An absolute value inequality that has a solution set -1<=x<=3 is |x-1| <= 2
What is the solution set for an inequality?The set of values of the variable involved in the inequality for which the considered inequality holds true is called the solution set for that inequality.
We've to find an absolute value inequality that has the solution set
-1 <= x <= 3
1+2 = 3
and 1 - 2 = 3
Therefore, we can rewrite the considered inequality as:
1-2 <= x <1+2
Subtracting 1 from all the sides:
-2 <= x-1 <= 2
This is written as:
|x-1| <= 2 (it is because [tex]|x| \leq a \leftrightarrow-a \leq x \leq a[/tex] )
Thus, an absolute value inequality that has a solution set -1<=x<=3 is |x-1| <= 2

julia and kelsey are both babysitters. julia charges a flat fee of $30 plus $5 per hour. and kelsey charges a flat fee of $10 plus $15 per hour. which system of equations represents the information given? let z represent the number of hours spent babysitting. let y represent the money earned. (answer choices are in the picture)
Answer:
I think it's the 2nd choice. Hopefully I got this correct :)
Step-by-step explanation:
I think you wrote that z will represent the number of hours spent babysitting but I think you meant x.
It's the 2nd choice because $30 is the flat rate for Julia and $10 is the flat rate for Kelsey. Julia has a rate of $5 per hour so that will be the number with the x. And Kelsey has a rate of $15 per hour so that will be the number with the x.
Julia: y = 5x + 30
Kelsey: y = 15x + 10.

The figure is the net for a rectangular prism.
What is the surface area of the rectangular prism represented by the net?
Enter your answer in the box.
Answer:184 cm^2
Step-by-step explanation:
10*6*2=120
6*2*2=24
2*10*2=40
120+40+24=184
Answer:
184 cm²
Step-by-step explanation:
You can find the surface area of this net by finding the area of each rectangle and adding them up.
The top rectangle has dimensions of 10 and 6. You multiply them to get 60. Add in the units and the area of the top rectangle is 60 cm².
The rectangle under the one we just found the area for has the dimensions 10 and 2. Find the area. A = 20 cm².
The two rectangles to the side of the second rectangle have the dimensions of 6 and 2. The area of one is 12 cm². This means the two rectangles added together are 24 cm².
The next rectangle has the same dimensions as the first rectangle we solved. Therefore, the area is the same, which is 60 cm².
The last rectangle has the same dimensions as the second rectangle we solved. Therefore, the area is the same, which is 20 cm².
We will add the numbers altogether to find the surface area.
60 + 20 + 24 + 60 + 20 = 80 + 24 + 80 = 104 + 80 = 184 cm²

For this item, enter the answer in the space provided. A college student earns $ 15, 000 working part-time at a bookstore. The student pays 1/10 of the earnings in taxes, spends 2/5 of the earnings on living expenses, and saves the remainder of the earnings. How much money does the student save?
Answer: 10,500
Step-by-step explanation:
How to calculate tax and earning
Given the following paramiters
Total amount earned by the student = $15000
Assume we have the following parameters
Earning paid off in taxes = $1500
Amount spent on living expenses = $3000
Amount she will have left = 15000 - (1500 + 3000)
Amount she will have left = 15,000 - 4500
Amount she will have left = 10,500
Hence the amount she will have left is $10,500
Answer:
$7,500
Step-by-step explanation:
First, find the amount he pays in taxes:
$15,000 x 0.1 = $1,500
Next, find the amount he pays in living expenses:
$15,000 x 0.4 = $6,000
Add the two amounts together:
$1,500 + $6,000 = $7,500
Subtract the combined amount from the original amount to find how much the student saved:
$15,000 - $7,500 = $7,500
Therefore, the college student saves $7,500.

Using the given information, which statement is true?
The two triangles are not similar because x≠y .
The triangles are similar because they each have an interior angle with a measure 70°.
The two triangles are not similar because the interior angles are congruent but the side lengths are different.
The two triangles are not similar because y = 60 so it is impossible to have three congruent angles.

last week you walked your dog 12.405 miles. this week you walked your dog 15 miles. how many fewer miles did you walk last week than this week?
The dog walked 3 miles less in last week than this week.
What is approximation?An approximation is anything that is similar, but not exactly equal, to something else. A number can be approximated by rounding.
Given that, last week you walked your dog 12.405 miles. this week, you walked your dog 15 miles.
The dog walked in last week approx = 12 miles
The dog walked this week = 15 miles
The fewer miles did he walked = 15-12 = 3
Hence, the dog walked 3 miles less.

Wyatt is gathering box tops for his school. Last year he was able to collect 300 box
tops. Out of 300 box tops, 25 were already expired. He collected 400 box tops this
year. How many box tops will be expired this year if Wyatt can estimate the
number of box tops that will expire this year using the ratio from last year? Round
to the nearest whole number.
Answer:
Solution
Let last year and new year be L(y) and N(y)
Let last year Expired box and new year Expired box be L(E) and N(E)
Here,
L(y)=300 box
L(E)=25 box
N(y)=400 box
N(E)=x
We know,
N(y) / L(y) = N(E) / L(E)
400/300 = x/25
1.333333333 = x/25
x = 1.333333333 * 25
x = 33.333333333
So, the expire box this year is 33.333333333
