27.99% APR by making only $20 minimum payments due to the high interest rate.

Explanation:

When dealing with credit card debt, it is crucial to understand the impact of making only minimum payments, especially when the interest rate is high. In the example provided, a credit card balance of $1,000 with an annual percentage rate (APR) of 27.99% and a minimum payment of $20 per month would take much longer than any of the given options to pay off if one were to only make minimum payments. Calculations using a debt repayment calculator or an amortization formula would show that the option of paying it off within 1, 5, or even 10 years by making minimum payments only is not feasible due to the high-interest costs that add up each month. The correct answer would be similar to the situation in which it takes about 15 years to pay off a $2,000 debt, making minimum payments will eventually lead to a payoff, but with a larger cost in interest over time.
