Answer:
r ≤ -5 and r ≥ 1
Step-by-step explanation:
The solution has two parts:
1) that derived from | 2 +r | ≥ 3 when (2 + r) is already positive. Then:
2 + r ≥ 3, or r ≥ 1
and
that derived from | 2 +r | ≥ 3 when (2 + r) is negative. If (2 + r) is negative, then
|(2 + r)| = -(2 + r) = -2 -r, which is ≥ 3. Therefore, -2 -r ≥ 3, or -r ≥ 5. To solve this for r, divide both sides by -1 and reverse the direction of the inequality sign: r ≤ -5

Answer:
92
Step-by-step explanation:
Start with the first sentence. 7 crates of 12 eggs each and you need to find out how many eggs that is; that's just 12 + 12 + 12 + 12 + 12 + 12 + 12, or 12 * 7, which equals 84.
Real question is: how many do they have now? Well, if they had 8 eggs at first and they just bought 84 more, then the answer is just 8 plus the 84 that they just bought, which is 92.
Please mark as Brainliest! :)
Answer:
Your correct answer is that they now have 76 eggs left.
Step-by-step :
So, to start off, they had 7 boxes with each box with 12 eggs. So multiply 7 by 12.
7 x 12 = 84
Now, they ate 8 eggs.
84 - 8 = 76 eggs

The poetry club had its first bake sale and they made 79.35 dollars. The club members are planning to have 4 more bake sales. Leslie said if we make the same amount at each bake sale we will earn 3,976.50 dollars. Peggy said no way we will earn 396.75 after bake sales. Use estimation to help Peggy explain why Leslie reasoning is incorrect.
Answer:
Peggy is correct, their total bakes sale = $396.75
Step-by-step explanation:
Using estimation to help Peggy explain why Leslie reasoning is incorrect.
From the question we can see that:
First bake sale they made = $79.35
4 more bake sales making the same amount = 4 × $79.35
The total amount they would make from the bake sales =
$79.35 + (4 × $79.35)
= $396.75
Peggy was right. Leslie's reasoning was incorrect.

Step-by-step explanation:
Please help! For each of the following relations, identify whether it’s a function or not and why, then state the domain and range.
Answer:
The first one is a function, the second one is a function, and the third one is not a function.
Domain for the first one, just list the x values. Same for range.
Domain and range for the second one are both all real numbers.
For the last one, solve the quadratic, and find the vertex. The range will be all numbers greater than the y on the vertex, while the domain is all real numbers.
Step-by-step explanation:
An easy way to tell if something is a function or not is to check that each input (or x-value) has a different output (or y-value.) The first one is not a function because in the table, we see that 1 gives an output of 9, but later on you see 1 also gives an output of 20.
If you're ever given a graph and asked this question, do the vertical pencil test. Start at the left of the graph, and slide your pencil over the graph (vertically) and if your pencil ever hits more than one point at a time, it's not a function. Hope this helped!

320÷b∙20 and 320÷(b∙20) for b=4
Answer:
First one equals 16, second equals 4
Step-by-step explanation:
b*20=20b
320/20=16
Second
320/(b*20)
Replace b with 4 so it would be 320/(4*20)
4*20=80, 320/80=4
Simplify 2(x+3)-2(x-6)
Answer:
18
Step-by-step explanation:
=(2)(x)+(2)(3)+(−2)(x)+(−2)(−6)
=2x+6+−2x+12
Combine Like Terms:
=2x+6+−2x+12
=(2x+−2x)+(6+12)
Answer:
2 (x+3) -2 (x-6) =18
Step-by-step explanation:
2 (x+3)= 2x+6
=2x+6-2 (x-6)
-2 (x-6)= -2x+12
=2x+6-2x+12
=2x-2x+6+12
6+12
=18

0.1111111111
Answer:
There’s like this little slach on the top of the number so that’s it a slach on top of the number that is like 11111111111
Step-by-step explanation:
Answer:
0.1111111111=
1111111111
10000000000
Step-By-Step:
Convert the decimal into a fraction by putting the decimal over 1 in fraction format
0.1111111111= 0.1111111111 /1
Multiply the numerator and denominator by 10 to eliminate decimal places
0.1111111111 × 10 /1 × 10 = 1.111111111 /10

solve the compound inequality 6b < 36 or 2b + 12 > 6
Answer:
6b < 36
6b = 36
divide both sides by 6
6b ÷ 6 = 36 ÷ 6
b = 6

3(4x-7)=27
What does x =?
Please help asap im timed!!!
Answer:
x = 4
Step-by-step explanation:
3 x ( 4x -7 ) = 27
3 x 4x = 12x
3 x -7 = -21
12x -21 = 27
12x -21 + 21 = 27 + 21
12x = 48
12x/12 = 48/12
x = 4

Write the sentence as an inequality.
The sum of a number y and 9 is at least -1.
y +9 >= -1
Sum of a number(y) and 9. Is greater than or equal to negative one. Sum means add, so add y, and 9. It has to be atleast negative one, so greater than (0,1,2,3...), or equal to(-1).
Hope this helps, if you have more questions, feel free to ask.
The sum of a number y and 9 is at least -1 as an inequality is y + 9 ≥ 1.
What is an inequality?In mathematics, "inequality" refers to a relationship between two expressions or values that are not equal to each other. To solve the inequality, you may multiply or divide each side by the same positive number, add the same amount to each side, take the same amount away from each side, and more. You must flip the inequality sign if you multiply or divide either side by a negative number.
Given:
An expression,
The sum of a number y and 9 is at least -1.
To find the number in the numerator form,
The sum of y and 9,
y + 9
And the value is at least -1.
So,
y + 9 ≥ 1
Therefore, the inequality is y + 9 ≥ 1

On her last science test, Mariah missed four questions. For those questions, she received a total of -20 points. On the retake, Mariah missed a quarter of the number of questions that she missed the first time. If the tests were scored the same way, how many points did she receive for missing questions on the retake?
-5
-10
-80
-16
Answer:
5
Step-by-step explanation:
in the beginning, she missed 4 questions and received -20 points. it means that each question missed is equal to -5 points.
So, finally, when she missed 1/4 of the four questions, it means that she missed only one question. So, she only received -5 points
