Answer:

x = 1

Step-by-step explanation:

6(x - 2) = 3 - 9x

We want to find x so that LHS = RHS/

6x - 12 = 3 - 9x

6x + 9x = 3 + 12

15x = 15

x = 1

Not 100% sure!

The value of x that makes the equation true is x = 1.

An expression in mathematics is a combination of numbers, variables, and mathematical operations (such as addition, subtraction, multiplication, and division) that represents a value or quantity.

We can solve for x by simplifying the equation using the distributive property and combining like terms:

6(x - 2) = 3 - 9x

6x - 12 = 3 - 9x (distribute 6)

6x + 9x = 3 + 12 (add 9x and 12 to both sides)

15x = 15 (combine like terms)

x = 1 (divide both sides by 15)

Therefore, the value of x that makes the equation true is x = 1.

The equation to determine the volume of the rectangular box is:

V = 6 * (5 + 3x)

Given that the area of the large rectangular package is 6 square units and its height is 3x units more than the small box,

To determine the volume of the large rectangular package, multiply its area by its height.

Volume of the large rectangular package = Area of the large rectangular package * Height of the large rectangular package

The area of the large rectangular package is given as 6 square units, so we substitute it into the equation:

Volume of the large rectangular package = 6 * Height of the large rectangular package

Now, the height of the large rectangular package is 3x units more than the small box. The height of the small box is 5 units, so we add 3x to it:

Height of the large rectangular package = 5 + 3x

Substituting this into the equation:

Volume of the large rectangular package = 6 * (5 + 3x)

Hence, the equation to determine the volume of the large rectangular package is: Volume = 6 * (5 + 3x)

Answer:

Step-by-step explanation:

i) If p is inversely proportional to q³, this is expressed as p ∝ q³

p = k/q³ where q is the proportionality constant.

Given p = 27 and q = 3

Substitute this values into the formula

27 = k/(3)³

27 = k/27

k = 27×27

k = 729

Substitute k = 1 into the formula

p = 729/(q)³

Hence the formula which expresses p in terms of q is p = 729/q³

ii) If r is directly proportional to q, it is expressed as r ∝ q

r = kq

If r = 10 and q = 2

Substitute

10 = 2k

k = 10/2

k = 5

The equation becomes

r = 5q... 1

From 1) p = 729/q³

q³ = 729/p

q = 9/³√p

q = 9/p^1/3....2

Substitute equation 2 into 1

r = 5(9/p^1/3)

r = 45p^-1/3

Compare r = 45p^-1/3 with r = kp^n

k = 45 and n = -1/3

At an elevation of 500m, the sound will travel fastest.

Elevation        Temp

  500m           11.8°C

 1000m           8.5°C

 1500m           5.3°C

 2000m          2.0°C

We know that air molecules at higher temperatures have more energy and can vibrate faster and allow sound waves to travel more quickly because the more is the medium, the more quickly sound waves propagate.

So, when the given temperature is maximum i.e. 11.8°C, the sound will travel fastest. The elevation corresponding to 11.8°C is 500m.

So, Sound will travel fastest at 500m elevation.

Therefore, At an elevation of 500m, the sound will travel fastest.

Answer:

A) [tex]9 *l=54[/tex]

Step-by-step explanation:

The area of a rectangle is w*l=A, where w is the width and l is the length.

In this question, we are given 2 of the variables. We are told that the width is 9 and the area is 54. So, to find the equation that represents this situation, simply plug in the values.

Then, if needed we can find the length of the rectangle. Through the division property of equality, we know that dividing both sides of the equation maintains the equality of the equation. So, we can divide both sides by 9 to isolate the variable.

[tex]y = 5[/tex]

Step-by-step explanation:

Given equation:

[tex]3(3y - 15) = 0[/tex]

Divide both sides by 3:

[tex]\implies \dfrac{3(3y - 15)}{3} = \dfrac{0}{3}[/tex]

[tex]\implies 3y-15 = 0[/tex]

Add 15 to both sides:

[tex]\implies 3y-15 +15= 0+15[/tex]

[tex]\implies 3y=15[/tex]

Divide both sides by 3:

[tex]\implies \dfrac{3y}{3}=\dfrac{15}{3}[/tex]

[tex]\implies y=5[/tex]

Answer:

The value of y is 5.

Step-by-step explanation:

First, we will distribute 3 on (3y - 15) This means 3(3y) - 3(15) = 0. Now, we will multiply 3 by what is inside the parentheses for each value. This gives us 9y - 45 = 0. After that, we will add 45 to both sides, which leaves us with 9y = 45. Finally, we will divide 45 by 9 to give us the y value, 5. I hope this helped (:

Step-by-step explanation:

Then all factors of the function f(x) = x³ – 2x² – 68x – 120 is (x + 2), (x + 6), and (x – 10).

It is the method to separate the polynomial into parts and the parts will be in multiplication. And the value of the polynomial at this point will be zero.

If f(–2) = 0, that mean one root is –2.

The function f(x) = x³ – 2x² – 68x – 120

We have the one factor is (x + 2)

Then the function can be written as

f(x) = (x + 2)(x² – 4x – 60)

f(x) = (x + 2)(x² – 10x + 6x – 60)

f(x) = (x + 2)[(x(x – 10) + 6(x – 10)]

f(x) = (x + 2)(x – 10)(x + 6)

The domain of the provide function where the function is defined is x less than the number three.

Domain of a function is the set of all the possible input values which are valid for that function.

The function given in the problem is,

The above function is the function of logarithm. For the logarithmic function, it is defined for all the real numbers except 0.

Thus, the function should be greater than zero as,
