What is the slope of a line parallel to the line whose equation is 6x + 5y = -5.
Fully simplify your answer.
➢◇✳︎✧✥---------------------------------------------✥✧✳︎◇⤎
\(Hello\) \(There!\)
We need to find the slope of the line that's parallel to 6x+5y=-5.
It's not hard, I promise! I'm going to take you through a few steps, and we'll find the answer.
Are you ready? Let's start. :)
\(Procedure:\)
➢ First, subtract 6x from both sides:
5y=-5-6x
✦ Switch the order of the terms:
5y=-6x-5
➢ Now, divide both sides by 5:
y=-6/5x-5/5
✦ Which is the same as
\(\bold{y=-\displaystyle\frac{6}{5} x-1}\)
➢ Part of the problem's already solved! :)
Now, parallel lines have the same slope.
✦So the slope of the line parallel to 6x+5y=-5 is also:
◉ \(\bold{-\displaystyle\frac{6}{5}}\) ☑︎
Problem solved! :)
hope it's helpful!wishing you a great day!\(Greetings !\)

-x/2 + 3/2 < 5/2 Solve the inequality. Show your work
Answer:
x > -2
Step-by-step explanation:
\( -\frac{x}{2} + \frac{3}{2} < \frac{5}{2} \)
Subtract ³/2 from each side
\( -\frac{x}{2} + \frac{3}{2} - \frac{3}{2} < \frac{5}{2} - \frac{3}{2} \)
\( -\frac{x}{2} < \frac{5 - 3}{2} \)
\( -\frac{x}{2} < \frac{2}{2} \)
\( -\frac{x}{2} < 1 \)
Multiply both sides by -2 (multiplying both sides by a negative number will change the sign of inequality from < to >)
\( -\frac{x}{2} * -2 < 1 * -2 \)
x > -2

You have a credit card with a balance of $1,367.90 at a 9.5%
APR. You pay $400.00 each month on the due date until the
card is paid off. How many months does it take to pay off the
card, and what is the total amount paid including interest?
Be sure to include in your response:
• the answer to the original question
. the mathematical steps for solving the problem
demonstrating mathematical reasoning
Given statement solution is :- It takes 4 months to pay off the card, and the total amount paid, including interest, is $1600.
To determine the number of months it takes to pay off the credit card and the total amount paid, including interest, we can follow these steps:
Step 1: Calculate the monthly interest rate.
The APR (Annual Percentage Rate) is given as 9.5%. To find the monthly interest rate, we divide this by 12 (the number of months in a year):
Monthly interest rate = 9.5% / 12 = 0.0079167
Step 2: Determine the monthly payment.
The monthly payment is given as $400.
Step 3: Calculate the interest and principal paid each month.
The interest paid each month can be calculated by multiplying the monthly interest rate by the current balance.
Principal paid = Monthly payment - Interest paid
Step 4: Track the remaining balance each month.
Starting with the initial balance of $1,367.90, subtract the principal paid each month to determine the new balance.
Step 5: Repeat Steps 3 and 4 until the balance reaches zero.
Continue calculating the interest and principal paid each month, updating the balance, until the remaining balance becomes zero.
Step 6: Determine the total number of months and the total amount paid.
Count the number of months it takes to reach a balance of zero. Multiply the number of months by the monthly payment ($400) to find the total amount paid.
Let's calculate the number of months and the total amount paid, including interest:
Month 1:
Interest paid = 0.0079167 * $1,367.90 = $10.84
Principal paid = $400 - $10.84 = $389.16
New balance = $1,367.90 - $389.16 = $978.74
Month 2:
Interest paid = 0.0079167 * $978.74 = $7.75
Principal paid = $400 - $7.75 = $392.25
New balance = $978.74 - $392.25 = $586.49
Month 3:
Interest paid = 0.0079167 * $586.49 = $4.64
Principal paid = $400 - $4.64 = $395.36
New balance = $586.49 - $395.36 = $191.13
Month 4:
Interest paid = 0.0079167 * $191.13 = $1.51
Principal paid = $400 - $1.51 = $398.49
New balance = $191.13 - $398.49 = -$207.36 (Paid off)
It takes 4 months to pay off the credit card. Now, let's calculate the total amount paid, including interest:
Total amount paid = 4 * $400 = $1600
Therefore, it takes 4 months to pay off the card, and the total amount paid, including interest, is $1600.

In a lottery, the top cash prize was $642 million, going to three lucky winners. Players pick five different numbers from 1 to 56 and one number from 1 to 49.
Save
A player wins a minimum award of $225 by correctly matching three numbers drawn from the white balls (1 through 56) and matching the number on the gold ball (1 through 49). What is the probability of winning the minimum award?
The probability of winning the minimum award is
Total number of possible outcomes:
Number of ways to choose 3 numbers from 56 (56 choose 3): 56! / (3! * (56 - 3)!) = 22,957
Number of ways to choose 1 number from 49: 49
Total number of possible outcomes = 22,957 * 49 = 1,128,593
Number of favorable outcomes:
Number of ways to choose 1 number from 49: 1
Number of favorable outcomes = 1
Probability of winning the minimum award:
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 1 / 1,128,593 ≈ 0.000000888, or approximately 0.0000888%

Which expression uses the associative property to make it easier to evalute?
Answer:
The correct option is (c).
Step-by-step explanation:
The given expression is :
\(14(\dfrac{3}{2}\times \dfrac{1}{4})\)
We need to use the associative property to make it easier.
The associative property for multiplication is as follows :
\(A\times (B\times C)=(A\times B)\times C\)
We have,
\(A=14, B=\dfrac{3}{2}\ and\ C=\dfrac{1}{4}\)
\(14(\dfrac{3}{2}\times \dfrac{1}{4})=(14\times \dfrac{3}{2})\times \dfrac{1}{4}\)
Hence, the correct option is (c).
Steven and his family ordered a meal the cost 136.50. Steven paid 14% sales tax and left a 20% tip on 136.50. What was the total cost
Answer:
The total cost was $182.91.
Step-by-step explanation:
Tax formula:
tax=tax percentage×amount
Tip formula:
tip=tip percentage×amount
solve
First find the tax. Write 14% as the decimal 0.14 before using it in the equation.
tax
= tax percentage×amount
= 0.14×136.50
= 19.11
The tax was $19.11.
Now find the tip. Write 20% as the decimal 0.20 before using it in the equation.
tip
= tip percentage×amount
= 0.20×136.50
= 27.3
The tip was $27.30.
Finally, find the total cost.
total cost
= cost + tax+tip
= 136.50+19.11+27.30
= 182.91
Answer:
182.91

Michael invests $1,000 in an account that earns a 4.75% annual percentage rate compounded continuously. Peter invests$1,200 in an account that earns a 4.25% annual percentage rate compounded continuously. Which person's account will grow to $1,800 first?
Answer:
Step-by-step explanation:
We can use the formula for continuous compounding to determine how long it will take each account to reach $1,800.
For Michael's account, the formula is:
A = P*e^(rt)
where:
A is the amount in the account after t years
P is the principal
r is the annual interest rate
t is the time in years
Plugging in the values given, we get:
1,800 = 1,000*e^(0.0475t)
Taking the natural logarithm of both sides, we get:
ln(1,800/1,000) = 0.0475t
t = ln(1,800/1,000)/0.0475
t ≈ 8.55 years
So it will take approximately 8.55 years for Michael's account to reach $1,800.
Similarly, for Peter's account, the formula is:
A = P*e^(rt)
where:
A is the amount in the account after t years
P is the principal
r is the annual interest rate
t is the time in years
Plugging in the values given, we get:
1,800 = 1,200*e^(0.0425t)
Taking the natural logarithm of both sides, we get:
ln(1,800/1,200) = 0.0425t
t = ln(1,800/1,200)/0.0425
t ≈ 9.03 years
So it will take approximately 9.03 years for Peter's account to reach $1,800.
Therefore, Michael's account will grow to $1,800 first as it will take less time (8.55 years) compared to Peter's account (9.03 years).

Write the set that represents the set of people surveyed who subscribe to at least one of the two news sources given.
Complete Question
The complete question is shown on the first uploaded image
Answer:
The correct option is d
Step-by-step explanation:
From the question we are told that
The set of people in a certain community who were asked if they subscribe to an information source is U
The set that subscribes to The Daily Informer is D
The set that subscribe to News Magazine is N
Here the universal set is U
Now the word at least here means that the person can subscribe to one or two of the information source , but the person cannot subscribe none of the information source
Now to get the set that represents the set of people surveyed who subscribe to at least one of the two news sources , we need to carry out a union operation on the sets representing the two news source , this can be mathematically represented as
\(L = N \ u \ D\)
So the sets that will contain all the people in the community that subscribe to at least one of the news source is L

A vendor is selling microwavable serving bowls at a listing price of $425 less a 42% trade discount. You order 500 dozen sets of the bowls at the list price of $425, how much money (in $) will be saved with a 42% discount.
Answer:
Therefore, the total amount of money saved with a 42% trade discount on an order of 500 dozen microwavable serving bowls at a list price of $425 per set is $1,071,000.
Step-by-step explanation:
To calculate the amount of money saved with a 42% trade discount, we first need to find the discount amount.
The list price of the microwavable serving bowls is $425 per set. The trade discount is 42%, which means that the vendor is offering a discount of 42/100 x $425 = $178.50 per set.
To find the total savings for an order of 500 dozen sets (1 dozen = 12 sets), we need to multiply the discount per set by the number of sets and then by the number of dozens:
Total savings = Discount per set x Number of sets x Number of dozens
Total savings = $178.50 x 500 x 12
Total savings = $1,071,000

one fifth
5
20
25
Answer:
20
Step-by-step explanation:
The theoretical probability of drawing 2 red marbles from the bag with replacement is one-fifth, which means that the probability of drawing 2 red marbles in any one trial is 1/5 or 0.2.
The number of times Jonah is expected to select 2 red marbles in 100 trials can be predicted using the expected value formula:
Expected value = (Number of trials) x (Probability of success in one trial)
Expected value = 100 x 0.2
Expected value = 20
Therefore, a reasonable prediction of the number of times Jonah will select 2 red marbles in 100 trials is 20. Therefore, the answer is 20.
