Can anyone write the equation of the graph?

We have an absolute value function that opens upwards. The interval where it is decreasing only is:

(-∞, 2)

All absolute value equations of the form:

y = |x - a| + b

have graphs that open upwards, and a vertex in the point (a, b).

While ones of the form:

y = -|x - a| + b

have graphs that open downwards, and again, a vertex in the point (a, b).

In this case we have one that open upwards:

h(x)=|x-2|+6

With a vertex at (2, 6)

The function will be decreasing on the left side of the vertex, so the interval where the function is only decreasing is:

(-∞, 2)

The 4 possible solutions in the context of the problem are (0, 8), (3, 6), (6, 3), and (9, 2)

Given the equation that models the situation expressed as:

4x + 6y = 48

We are to find 4 possible solutions for x and y. Note that the values of x and y must be integers.

If there are no cars i.e. at when x = 0

4(0) + 6y = 48

0 + 6y = 48

6y = 48

y = 48/6

y = 8

One of the solution is (0, 8)

If there are 3 cars, i.e. at when x = 0

4(3) + 6y = 48

12 + 6y = 48

6y = 48 - 12

y = 36/6

y = 6

The second solution will be (3, 6)

If there are 6 cars, i.e. at when x = 6

4(6) + 6y = 48

24 + 6y = 48

6y = 48 - 24

y = 24/6

y = 4

The third solution will be (6, 3)

If there are 9 cars, i.e. at when x = 9

4(9) + 6y = 48

36 + 6y = 48

6y = 48 - 36

y = 12/6

y = 2

The fourth solution will be (9, 2)

Hence the 4 possible solutions in the context of the problem are (0, 8), (3, 6), (6, 3), and (9, 2)

Answer:

  45,000

Step-by-step explanation:

Given a 30 minute sample of a constant stream shows 2250 people entered the gate, you want an estimate of the total number of people through the gate in 10 hours.

A half-hour period is 1/20 of the 10-hour period the gate was open. The rate is assumed constant, so the 2250 people entering in that half-hour period is presumed to be 1/20 of the total attendance.

  20 · 2250 = 45000

The estimated festival attendance is 45,000 people.

The probability that x < y is 1/8 or 0.25 .

What is probability of an event?
The possibility or chance of an event happening is commonly believed to be the probability of it happening. In the most basic scenarios, the probability that a specific event 'A' will occur as a result of an experiment is calculated by dividing the number of ways that 'A' can happen by the total number of possible outcomes.
P(A) = Number of events concerning 'A' / Total events in consideration.

Given, the vertices of the rectangle are (0, 0), (4, 0), (4, 1), (0, 1).
On carefully analyzing and plotting the vertices roughly, we get that the given rectangle has a width of 4 units and a height of 1 unit.
Therefore, the area of the given rectangle = Width*Height = 4*1 = 4 units²
Also, it can be assessed that the line x = y passes through the points of the rectangle at (0, 0) and (1, 1).
Thus, the area for which x < y will be an isosceles triangle with side length of 1 units and co-ordinates of vertices as (0, 0), (0, 1) and (1, 1).
The area of the isosceles triangle thus assumed = 0.5 × 1² = 0.5 units²
Probability that x < y is P(E): 0.5/4 = 1/8 = 0.25
Therefore, the probability that x < y is 1/8 or 0.25 .

the probability would be taking a purple one. there are only 2 red beads

3/2 or 2/3

The probability that the two beads selected from the bag at random is purple or red is 5/8.

It is the chance of an event to occur from a total number of outcomes.

The formula for probability is given as:

We have,

Total number of beads = 8

2 of the beads are blue.

1 of the beads is green.

3 of the beads are purple.

Red beads = 8 - (2 + 1 + 3) = 8 - 6 = 2

Now,

The probability that the two beads selected are purple or red.

= Probability that the two beads are purple + Probability that the two beads are red.

= 3/8 + 2/8

= 5/8

Thus,

The probability that the two beads selected are purple or red is 5/8.

Answer: 92

Step-by-step explanation:

The value of x in the equation is $55 and this represents the cost of the expensive book

The variable x is not defined in the question

So, we represent x as the more expensive book and y to represent the less expensive book

Also, from the question we understand that

The above statements can be interpreted to the following equations

x = 4 + 3y

x + y = 72

Substitute x = 4 + 3y in the equation x + y = 72

So, the equation x + y = 72 is represented as

4 + 3y + y = 72

Evaluate the like terms in the above equation

4 + 4y = 72

Collect the like terms in the above equation

4y = 72 - 4

Evaluate

4y = 68

Divide both sides by 4

So, we have

y = 17

Substitute 17 for y in the equation x = 4 + 3y to solve for x

x = 4 + 3 * 17

Evaluate the products

x = 4 + 51

Evaluate the sum

This gives

x = 55

The abbreviation is cos

cos(θ) = adjacent / hypotenuse

Consider that;

[tex]X = \sqrt{a^2+b^2-2abcosX}[/tex] (using law of cosine)

[tex]X = \sqrt{21^2+18^2-2\times 21\times 18\times cos(123 ^\circ)}[/tex]

[tex]X = \sqrt{441+324-756\times (-0.5446)}[/tex]

X = 34.30 yd

If A, B, and C are the measures of the angles of an oblique triangle, and a, b, and c are the lengths of the sides opposite the corresponding angles, then the square of a side of the triangle is equal to the sum of the squares of the other two sides minus twice the product of the two sides and the cosine of the included angle.

Step-by-step explanation:

12÷3=4

Step-by-step explanation:

so, after clarification from your side, we know

f(x) = 12500 × (0.82)^x

so, with every new year we are multiplying the value of the previous year by 0.82.

in other words

f(n) = f(n-1) × 0.82

with f(0) = 12500

because anything to the power of 0 equals 1.

A

so, the price is decreasing every year, because any multiplication with a positive value smaller than 1 decreases the original number.

multiplying an amount by a decimal number like 0.82 creates exactly 82% of the original amount because 1 represents 100%.

that means the value decreases every year by 100 - 82 = 18% compared to the value of the previous year.

B

1 5600

2 3136

3 1756.16

4 983.45

remember, Part A showed always an 18% decrease over the previous year.

from 5600 to 3136, this was a change of

100% = 5600

1% = 100%/100 = 5600/100 = $56

the price difference was 5600 - 3136 = 2464

how many % was that decrease ?

as many as how often 1% fits into 2464 :

2464 / 56 = 44%

that was much more than Part A.

from 3136 to 1756.16, this was a change of

100% = 3136

1% = $31.36

the price difference was 3136 - 1756.16 = $1,379.84

how many %

1,379.84 / 31.36 = 44%

again.

from 1756.16 to 983.45, this was a change of

100% = 1756.16

1% = $17.5616

the price difference was 1756.16 - 983.45 = 772.71

hire many %

772.71 / 17.5616 = 43.99997722...%

and again 44% (just a little rounding uncertainty).

so, product B recorded a much greater percentage change in value over the previous year than product A :

Step-by-step explanation:

Time taken by bus to travel from Las Vegas to salt lake city is 6.41 hours.

Here it is given that bus travel from La to Lv in 4 hours and the distance between them is 265 miles.

We have to find the time taken to travel from Las Vegas to salt lake city whose distance between them is 425 miles.

Formula to find the speed is:

Speed = Distance / Time

Distance = 265 miles

Time = 4 hours

Speed = 265/4

= 66.25 miles/ hour

From this, we can find the time taken to travel from Las Vegas to salt lake city.

Distance = 425 miles

Speed = 66.25 miles/ hours

Speed = Distance/time

Time = Distance / Speed

= 425/ 66.25

The given inequality is 5x+6≤2x+15.

Mathematical expressions with inequalities are those in which the two sides are not equal. Contrary to equations, we compare two values in inequality. Less than (or less than or equal to), greater than (or greater than or equal to), or not equal to signs are used in place of the equal sign.

Here, the inequality can be solved as follows

5x+6≤2x+15

Subtract 6 on both the sides of the inequality, we get

5x+6-6≤2x+15-6

5x≤2x+9

Subtract 2x on both the sides of the inequality, we get

5x-2x≤2x+9-2x

3x≤9

Divide 3 on both the sides of the inequality, we get
