Find the lowest value of the data this box -and-whisker ploy represents 12,1315,16

To create a word problem for the equation '1/2 x + 6 = 81', we can imagine a student earning points on a quiz and receiving additional points, with the task to find out how many points they initially earned.

To create a word problem for the equation 1/2 x + 6 = 81, we can consider a real-world scenario. Imagine that a teacher tells a student that they will receive double the number of points they earn on a special quiz and an additional 6 points for their efforts in the classroom. The total points would then put their score at 81 points for the semester. The question is, how many points did the student earn on the special quiz?

To solve the problem, we follow these steps:

The student earned 150 points on the special quiz before the additional points were added.

Answer:

x^2 - 5x - 6  =  (x - 2)(x - 3).

Step-by-step explanation:

f(x) = x^2 - 5x - 6

We need 2 numbers whose product is - 6 and whose sum is -5. They are   -3 and -2:

The factors are x- 2  and x - 3.

Final answer:

The factors of the expression x²-5x-6 are (x-6)(x+1).

Explanation:

This question demands basic understanding of methods of factorization and finding solutions of an equation.

The method to find factors of an equation, ax² + bx + c = 0, find two numbers that multiply to get c and add to give b.

To find the factors of the expression x²-5x-6, we need to factorize it. We look for two numbers that multiply to give -6 and add to give -5. The numbers -6 and 1 fit these conditions.

So, x²-5x-6

=> x² - 6x + x- 6

=> x(x - 6) +1(x - 6)

=> (x - 6)(x + 1)

Therefore, the factors of the expression are (x-6)(x+1).

Answer:

larger number : 24

smaller number : 10

Step-by-step explanation:

Final answer:

To find the two numbers whose sum is 34 with one being 14 less than the other, equations were set up and solved. The larger number is 24, and the smaller number is 10.

Explanation:

The sum of two numbers is given as 34, and it is known that the smaller number is 14 less than the larger number. To find these numbers, we can set up a system of equations. Let's denote the larger number as L and the smaller number as S. According to the problem, we have two equations:

Substituting the second equation into the first one gives us:

L + (L - 14) = 34

Combining like terms, we get:

2L - 14 = 34

Adding 14 to both sides, we obtain:

2L = 48

Dividing both sides by 2 gives us the value of L:

L = 24

Now that we have the larger number, we can find the smaller number by subtracting 14 from L:

S = 24 - 14

S = 10

The numbers are 24 and 10, with 10 being the smaller number.

Answer:

f⁻¹(x) =  -(x+9) / 5

Step-by-step explanation:

We have given a function.

f(x) = -5x -9

We have to find inverse of given function.

Let y = f(x)

y = -5x-9

Solving above equation for x, we have

x = -(y+9) / 5

Putting x = f⁻¹(y) in above equation ,we have

f⁻¹(y) =  -(y+9) / 5

Replacing y by x, we have

f⁻¹(x) =  -(x+9) / 5 which is the answer.

( x - 2) ( x + 5/7 )

A proportion looks like this:

[tex]a\div b = c\div d[/tex]

It means that the quantity a,b,c and d are in the same proportion: the ratio between a and b is the same ratio between c and d.

They are particularly useful in situation when you have an example given, and you want to extrapolate the relationship for another couple.

For example, you can think of the following problem: "Five apples cost 2 dollars. How much will 8 apples cost?"

You can build the proportion

[tex]5\div 2 = 8\div x[/tex]

And then solve it for x:

[tex]\dfrac{5}{2}=\dfrac{8}{x} \iff 5x=16 \iff x = \dfrac{16}{5} = 3.2[/tex]

Answer:

g(x) = (4/5)x^2 - 2

Step-by-step explanation:

f(x) = (2/5)x^2 - 2 is the equation of a parabola with vertex at (0, -2).

Applying a vertical stretch of factor 2 to f(x) requires multiplying both the slope (2/5) and the y-intercept (-2) by 2:

g(x) = (2)(2/5)x^2 - 4, or

g(x) = (4/5)x^2 - 4.

Answer:

A segment

Step-by-step explanation:

A line is a straight path that is infinitely long.  

A line segment is a section of a line. It consists of two points, which mark the beginning and the end of the segment, and all points in between.

In the diagram, the segment consists of the points A and B and all the points between them.

The line itself extends infinitely both  left and right.

A line segment is the part of a line that encompasses two points and every point between them. It is defined by its extremities, and its characteristic property is that for any three distinct points on it, one must lie between the other two.

The part of a line that contains two points and all other points between them is known as a line segment. Essentially, if you have two points, A and B, the line segment AB includes every point that lies between point A and point B on the straight line that passes through them both. This is captured in geometry by saying that A and B are the extremities of the segment AB and any point C that lies between A and B is part of that segment.

Important properties of a line segment:

If A and C are points on a straight line, there will always be at least one point B such that B lies between A and C.

For any three points situated on a straight line, one of them will always be between the other two.

If four points are considered, they can be arranged in such a way that one of them invariably lies between any two others.

You switch the sign of the y coordinate for point b, so the new b coordinate is (-2,1)

Answer:

(-2,1)

Step-by-step explanation:

The point  b (-2,-1) lies in the third quadrant. A reflection over the x-axis will map the point in the second quadrant. In this quadrant, y is positive while x will still be negative. so we end up with;

(-2,1)

Answer:

Cross multiplying is literally what you do multiplying diagonally.

Step-by-step explanation:

Here you would multiply 12 by 100% and x by 10.

We convert the percents into decimals first.

So 12 * 1 = 12 and x * 0.1 = x/10

So x/10 = 12

Then we multiply each side by 10.

x = 120.

Answer:

C. 40

Step-by-step explanation:

There are 3 sectors that are labeled five, which is out of 12. So the chance of landing on one of it is 3/12, or 1/4.

So, a reasonable estimate is that out of 150 spins, 1/4 of them will land on five. The number of spins can be found out by multiplying 150 by 1/4. 150 * 1/4 is equal to 37.5, which is about 40.

Answer:

916 in.

Step-by-step explanation:

Step by Step.

5*10 = 50, and 50*2 = 100

10*4 = 40, and 40 * 2 = 80

(4*6)/2 = 12, and 12 * 2 = 24

10*10 = 100, and 100 * 2 = 200

16*16 = 256, and 256 * 2 = 512

Adding this together, we get: 916 inches.

Answer: Option A; cos(28°) = 15/17

Step-by-step explanation:

You must remember that for a triangle rectangle we have that:

Sin( angle) = (opposite cathetus)/hypotenuse

cos(angle) = (adjacent cathetus)/hypotenuse

tan(angle) = (opposite cathetus)/(adjacent cathetus)

We want to find the cos(28°), then we can use the second relation, where the adjacent cathetus is 15 units long, and the hypotenuse is 17 units.

cos(28°) = 15/17

Then the correct option is A.

The value of cos(28) = 15/17.

Based on the diagram, the cosine of angle 28 degrees can be determined using the given information. In a right triangle, cosine is defined as the ratio of the length of the adjacent side to the hypotenuse.

Given that the base of the triangle is 15 units and the hypotenuse is 17 units, we can conclude that the adjacent side is the base. Therefore, the adjacent side has a length of 15 units.

Now, we can apply the cosine formula: cos(angle) = adjacent/hypotenuse. Plugging in the values, we have cos(28) = 15/17.

Hence, the cosine of angle 28 degrees, with a base of 15 units and a hypotenuse of 17 units, is approximately 0.882.

Simplify √-y to √yi

3+ 2y = √yi

Square bot sides

(3 + 2y)^2 = -y

Expand

9 + 12y + 4y^2 = -y

Move all terms to one side

9 + 12y + 4y^2 + y = 0

Simplify 9 + 12y + 4y^2 + y to 9 + 13y + 4y^2

9 + 13y + 4y^2 = 0

Split the second term in 9 + 13y + 4y^2 into two terms

4y^2 + 9y + 4y + 9 = 0

Factor out common terms in the first two terms, then in the last two terms

y(4y + 9) + (4y + 9) = 0

Factor out the common term 4y + 9

(4y + 9)(y + 1) = 0

Solve for y

y = -9/4, -1

Check solution

when y = -9/4, the original equation; 3 + 2y = √-y does not hold true. We will drop y = -9/4 from the solution set.

Answer:

What is the equation of the line parallel to the given line with an x-intercept of 4?

y = 4 x +  -16

Step-by-step explanation:

The resulting equation is y = x - 4.

Firstly, a line that is parallel to another line has the same slope. Since the given line is in the form y = mx + b, we need the slope (m) from this equation. Let's assume it is y = x + c, then the slope (m) is 1 since no explicit value is provided for c.

Next, we need the equation of a new line that has the same slope (which is 1) and an x-intercept of 4. An x-intercept of 4 means the line passes through the point (4, 0).

Therefore, the equation of the line parallel to the given one with an x-intercept of 4 is y = x - 4.

Answer:

2 Cups of water

Step-by-step explanation:

To find the amount of water that Arjun will need to make 3 pancakes for each family member in a family of 6, we first need to know what our current ratio of pancake mix to water is.

2/3 water : 1 pancake mix = 6 to 7 pancakes

Now we need to know how much pancakes Arjun needs to make.

6 family members

3 pancakes each

So we multiply the number of family members to the number of pancakes each

Total number of pancakes = 6 x 3

Total number of pancakes = 18

So we need at least 18 pancakes for the family to have 3 pancakes each.

Since we know that the combination of water and pancake mix will make around 6 to 7 pancakes, we simply multiply the entire amount by 3.

2/3 (3) : 1 (3) = 6 (3) to 7 (3)

2 Cups of water : 3 pancake mix = 18 to 21 Pancakes

With a combination of 2 cups of water and 3 pancake mix. We will get 18 to 21 pancakes.

So Arjun will need 2 cups of water to get 18 to 21 pancakes for the family of 6.
