Solve the compound inequality: n+1<=-3 or -4n<-8
Answer:
-4n<-8 the answer for this is (n>2)
n+1<=-3 the answer for this is (n<=-4)
The value of n is less than equal to negative 4 and greater than 2. n ≤ –4 and n > 2.
What is inequality?Inequality is defined as an equation that does not contain an equal sign. Inequality is a term that describes a statement's relative size and can be used to compare these two claims.
The inequalities are given below.

A population of rabbits is tripling every week. If the population starts with 5 rabbits, how many rabbits will there be at the end of 7 weeks?
Answer:
10,935 bunnies at the end of 7 weeks
Step-by-step explanation:
5 x 3 = 15
^ x 3 = 45
^ x 3 = 135
^ x 3 = 405
^ x 3 = 1,215
^ x 3 = 3,645
^ x 3 = 10,935

ASAP Analyze the Error: What is the error in the way the calculation of the slope of the two points is set up and/or solved? Please be specific.
Answer/Step-by-step explanation:
Given two points on a line, (-4, 10) and (0, 2), the slope of the line is calculated as follows:
[tex] slope (m) = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Let,
[tex] (-4, 10) = (x_1, y_1) [/tex]
[tex] (0, 2) = (x_2, y_2) [/tex]
Plug in the values
[tex] slope (m) = \frac{2 - 10}{0 - (-4)} [/tex]
[tex] slope (m) = \frac{-8}{4} = -2 [/tex]
Slope = -2
The wrong formula was used. Slope is supposed to be change in y over change in x. Rather the difference of each coordinates was solved and divided by each other, which makes the whole calculation wrong.

Aldrine is buying coffee for his coworkers. He orders small and large coffees. Small coffees
cost $3 and large coffees cost $5. He spent $30 and ordered eight cups of coffee in total.
Write a system of equations that represents the situation
How many of each coffee did he buy? How do you know?
Let small cups = S
Large cups = L
They bought a total of 8 cups, so S + L = 8
Rewrite as S = 8-L (1st equation)
Then you also have
$3S + $5L = $30 (2nd equation)
Replace the S in the second equation with the first equation:
$3(8-L) + $5L = $30
Simplify:
24 - 3L + 5L = 30
Combine like terms:
24+2L = 30
Subtract 24 from both sides:
2L = 6
Divide both sides by 2:
L = 3
They bought 3 large cups
Since they bought a total of 8 cups, that means they bought 5 small cups ( 8-3=5)
Large = 3 cups, Small = 5 cups

Will give brainliest!!! The MTC Theater holds 250 people, and last night’s performance sold out! Students under the age of 16 paid $2.50 per ticket, while everyone else paid $4.00 per ticket. Last night’s show brought in $910.
Write a system to represent the given equations.
How many adult tickets were sold?
How many under the age of 16 tickets sold
Answer:
Student's tickets: 60
Adult's tickets: 190
I think this is right
Step-by-step explanation:
"Let x represent the number of tickets sold to students under the age of 16. Let y represent those over the age of 16.
Equation 1, number of tickets sold:
The total number of tickets sold to students under the age of 16 plus the number of tickets sold to students over 16 must equal 250 (since the theater was sold out). The equation becomes:
x + y = 250
Equation 2, revenue from tickets sold.
The total revenue was $910. The cost of tickets under 16 is $2.50 and the cost of tickets over 16 is $4.00. The equation becomes:
2.50 * x + 4.00 * y = 910.00
The system of equations to solve is:
x + y = 250
2.50 * x + 4.00 * y = 910.00 "

Object A has 50 kg while Object B has 75 kg. They were pushed with the same amount of force. Which will have greater acceleration
Answer:
Object A will have greater acceleration.
Step-by-step explanation:
Given that,
The mass of object A = 50 kg
The mass of object B = 75 kg
They were pushed with the same amount of force.
We know that, the force acting on an object is given by :
F = ma
Here F is same for both mass
[tex]m_1a_1=m_2a_2[/tex]
Mass and acceleration have inverse relation. It means the object whose mass is less will have greater acceleration. Hence, the acceleration is greater for object A.

Solve The Equation
1/7 (63n - 77) = -11 + 9n
A. No Solution
B. n = 0
C. Infinite Solutions
D. n = 11/9
E. n = -11/9
Answer:
C. Infinite Solutions
Step-by-step explanation:
In order to solve this we fist have to simplify the equation so we do the following:
[tex]\frac{1}{7}(63n -77) = -11 + 9n\\\\(\frac{1}{7})(7)(63n - 77) = (7)(-11 + 9n) \\\\63n - 77 = -77 + 63n\\63n - 77 = 63n - 77[/tex]
From here we know that any value of n is the solution of this equation so the answer is option C.

HELP WILL MARK BRAINLIEST PLEASE ANSWER ALL THREE
Step-by-step explanation:
8. ∠COB and ∠AOD are vertical angles or C
9. Vertical angles are equivalent to each other so 4x-16 = 112°
4x - 16 = 112°
4x - 16 + 16 = 112 + 16
4x = 128
4x/4 = 128/4
x= 32° or D
10. ∠AOC is vertical to ∠DOB therefore the 2 angles are congruent
You can do 360 - (112 + 112) = 2AOC
360 - 224 = 2AOC
136 = 2AOC
AOC = 68°or A
OR
You could just do 180 -112
Since ∠AOD and ∠AOC are supplementary angles, they both add up to 180°
We already know the measure of ∠AOD, it's 112°
So all you would need to do is subtract 112 from 180
And you get 68° or A
I REALLY hope this helps!!!

The value of a baseball player's rookie card began to increase once the player retired. When he retired in 2000 his card was worth $4.23 The value has increased by $2.92 each year since then. Express the relationship relating the value of the card y in dollars and the number of years x the player has been in retirement with an equation. Is the relationship between x and y proportional? What was the value of the card in 2010 ?
Answer:
Relationship: [tex]y =2.92x+4.23[/tex]
They are not proportional
The value is $33.43
Step-by-step explanation:
Given:
[tex]x = years[/tex]
[tex]y = amount[/tex]
When he retired, the expression is:
[tex](x_1,y_1) = (0,4.23)[/tex]
and the rate (m) is:
[tex]m = 2.92[/tex]
Solving (a): The relationship between y and x
This can be solved using the following point-slope formula:
[tex]y - y_1=m(x-x_1)[/tex]
Substitute values for x1, y1 and m
[tex]y - 4.23=2.92(x-0)[/tex]
[tex]y - 4.23=2.92(x)[/tex]
Make y the subject
[tex]y =2.92(x)+4.23[/tex]
[tex]y =2.92x+4.23[/tex]
Solving (b): Are they proportional?
No, they are not
A proportional relationship is expressed as:
[tex]y = mx[/tex]
By comparing this to [tex]y =2.92x+4.23[/tex]; they have different format
Solving (c): Value in 2010?
First, we determine the value of x in 2010
2000; x = 0
2001; x = 1
---
--
-
2010; x = 10
Substitute 10 for x in [tex]y =2.92x+4.23[/tex]
[tex]y = 2.92*10+4.23[/tex]
[tex]y = 29.2+4.23[/tex]
[tex]y = 33.43[/tex]
Sarah took the advertising department from her company on a round trip to meet with a potential client. Including Sarah, a total of 10 people took the trip. She was able to purchase coach tickets for $320 and first-class tickets for $960. She used her total budget for airfare for the trip, which was $4480. How many first-class tickets did she buy? How many coach tickets did she buy?
Answer:
she bought 8 coach, 2 first-class
Step-by-step explanation:
let x = number of coach tickets
equation I used: 320x + 960(10 - x) = 4480
320x + 9600 - 960x = 4480
-640x = -5120
x = 8
At a grocery store you can purchase loose lemons at 2 for $0.99. You can also buy a bag of 6 lemons for $2.50. Which is the better buy? Be sure to show the unit cost for each
Answer:
Bag of lemon
Step-by-step explanation:
Given that:
Cost of loose lemon = $0.99 for 2
Cost of bag of lemon = $2.50 for 6
Calculating the cost per 1 for loose and bag of lemon (unit cost) ;
Loose lemon :
$0.99 /2 = $0.495
Bagged lemon :
$2.50 / 6 = $0.4167
Hence, since the unit cost of bagged lemon is lesser than loose lemon, then purchasing a bag of lemon is better

How much vanilla extract will be needed to make 2 frozen cookies? Show your work.
If you only want to make 9 cookies ( 0.75 of a dozen ) how much quick cooking oats do you need?
How many cups of flour would you need to make 3 dozen cookies?
Answer:
2 teaspoons for the two frozen cookies
3/4 a cup for the cooking oats
2 cups for the flour
Step-by-step explanation:
First Question
The recipe makes 18 cookies. Divide the cookies by 9, half of the batch, to get 2. Now all you have to do is devide the amount of vanilla extract by 9, it will give you two teaspoons.
Second Question1 and 1/2 devided by two since you're devidng the recpie by two to get 9 cookies. A cup is four so 3/4 plus 3/4 equals 6/4. Simplified it'd be 1 and 1/2 or 1 and 2/4.
Third QuestionThe recipe already calls for 1 and 1/2 a dozen. All you're doing is multiplying the recipe b two to get 3 dozen cookies. Now focusing our attention to the flour, there is 1 cup for 1 and 1/2. Multiply 1 by 2 since there is already half of the recipe here. 1 and 1/2 + 1 and 1/2 is 3 so there'd be 2 cups. Basically just double the recipe.
