What is the solution to 3/(2x+1) = 9/3x?

Answer:

x = - 3, x = 2

Step-by-step explanation:

Given

x² + x - 6 = 0 ← in standard form

To factorise the quadratic

Consider the factors of the constant term (- 6) which sum to give the coefficient of the x- term (+ 1)

The factors are + 3 and - 2, since

3 × - 2 = - 6 and 3 - 2 = + 1, hence

(x + 3)(x - 2) = 0 ← in factored form

Equate each factor to zero and solve for x

x + 3 = 0 ⇒ x = - 3

x - 2 = 0 ⇒ x = 2

The cube of a number (n) divided by two can be mathematically represented as n³/2.

The cube of a number is achieved when you raise that number to the power of 3. If we have a number, let's denote it as 'n', and we cube it, and we get n³. Now, if you are to divide the cube of a number by two, the formula would be n³/2. For example, if n = 2, the cube of 2 is 8, divided by two equals 4.

The cube of a number divided by two means that you take a number raise it to the power of 3, and then divide the result by 2. For example, if the number is 4, the cube of 4 is 4 × 4 × 4 = 64. Dividing 64 by 2 gives you a result of 32.

Answer: (-2, 5) Quadrant II

Step-by-step explanation:

For every point in the plane, we will identify the location using an ordered pair of the form (x, y).

The first coordinate, the x-coordinate, will refer to the number which corresponds with the point's horizontal location as determined by the number on the x-axis.

The second coordinate, the y-coordinate, will refer to the number which corresponds with the point's vertical location as determined by the number on the y-axis.

Quadrant II: x-coordinate is negative and y-coordinate is positive.

Answer:

Step-by-step explanation:

f⁻¹(x) is the inverse of f(x).

y = 4x − 9.  To find the inverse, switch x and y and solve for y.

x = 4y − 9

x + 9 = 4y

y = (x + 9) / 4

So the inverse function is:

f⁻¹(x) = (x + 9) / 4

ANSWER

[tex]{f}^{ - 1}(x) = \frac{x + 9}{4} [/tex]

EXPLANATION

The given function is

f(x)=4x-9

Let

y=4x-9

Interchange x and y.

x=4y-9

Add 9 to both sides,

x+9=4y

Divide both sides by 4

[tex] \frac{x + 9}{4} = y[/tex]

[tex]y = \frac{x + 9}{4} [/tex]

Therefore,

Answer:

3:4 is the ratio there are more soda cans

Step-by-step explanation:

There are more sodas than candy bars. Specifically, there are 4 sodas and 3 candy bars, which means there is 1 more soda than candy bars.

To compare the number of sodas to candy bars, we simply look at the quantities given. We have 4 sodas and 3 candy bars. To determine which quantity is greater, we can subtract the number of candy bars from the number of sodas:

Number of sodas - Number of candy bars = 4 - 3 = 1

Since the result is a positive number, it indicates that there are more sodas than candy bars. In this case, there is exactly 1 more soda than candy bars. Therefore, we can conclude that the number of sodas is greater than the number of candy bars.

Answer:

≈ 12.43 ( to 2 dec. places )

Step-by-step explanation:

Given

tan46° = [tex]\frac{x}{12}[/tex]

Multiply both sides by 12

12 × tan46° = x, so

x ≈ 12.43

The value of x is 12.426 in the equation Tan 46° = x/12

Tan 46° represents the ratio of the opposite side to the adjacent side in a right triangle with a 46° angle.

Using the tangent function, we have:

Tan 46° = x/12

To find the value of x, we can multiply both sides of the equation by 12:

12 ×Tan 46° = x

Now, we can calculate the value of x using the tangent of 46°:

x = 12×Tan 46°

x=  12 × 1.03553031374

x = 12.4263637649

Therefore, the value of x is 12.426

Answer:

4 ounces of flour will make 1 cake.

Step-by-step explanation:

16 ounces = 1 pound

16 ounces divided by 4 cakes = 4 ounces for 1 cake

Jesse needs ⅔ pound or 0.125 pounds (2 ounces) of flour to make one cake, calculated by dividing the half-pound bag of flour by the number of cakes it can produce (4 cakes).

Jesse is baking cakes for a bake sale and needs to know how much flour is needed for one cake.

From the information provided, we know that a ½ pound bag of flour is enough to make 4 cakes.

To determine how much flour is needed for one cake, we use a simple division.

To find the amount of flour per cake, we divide the total amount of flour by the number of cakes that can be made from it. That gives us:

½ pound flour ÷ 4 cakes = ⅔ pound flour per cake.

Therefore, Jesse needs ⅔ pound (which is 0.125 pounds or 2 ounces) of flour to make one cake.

June and Stella can together create 12 floral arrangements per hour. To fulfill 372 orders, they would need to work for 31 hours.

This problem is solved by calculating the combined rate of work of June and Stella and then using this to calculate the time it will take to complete the orders. June and Stella can create a total of 12 floral arrangements per hour (6 arrangements each). Therefore, to complete 372 orders, they would need 372 divided by 12 hours.

To perform this calculation, divide 372 by 12:

372 ÷ 12 = 31 hours

June and Stella will need 31 hours to fulfill the 372 Valentine's Day orders.

To find out how many hours June and Stella will need to fulfill the orders, we can use the concept of unit rates. We know that June and Stella each create 6 floral arrangements in 1 hour. So together, they can create 12 floral arrangements in 1 hour. Now, we can set up a proportion using the given information: 1 hour is to 12 floral arrangements as x hours is to 372 floral arrangements. This can be written as: 1/12 = x/372. To solve for x, we can cross-multiply: 12x = 372. Dividing both sides by 12 gives us x = 31. Therefore, June and Stella will need 31 hours to fulfill the 372 orders.

Total Weight of sand =90Kg

Ratio in which sand is divided= 2:3:7

Let x be the fundamental unit in which the sand is divided.

By conservation of mass.

2x +3x + 7x= 90

=> 12x =90

=> x=90/12 =45/6=15/2=7.5

So Amount of sand in small bag=2×7.5=15Kg

Amount of sand in medium bag =3×(7.5)=23.5Kg

Amount of sand in Large bag =7×(7.5)=52.5 Kg

Hope it helps...

Regards;

Leukonov/Olegion.

Add the ratios to find the total shares:

2 + 3 +7 = 12

Divide the total weight by the number of shares:

90 kg/ 12 =7.5 kg per share.

Now multiple each share by the weight per share:

Small = 2 x 7.5 = 15 kg

Medium = 3 x 7.5 = 22.5 kg

Large = 7 x 7.5 = 52.5 kg

Final answer:

The problem involves finding the values of x and y in a parallelogram, using given segment lengths. Without an additional equation, we can only express one variable in terms of the other, resulting in the equation 4 = 3x + 2y.

Explanation:

The question is asking us to find the values of x and y in a parallelogram DEFG, where we know the lengths of some segments inside the parallelogram, specifically DH, HF, GH, and HE. As properties of a parallelogram dictate that opposite sides are equal in length, and segments DH and HF form one side, while segments GH and HE form the opposite side, we conclude that DH + HF must equal GH + HE.

Setting up the equation (x + 2) + (2y) = (4x - 3) + (4y + 1), we combine like terms, which gives us x + 2y + 2 = 4x + 4y - 2. Upon further simplification, by subtracting x and 2y from both sides, we get 4 = 3x + 2y. This equation allows us to express one variable in terms of the other.

Finding a specific value for x and y would require additional information, such as another equation involving x and y to solve this system of equations. Without this, we are limited to only expressing one variable in terms of the other.
