Which values of k are solutions to the inequality |-k-2|<18? Check all that apply
-40
Answers
Answer:
any number except -20
Step-by-step explanation:
\(|-k-2|<18\)
\(-k-2<18\) \(-k-2>18\)
\(-k<18+2\) \(-k>18+2\)
\(-k<20\) \(-k>20\)
Multiply by -1 to make the k positive. This will alter all the terms which means 20 will become negative. NOTE: When multiplying or dividing by negative numbers, the inequaliy sign flips.
\(k>-20\) \(k<-20\)
k must be either greater than -20 but not including it or fewer than -20 but not including it; therefore, any number between negative infinity and -21 and -19 and postive infinity

The distance between the elementary school and the middle school is 4 miles. On the map, the two locations are One-half inch apart. What is the scale of the map?
1 inch = 8 miles
1 inch = StartFraction 1 over 8 EndFraction mile
One-half inch = 1 mile
4 inches = 1 mile

Austen has 6 sets of 10 baseball cards. Tim has 3 sets of 10 baseball cards. How many baseball cards do they have in all?
Answers
Answer:
90
Step-by-step explanation:
6 x 10 = 60
3 x 10 =30
60 + 30 = 90
6 sets of 10 cards = 60
3 sets of 10 cards = 30
60+30=90
a committee consisting of 4 faculty members and 5 students is to be formed. every committee position has the same duties and voting rights. there are 7 faculty members and 13 students eligible to serve on the committee. in how many ways can the committee be formed?
Answers
and
C(13, 5) = 13! / (5!(13-5)!) = (13 * 12 * 11 * 10 * 9) / (5 * 4 * 3 * 2 * 1) = 1287
Multiply these two combinations since the faculty members and students are selected independently:
Total number of ways to form the committee = C(7, 4) * C(13, 5) = 35 * 1287 = 45,045
Therefore, there are 45,045 ways to form the committee consisting of 4 faculty members and 5 students.
For faculty members:
There are 7 eligible faculty members, and we need to select 4 of them for the committee. This can be done using the combination formula:
C(7, 4) = 7! / (4!(7 - 4)!) = 35.
So, there are 35 ways to select 4 faculty members from the 7 eligible ones.
For students:
There are 13 eligible students, and we need to select 5 of them for the committee. Using the combination formula again:
C(13, 5) = 13! / (5!(13 - 5)!) = 1287.
Therefore, there are 1287 ways to select 5 students from the 13 eligible ones.
To form the committee, we multiply the number of ways to select faculty members by the number of ways to select students:
35 * 1287 = 44,895.
Hence, there are 44,895 ways to form the committee consisting of 4 faculty members and 5 students from the eligible candidates.

Becky takes out a loan for $5,000. She plans to repay the loan in 8 years. The interest rate is 7.3% compounded annually. How much will she have to pay in interest?
Answers
(0.073 x 5,000) x 8
$2920 is our total interest :)
Answer:
$3785.53
Step-by-step explanation:
You want the interest amount due at the end of 8 years on a $5000 loan at 7.3% compounded annually.
Future valueThe amount due is multiplied by (1 +0.073) each year. After 8 years, the amount due will be ...
5000(1.073^8) ≈ 8785.53
Of that, 5000 is the principal amount, so the remainder is interest.
interest = $8785.53 -5000
interest = $3785.53
Becky will have to pay $3785.53 in interest.

Answer:
reflected across the y-axis, vertical compression by 1/2, shifted 4 to the left, shifted 1 down
Step-by-step explanation:
the negative sign indicates a reflection across the y-axis
the \(\frac{1}{2}\) outside of the parentheses indicates a vertical compression because it is being multiplied and 0 < \(\frac{1}{2}\) < 1
the 4 within the parentheses indicates a shift to the left because it is being added
the 1 outside of the parentheses indicates a shift down because it is being subtracted
good luck, hope this helped!

Which expression is equivalent to -1/3 ( 6x + 15 ) - 3?
a) -2x + 12
b) -2x + 2
c) -2x - 2
d) -2x - 8
Answers
The correct answer is (D) -2x - 8.
To simplify the expression -1/3 ( 6x + 15 ) - 3, we can first apply the distributive property to the term in parentheses:
-1/3 ( 6x + 15 ) - 3 = -1/3 * 6x - 1/3 * 15 - 3
Then we can simplify using the properties of multiplication and division:
-1/3 * 6x - 1/3 * 15 - 3 = -2x - 5 - 3
Finally, we can combine like terms:
-2x - 5 - 3 = -2x - 8
The correct answer is therefore (D) -2x - 8.✅
The sum of digits in a 2 digit number is 14. If you double the reversed number and add the result to the original number, the sum would be 222. Find the original number.
PLS HELP ASAP!!!!!!!
Answers
Answer:
86
Step-by-step explanation:
To figure this equation out I used a guess and check strategy. I looked at all combinations of digits that gave us a sum of 14. When I got to 86, and reversed the digits, I ended up getting 136. When I added 136 to 86 it was 222. We started with seven and seven, and then looked at eight and six and a six and eight. Eight in six was that right combination!
Hope this helps!!
Please tell me if I am incorrect I enjoy learning from my mistakes.
Answer: The answer is 86
Step-by-step explanation: If you double the reversed number (68) you would get 136 then add 86 to that orignal sum and you get 222 voila. How i got the number was I did guess and check.

Since he drank 5/8 of it. The coffee left is now 1-(5/8)
But since the question has asked to give the equation in addition format. Put a plus sign in between the two.
Therefore,
1 + (-5/8)
Solve it,
= 1-(5/8)
= (8-5)/8
= 3/8
Hence the equation is:
1 + (-5/8) = 3/8.
Answer: Therefore,
1 + (-5/8)
Solve it,

The scatter plot shows the resale value of the same make and model car and the age of the car in years. Predict the price you would pay if you purchase one of these cars that is 9.5 years old.
Answers
Answer: $4000
Step-by-step explanation:
In the age of cars you go 9.5 and then go up till you reach a part of the line. In that, you can see that 9.5 goes up and reaches the line at $4000.
The predicted price you would pay if you purchase one of these cars that is 9.5 years old is 4000.
What is a scatter plot?A scatter plot is a graphical representation of bivariate data that uses dots to represent values for two different variables.
The data for each observation is represented by the position of the dot on the x-axis and y-axis.
The x-axis represents one variable and the y-axis represents the other variable.
Scatter plots are commonly used to observe relationships between variables, such as correlations or trends, and to identify outliers or patterns in the data.
We have,
To predict the price you would pay for a car that is 9.5 years old, you need to look at the scatter plot and find the point that corresponds to an age of 9.5 years.
Once you have identified that point, draw a vertical line from that point to the line of best fit (or draw the line of best fit if it's not already on the plot).
Next, draw a horizontal line from the point where the vertical line intersects the line of best fit to the y-axis.
This will give you an estimated price for a car that is 9.5 years old based on the data in the scatter plot.
Now,
We see that,
At 9.5 years, the vertical line and the horizontal line correspond to a resale value of 4000.
Thus,
The predicted price you would pay if you purchase one of these cars that is 9.5 years old is 4000.
