What are the coordinates of the x-intercept
of the equation? 5x-2y = 25

Based on the segment addition postulate, we have:

19. AB = 11

20. BD = 43

21. CY = 33

22. CD = 32

23. XC = 11

24. CZ = 44

25. ST = 24

26. AC = 20

Given the following:

AB = BC = CX = YZ

AD = 54

XY = 22

XZ = 33

Applying the segment addition postulate, we would have the following:

19. AB = YZ

YZ = XZ - XY

Substitute

YZ = 33 - 22

YZ = 11

AB = YZ = 11

AB = 11

20. BD = AD - AB

Substitute

BD = 54 - 11

BD = 43

21. CY = XY + CX

CX = AB = 11

Substitute

CY = 22 + 11

CY = 33

22. CD = AD - 2(AB)

CD = 54 - 2(11)

CD = 32

23. XC = AB = 11

XC = 11

24. CZ = CX + XY + YZ

CZ = 11 + 22 + 11

CZ = 44

25. 4x + 12x = 32 [segment addition postulate]

16x = 32

x = 2

ST = 12x = 12(2)

ST = 24

26. 14 + 3x - 4 = 4x + 4 [segment addition postulate]

10 + 3x = 4x + 4

10 - 4 = 4x - 3x

6 = x

x = 6

AC = 4x + 4 = 4(6) - 4

AC = 20

Answer:

8 + 3x < 2 + x the answer would be x<-3

2x + 23 ≤ 11 the answer would be [tex]x\leq -6[/tex]

1)  8 + 3x < 2

To solve this, you first want to subtract 8 from both sides to isolate 3x on one side.

This gives you 3x < 2 - 8, which can be simplified to 3x < -6.

After you have this, you want to get x on its own. To do this, divide both sides of the inequality by 3 to get x < -6

2)  2x + 23 [tex]\leq[/tex] 11

For this one, we use the same steps. First, subtract 23 from both sides to isolate 2x, giving us 2x [tex]\leq[/tex] 11 - 23, which we simplify down to 2x [tex]\leq[/tex] -12.

From here, we divide both sides of the inequality by 2 to get x on its own. This gives us x [tex]\leq[/tex] -6

Answer:

Step-by-step explanation:

A bisector splits an angle into two congruent parts.

The exact trigonometric ratios for the angle x is second quadrant.

Given Radian equals to θ = 27π / 4, we need to find all the Trigonometric ratios for the same -

Lets calculate the value of θ first.

We know π equals 180 degree angle and 2π equals 360 degree, hence with each 2π the radian moves back to zero degree. Which means

θ = 27π / 4 can be reduced to θ = 3π / 4

Hence θ = 135 degree which can be represented as below -

As This lies in second quadrant, hence  on x-axis (Value of base , needs to be taken as -1)

sin θ = 1/√2                            cosec θ = √2

cos θ = -1/√2                          sec θ = - √2

tan θ = -1                               cot θ = - 1

Trigonometric ratios are based on the value of the ratio of sides of a right-angled triangle and contain the values of all trigonometric functions. The trigonometric ratios of a given acute angle are the ratios of the sides of a right-angled triangle with respect to that angle.

The formula for the surface area S of a right cone is S=πr2+πrl, where r is the radius of the base and l is the slant height.

To find

The height of the cone.?

So, according to the question

We have,

The surface area of the cone = The volume of the cone.

We know that

The surface area of the cone,

  S = πr²+πrl

And,

The volume of the cone,

 V = [tex]\frac{1}{3} \pi r^2h[/tex]

So, from question

The surface area of the cone = The volume of the cone

  S = V              

Now, put the all values,

 πr²+πrl =  [tex]\frac{1}{3} \pi r^2h[/tex]

πr(r+ l)  =  [tex]\frac{1}{3} \pi r^2h[/tex]

 (r+l) =  [tex]\frac{1}{3}[/tex] × [tex]\frac{\pi r^2h}{\pi r}[/tex]

The cost percentage is 3.61 %.

A cost is the worth of money that has been expended in the production or delivery of a good or service and is therefore no longer accessible for use in accounting, retail, research, or accounting.

A percentage is calculated by dividing a value or a number by its sum, then multiplying the result by 100. The percentage calculation formula is ( value / total value) × 100%.

The cost of all ingredients mixed in the stew is $2.76.

The total sales is $435.98.

57 gallons of stew are sold per week.

Therefore, the total sales per week is

= $2.76 × 57 = $157.32

Hence, the cost percentage of food is:

= ( 2.76 × 57 ) / 435.98

= 157.32 / 435.98

= 0.361

= 3.61 %

Greetings from Brasil...

Let Ca be the function for Plan A and Cb the function for Plan B.

According to the problem statement, we can conclude that:

where C is the cost and n is the number of videos

Cost that the user will pay for having watched n videos

Ca = cost of Plan A

Cb = cost of Plan B

Is there any point (n) that Ca will be equal to Cb??? Let's equate the functions to check if there is a common point and if there is, what would it be.

Ca = Cb

3n + 8 = 5n

2n = 8

n = 4

In n = 4 we have a condition for the cost that does not matter Ca or Cb.

I will present 2 ways to solve:

1 - building the graph of the functions and observing the points where the Y axis (cost axis) its smaller

2 - assigning 2 points - below n = 4 and above n = 4 - to observe the cost behavior

1 - see attachment

2 - let's choose the points n = 1 and n = 10 (as already said, n=4 does not matter Ca or Cb - meeting point / intersection point)

n = 1

Ca(1) = 3.1 + 8 = 11

Cb(1) = 5.1 = 5

Ca > Cb, then Cb better to the user

n = 10

Ca(10) = 3.10 + 8 = 38

Cb(10) = 5.10 = 50

Ca < Cb, then Ca better to the user

We can come to the following conclusion:

0 < n < 4 → better use Plan B (in this interval the cost to the user will be lower with Plan B)

n = 4 → It doesn't matter to use Plan A or Plan B.

n > 4 → better use Plan A (for n above 4 the cost to the user will be lower with Plan A)

Answer:

To solve for x, the equation -fx -g = h is correctly rewritten as x = -h/f - g/f.

An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.

Given the equation in the question;

-fx - g = h

Solve for x.

To solve for x simply means to make x the subject of the formula or equation.

-fx - g = h

Add g to both side

-fx - g + g = h + g

Negative g and positive g cancels out.

-fx = h + g

Now, divide each term in the equation by the coefficient of x

-fx/-f = h/-f + g/-f

x = -h/f + (-g/f)

x = -h/f - g/f

Therefore, to solve for x, the equation -fx -g = h is correctly rewritten as x = -h/f - g/f.
