Answer:
The graph is the shape of an inverted "V" and opens downwards.
The vertex of the graph is (-4, -5) and its axis of symmetry is x = -4.
When x > -4, every time x increases by 1 unit, y decreases by 1 unit.
When x < -4, every time x decreases by 1 unit, y decreases by 1 unit.
Step-by-step explanation:
Absolute value
The bars either side of an expression or a value are the absolute value symbols. "Absolute value" means how far a value is from zero. Therefore, the absolute value of a number is its positive numerical value.An absolute value function is a function that contains an algebraic expression within absolute value symbols.-----------------------------------------------------------------------------------------
General form of an absolute value function
\(y=a|x-h|+k\)
where:
a controls the width of the "V".(h, k) is the vertexIf a > 0 the graph opens upwards.Given absolute value function:
\(y=-|x+4|-5\)
Graph of the given absolute value function:
As a < 0, the graph is the shape of an inverted "V" and opens downwards. The vertex of the graph is (-4, -5).Its axis of symmetry is x = -4. When x > -4, every time x increases by 1 unit, y decreases by 1 unit.When x < -4, every time x decreases by 1 unit, y decreases by 1 unit.helpp me asap please

Step-by-step explanation:
2x?=8
?=4
so therefore the pattern is:
liters of punch x 4
or
number of servings divided by 4
hope this helped! if im wrong please correct me and no hard feelings!
Answer:
Litters of Punch: 2, 3, 5, 6
Number of Servings: 8, 12, 20, 24
Step-by-step explanation:
What I did was find how much 1 liter of punch was, so I divided 8 by 2 and got 4. Every 1 is 4 so then I looked for how many litters would 12 servings be, I divided 12 by 4 and got 3. For the next one, I multiplied the 5 by 4 and got 20. And for the last one I divided 24 by 4 and got 6.

In the rectangle below, the line MN cuts the rectangle into two regions. Find x, the length of segment NB, so that the area of the quadrilateral MNBC is 40% of the total area of the rectangle.
The length of segment NB is 0.833
Finding x, the length of segment NBFrom the question, we have the following parameters that can be used in our computation:
The rectangle
The area of the rectangle is
Area = (20 + x) * 10
The area of MNBC is
Area = 1/2 * 10 * (x + 20 + x - 5)
Area = 5(2x + 15 )
The area of the quadrilateral MNBC is 40% of the total area of the rectangle
So, we have
5(2x + 15) = 40% * (20 + x) * 10
5(2x + 15) = 4* (20 + x)
When evaluated, we have
x = 0.833

Answer:
X=1
Step-by-step explanation:
The total area of the rectangle is 20x10=200
so the area of MNBC is: 40%x200=80
MC= 20-5=15
so (x+15).10/2=80 (according to the trapezoidal area formula)
x=1

Please find the value of x. Show reasons and i'll award brainliest.
First thing we need to do is find the inside angle at point L. Simply take the outside angle of 134 and subtract it from 180. 180-134 = 46. We then do the same for point M. 180-84 = 96. Finally, we add these together then subtract the sum from 360. 46+96 = 142. 360 - 142 = 218. The value of x is 218. Hope this helps!

Part A: To draw triangles ABC and DEC separately, follow these steps:
Draw a line segment DE with a length of 1.2 feet. This will be the base of both triangles.At point D, draw a perpendicular line segment DC with a length of 2 feet. This will be the height of triangle DEC.At point E, draw a line segment EB with a length of 0.3 feet. This will be the height of triangle ABC.Connect points C and B with line segment BC. This will be the hypotenuse of both triangles.What is the others about?The lengths of sides BC, DE, and EC are as follows:
BC: It is the hypotenuse of triangle ABC and has a length that needs to be calculated using the Pythagorean theorem.DE: It is the base of both triangles and has a length of 1.2 feet.EC: It is the height of triangle DEC and has a length of 2 feet.Part B: To find side AB of triangle ABC, we can use the concept of similarity and ratios. Since triangles ABC and DEC are similar, their corresponding sides are proportional. We can set up the following proportion:
AB/DE = BC/EC
Plugging in the given values, we get:
AB/1.2 = BC/2
To solve for AB, we can cross-multiply and then divide:
AB = (BC/2) x 1.2
Now we need to find the value of BC. We can use the Pythagorean theorem, as BC is the hypotenuse of triangle ABC. The Pythagorean theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
BC² = AB² + BE²
Plugging in the given value for BE, we get:
BC^2 = AB² + 0.3²
Now we can substitute the value of AB from the previous equation into this equation:
BC² = ((BC/2) * 1.2)² + 0.3²
Simplifying, we get:
BC² = 0.36 x BC^2/4 + 0.09
Multiplying both sides by 4 to eliminate the fraction, we get:
4 x BC² = 0.36 x BC² + 0.36 + 0.09
Combining like terms, we get:
4 x BC² = 0.36 BC² + 0.45
Subtracting 0.36 x BC² and 0.45 from both sides, we get:
3.64 x BC² = 0.45
Dividing both sides by 3.64 to isolate BC², we get:
BC² = 0.45 / 3.64
Taking the square root of both sides to solve for BC, we get:
BC ≈ √(0.45 / 3.64)
BC ≈ 0.357 feet
Now we can substitute the value of BC back into the equation for AB:
AB = (BC/2) x 1.2
AB ≈ (0.357/2) x 1.2
AB ≈ 0.214 feet
So, the approximate length of side AB of triangle ABC is 0.214 feet.

Original number of students: 56
New number of students: 77
Find the percent of change. Round your answer to the nearest tenth of a percent, if necessary.
Answer:Therefore, the percent change from 56 to 77 students is 37.5%.
Step-by-step explanation:
students, we can use the following formula:
percent change = ((new number - old number) / old number) x 100%
Plugging in the values given in the problem, we get:
percent change = ((77 - 56) / 56) x 100%
percent change = (21 / 56) x 100%
percent change = 0.375 x 100%
percent change = 37.5%
Therefore, the percent change from 56 to 77 students is 37.5%.
Answer: 37.5%

cube? Justify your answer.
Answer:
Step-by-step explanation:
The probability of rolling a number less than or equal to 5 on a fair number cube (also known as a fair six-sided die) is 5/6.
Justification: A fair number cube has six sides, numbered 1 through 6. Out of these six numbers, there are five numbers (1, 2, 3, 4, and 5) that are less than or equal to 5. Therefore, the favorable outcomes are 5, and the total possible outcomes are 6. Thus, the probability is 5/6.

Step-by-step explanation:
5 people can be in a group. There's 12 people. So we can just use combination.
12C5. = 12 * 11 * 10 *9 * 8 = 792
Also, just post one question at a time. We aren't allowed to post multiple answers.
Five people can be in a group. There's 12 people. The combination will be 792 groups
What is the combination?Each of the different groups or selections can be formed by taking some or all of a number of objects, irrespective of their arrangments is called a combination.
The number of r-element combinations of n objects, with repetition is:
\(\overline{C}_{n,k} = \: ^{n + k-1}C_{k} = \dfrac{(n+k-1)!}{k! \times (n-1)!}\)
Thus, 5 people can be in a group. There's 12 people. So we can use combination.
12C5 = 12 * 11 * 10 *9 * 8
12C5 = 792
Five people can be in a group. There's 12 people. The combination will be 792 groups.
