For #10
x=2 w(x)= 5
x=0 w(x)=-9
x=1 w(x)=-1
x=4 w(x)=7
To get these answers, you must use the p(x) table. When x=2, p(x)=6. So you would substitute p(x) for 6 and solve. That would be what you would do for the rest of teh problems.
For #12, the answer would be 5x^2+15x+5

what algorithm (rule) will produce the correct result for the sum "a+b" where a and b each represent any rational number.
Answers
Answer:
To find the sum of a + b where a and b are rational number.
1. when a and b are natural numbers
just add them . for example a =3, b=8
then ,a + b = 11
2. When a and b are whole numbers,
simply add them . for example a= 0, b=8
a+ b = 0 + 8= 8
3. When a and b are integers
for example, a =-1 b=8,
a+ b= -1+ 8 =7,
a=-2, b= -8
a+ b= -2-8=-10
a= -6 , b=2
a+ b= -6 + 2= -4
a= 8, b= -2
a+ b= 8 +(-2) =6
I have written this because Rational number = [Integers{Whole number(Natural number)}]
now when a= Any fraction=[tex]\frac{p}{q}[/tex] and b = Any fraction=[tex]\frac{u}{v}[/tex]
now ,

solve for x: 27=17+2x
Answers
Hello!
Here's how to solve for x.
27=17+2x
Our first step is to subtract 17 from both sides, leaving us with
27-17=17(-17)+2x --- > 10=2x
We then divide both sides by 2 to isolate x!
10/2=2x/2
10 divided by 2 gives us 5 meaning that x=5
[tex]x = 5[/tex]
move variable to left side and change its sign
[tex]27 = 17 + 2x[/tex]
to
(you also move the constant to the right and change its sign)
[tex] - 2x = 17 - 27[/tex]
and then calculate the operation in this case you find the difference
[tex] - 2x= 17 - 27 = - 10 \\ - 2x = - 10[/tex]
you then divide both sides of the equation by -2 since the inverse operation of multiplying is division
[tex]x = 5[/tex]

Choose the number below that represents the digit in the hundreds place of the number 1098. A)8 b)0 c)1 d)9
Answers
The number in the hundreds place is 0
Answer:
B) 0
Step-by-step explanation:
The number that represents the digit in the hundreds place of the number 1098 is 0. Since we know that a hundred (100) has two zeros, this means we will count 2 values starting from the back of the given number (1098). The value before the last number counted will represent the digits in the hundred place. The two values counted from the back are 8 and 9. The value preceding 9 is 0, thereby making 0 to represent the digit in the hundred place.

7t=x,for t .what is the formula
Answers
The formula for t would be x/7.
In order to find this, we simply follow the order of operations to solve for t.
7t = x ----> Divide both sides by 7
t = x/7
To solve the equation 7t = x for t, divide both sides of the equation by 7. This will give you the formula t = x/7.
Explanation:The provided equation in the question is 7t = x. If you're looking to solve for t, we want to isolate t on one side of the equation. In order to do this we have to remove the 7 multiplied by t. To do this, we can divide both sides of the equation by 7. This leads us to the formula t = x/7. Thus removing any variable or value attached to t, we can make t the subject and derive its value

Which addition property is being illustrated below? (Type commutative or associative)
(6 + 7) + 1 = 6 + (7 + 1)
Answers
The associative property
The equation (6 + 7) + 1 = 6 + (7 + 1) demonstrates the associative property of addition, indicating that grouping does not affect the sum of numbers being added.
The addition property being illustrated by the equation (6 + 7) + 1 = 6 + (7 + 1) is the associative property of addition. This property states that when three or more numbers are added, the grouping of the numbers does not change the sum.
In other words, no matter how you group the numbers (which ones you add first), the total is always the same. The equation given shows that whether you add 6 and 7 first, and then add 1, or you add 7 and 1 first, and then add it to 6, the result is the same.
How many solutions does this system of equations have? -x+2y=6 -x+2y=0 A. none B. exactly one C. exactly two D. infinitely many
Answers
i think the answer is going to be d
The system of equations has no solutions because the equations represent the same line and lines are parallel. Therefore, option a is the correct answer.
Let's analyze the system of equations:
−x+2y=6
−x+2y=0
Both equations have the same coefficients for x and y, which means they represent parallel lines.
However, they also have different constants on the right-hand side (6 and 0).
The system of equations is inconsistent because parallel lines with different y-intercepts do not intersect.
Therefore, there are no solutions.
The correct answer is: A. None

You have to be awfully careful with this inequality. If can cause you all kinds of grief.
The easiest way to do this is to begin by dividing by - 1. What that does is turn the inequality

The rule is when you divide by a negative, that turns the < sign to > or the other way around ie > to <. You could actually show that happening.
Start with your given

-(x / 2) + 1 < - 1 + 1 The 1 and - 1 cancel on the right.
-(x/2) + 1 < 0 Add x/2 to both sides
-(x/2) + x/2 + 1 < x/2 Add the like terms on the left.

Mason is skiing with friends he starts at an elevation of 420 feet he descends 600 feet down the mountain into a valley what is his elevation when he stops
Answers
420-600=-180 Hope this helps
Mason's ending elevation after descending 600 feet from a starting elevation of 420 feet is -180 feet, meaning he is below sea level.
To solve for Mason's elevation after his descent, we need to subtract the distance he traveled downward (600 feet) from his starting elevation (420 feet). We can represent this mathematically as:
Elevation after descent = Starting elevation - Descent
Elevation after descent = 420 feet - 600 feet
Elevation after descent = -180 feet
Therefore, when Mason stops, he is at an elevation of -180 feet. This means he is 180 feet below sea level, assuming the initial elevation is measured from sea level.

C. Juan: 4 1/6 ; Antonio: 3 2/3
D. Juan: 25/6 ; Antonio: 11/3

Option D is correct.
Step-by-step explanation:
Given:
Distance Juan runs around a football field = [tex]4\frac{1}{6}\:times[/tex]
Distance Antonio runs around a football field = [tex]3\frac{2}{3}\:times[/tex]
We need to find the distance they run in improper fraction.
We are given Distance in Mixed fraction. So we convert the distance in improper fraction.
Distance Juan runs around a football field = [tex]4\frac{1}{6}=\frac{4\times6+1}{6}=\frac{25}{6}[/tex]
Distance Antonio runs around a football field = [tex]3\frac{2}{3}=\frac{3\times3+2}{3}=\frac{11}{3}[/tex]
Therefore, Option D is correct.
How many baseballs would fit into a box that has the dimensions (3*5)*2
Answers
3*5= 15

30 baseballs
To find out how many baseballs fit in a box with given dimensions, calculate the volume of the box and the volume of the baseball. Divide the total volume of the box by the volume of a baseball for a basic estimation, but remember this doesn't account for packing efficiency or spaces between balls.
Explanation:The question asks how many baseballs would fit into a box with dimensions 3x5x2 cubic units. To solve this, one should first calculate the volume of the box and then divide it by the volume of a baseball.
First, the volume of the box is calculated by multiplying the dimensions: 3*5*2 = 30 cubic units.
For an idealized spherical baseball, the diameter is about 3 inches, giving it a radius of 1.5 inches. The volume of a sphere is given by the formula (4/3)πr³. Using this formula and converting the inches to the same units as the box dimensions, we calculate the volume of a baseball.
Then, we divide the total volume of the box by the volume of a single baseball to determine how many baseballs can fit into the box. However, this is a simplistic estimation as it neglects factors such as the packing efficiency or the potential spaces between the balls.

11 because when you count from the extreme right end '0' and come counting to the left side, you skip 11 numbers till you reach the first number '1'. And when you put a decimal after 1st number, so the last '0' is at the 11th place, that is why it is [tex]10^{11}[/tex] .
