The opposite of a number is the opposite sign of it. So, the opposite of a negative number is a positive number:
Opposite of -23 is 23
The sum of the squares of two different numbers is less than or equal to 49. Twice one of the numbers squared is less than the other number. Which system of inequalities represents these criteria?
Possible answers:
x^2 + y^2 ≤ 49 and 2x^2 < y
x^2 + y^2 ≥ 49 and 2x^2 < y
x^2 + y^2 ≤ 49 and x^2 < 2y
x^2 + y^2 ≥ 49 and x^2 < 2y
This system of inequalities represents is x² + y² ≤ 49 and 2x² < y
What is inequality?
Inequality is the defined as mathematical statements that have a minimum of two terms containing variables or numbers is not equal.
Let the numbers x and y,
According to 1st condition,
The sum of the squares of two different numbers is less than or equal to 49 :
x² + y² ≤ 49
According to 2nd condition,
Twice one of the numbers squared is less than the other number :
2x² < y
Hence, this system of inequalities represents is x² + y² ≤ 49 and 2x² < y

Answer:
-1 5/6
Step-by-step explanation:
-2/3 + (-1 1/6)
Look carefully at he number line. Each space between whole numbers is divided into 6. That means that from one mark on the line to the very next one, the distance is 1/6.
Start at -2/3. Since we are dealing with 1/6's, convert -2/3 to 6ths.
-2/3 * 2/2 = -4/6
-2/3 is the same as -4/6, so start at -4/6. Locate 0 on the number line, and move 4 marks to the left. That is -4/6 which is the same as -2/3 and is your starting point.
Now you need to add -1 1/6. Adding a negative number is the same as subtracting a positive number. Adding -1 1/6 is the same as subtracting 1 1/6. That means you need to go left 1 1/6. Since each unit is divided into 6 equal parts, 1 1/6 is 7 marks on the number line. Starting at -4/6, count 7 marks to the left. Where you end up is the answer which is -1 5/6.
Answer: -2/3 + (-1 1/6) = -1 5/6

Six times a number is at least four less than eight times the number. If x represents the number, which will help find
the number?
Answer:
The inequation 6x ≥ 8x - 4 can be used to find the solution.
The solution is x ≤ 2
Step-by-step explanation:
In math, 'at least' represents greater or equal than (which is the inequation simbol ≥)
If x represents the number then six times a number is the multiplication of x by 6, and four less than eight times the number can be written as: 8x -4
6x ≥ 8x - 4
Solving the inequation;
Substracting 6x each side:
0 ≥ 8x - 6x -4
Suming 4 each side
4 ≥ 2x
Dividing by 2 each side
2 ≥ x
2 greater or equal than x is the same as:
x ≤ 2

Which number is not an appropriate result?
A - a shopping receipt that totals $4.90
B - a soccer game where the average score is 4.7
C- a stack of 15.6 watermelons
D- a classroom with 24 students
Answer:
C - a stack of 15.6 watermelons
Step-by-step explanation:
Lets first go through each option:
"A shopping receipt that totals $4.90":
This is an appropriate answer since many items sold are not priced at exact dollars (where there are no cents), so having $4.90 as the total cost after shopping is appropriate.
"A soccer game where the average score is 4.7":
This is also an appropriate result since it is the average score of a soccer game, so finding a decimal is appropriate.
"A stack of 15.6 watermelons":
This is not an appropriate result since it would be strange to say a 'stack' or group of something that is not a whole number.
"A classroom with 24 students":
This is an appropriate result since the number of students is a whole number not a decimal.

Step-by-step explanation:
Answer:
You can’t add both terms because the coefficients are multiplying different variables. It’s like trying to add apples and oranges together. They are two different things. So is this situation, variables b and m are two different things. Therefore you can’t add them together. This means that you can’t simplify the expression any further. This also means that you can’t combine like terms, because the two terms are unalike.

The owner of a used car lot wants to buy many cars at an auction as he can while not spending more than $20000. If he expects the average price to be $4000, how many would he expect to be able to buy?
Answer:
5
Step-by-step explanation:
Given that:
Total maximum amount that the owner wishes to spend = $20000
Average price of each car = $4000
To find:
How many cars that the owner can expect to buy?
Solution:
Total number of cars that the owner can expect to buy can be found by dividing the total money available with the owner with the average price of each car.
i.e.
[tex]\text{Number of cars expected to be bought} = \dfrac{\text{Total money available with the owner}}{\text{Average Price of car}}[/tex]
We have the following values as given in the question statement:
Total money available = $20000
Average price of car = $4000
Therefore, the answer is:
[tex]\text{Number of cars expected to be bought} = \dfrac{20000}{4000} = \bold{5}[/tex]
The owner can expect to buy 5 number of cars.

how do you solve graphs and make an equation from a line on a graph?
Always start on the y-axis.
rise/run
First things first, you have to know your positives, negatives, zeros, and undefined.
To make an equation from the graph you have to know your formula.
y=mx+b
You do the rise first. The rise on the graph is 3. The run is 2. So, that'll make it 3/2. m=slope.
b=y-axis. b=1.
y=3/2x+1 (Example from the image)

3. use the diagram shown to calculate m
Answer: 131
Step-by-step explanation:
The angle A inside the triangle is
180-162 = 18 degrees
The measure of angle N inside the triangle is
180 - 149 = 31 degrees
Now, since we have the inside angles we can find ang P
Inside Ang A + Inside Ang N + Ang P = 180
18 + 31 + P = 180
49 + P = 180
P = 180 - 49
P = 131 degrees

12 in.
18 in.
Answer:
x = 6[tex]\sqrt{5}[/tex]
Step-by-step explanation:
Using Pythagoras' identity in the right triangle.
The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is
x² + 12² = 18²
x² + 144 = 324 ( subtract 144 from both sides )
x² = 180 ( take the square root of both sides )
x = [tex]\sqrt{180}[/tex]
= [tex]\sqrt{36(5)}[/tex]
= [tex]\sqrt{36}[/tex] × [tex]\sqrt{5}[/tex]
= 6[tex]\sqrt{5}[/tex] ← exact value
A fruit stall sells three kinds of fruits - apples, oranges and pears. At the end of the day, they amount of money earned from selling apples and oranges is $372, while the amount of money earned from selling apples and pears is $480. The ratio of the money earned from oranges and pears is 1 : 4. How much money did the fruit stall earn from the apples?
The fruit stall earns 96 dollars from the apples.
How to find how much money the fruit stall earn from the apples?The fruit stall sells three kinds of fruits which are apples, oranges and pears.
Therefore,
The amount of money earned from selling apples and oranges is $372.
The amount of money earned from selling apples and pears is $480.
The ratio of the money earned from oranges and pears is 1 : 4
Therefore,
let
x = amount earned on apples
y = amount earned on oranges
z = amount earned on pears
Therefore,
x + y = 372
x + z = 480
The ratio of the money earned from oranges and pears is 1 : 4. Hence,
x : z
x : 4x
where
z = 4x
Therefore,
x + 4x = 480
5x = 480
x = 480 / 5
x = 96 dollars
Therefore, the fruit stall earns 96 dollars from the apples.
