Answer:

k = 3

Step-by-step explanation:

Given that b varies jointly with c and d and inversely with f then the equation relating them is

b = [tex]\frac{kcd}{f}[/tex] ← k is the constant of variation

To find k use the condition c = 4, d = 9, f = 6 , b = 18, then

18 = [tex]\frac{k(4)(9)}{6}[/tex] = [tex]\frac{36k}{6}[/tex] = 6k ( divide both sides by 6 )

2(3x-2) is the answer

The factors of the expression 6x + 4 will be 2 and (3x + 2).

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The definition of simplicity is making something simpler to achieve or grasp while also making it a little less difficult.

The expression is given as,

⇒ 6x + 4

Factorize the expression, then we have

⇒ 6x + 4

⇒ 2(3x + 2)

The factors of the expression 6x + 4 will be 2 and (3x + 2).

Answer: 6 gifts.

Step-by-step explanation:

I found the question elsewhere and it states that Eve needs 2/3 m for each gift.

Since Eve has 4 m, the number of gifts she can wrap is the 4 m she has divided by the 2/3 m required for each gift.

= 4 ÷ 2/3

= 4 × 3/2

= 12/2

= 6 gifts.

Note: When dividing by a fraction, you can multiply by it's inverse.

Answer:

The solution of the given equations

x = 3 and y =-2.5

Step-by-step explanation:

Step(i):-

  x - 2y = 8 ..(i)

3x = 19 +4y ..(ii)

By using substitution method

substituting  x = 2y +8 in equation (ii)

 ⇒  3( 2y +8) = 19 +4y

⇒   6y +24 = 19 +4y

⇒  6 y - 4y = 19 - 24

⇒   2 y = -5

   [tex]y = \frac{-5}{2} = -2.5[/tex]

Step(ii):-

Substitute 'y' = -2.5 in equation (i) , we get

         x - 2y = 8

   ⇒  x - 2( [tex]\frac{-5}{2}[/tex]) =8

  ⇒  x = 8 -5

      x = 3        

Final answer:-

The solution of the given equations

Answer:

8 1/2 cup servings

Step-by-step explanation:

Hello!

Well to solve this we have to take the total amount of cups of ice cream and divide it amongst the servings.

So :

Total = 4 cups

Serving = 1/2 cup

What we can do since its such a lower number is count it out by increments of 1/2.

Like so :

So, in total, there would be 8 servings of half a cup of ice cream in 4 cups.

I hope this helps!

If you have any questions or concerns feel free to message me or comment! :)

The number of 1/2 ­cup servings are in 4 cups of ice cream are 8.

A division is a process of splitting a specific amount into equal parts.

We need to find the number of 1/2 ­cup servings are in 4 cups of ice cream

A half cup serving is equal to 4 fluid ounces.

Therefore, 4 cups of ice cream is equal to 8 half-cup servings,

since 4 cups is equal to 32 fluid ounces and 32 divided by 4 equals 8.

4/(1/2)

4×2

8 cups

Hence, the number of 1/2 ­cup servings are in 4 cups of ice cream are 8.

Answer:

Multiply ; 40

Step-by-step explanation:

Given that :

Height, H of rectangular chest = H(x) = x+6.

Area of rectangular chest, A(x) = 20√x /3

Recall; Volume of chest = Base area * Height

(X + 6) * 20√x /3

(20x√x /3 ) + (20 * 6√x/3)

(20x√x /3 ) + (20 * 2 * 3√x/3)

(20x√x/3) + 40√x

The correct answer for the drop-down menu is that the first blank is multiply and the second blank is 40.

Based on the fact that we have been given the Height =H of rectangular chest to be:

= H(x) = x+6.

When the Area of rectangular chest:

A(x) = 20√x /3

Note that: Volume of chest = Base area  x Height

Therefore:

(X + 6) * 20√x /3

(20x√x /3 ) + (20 * 6√x/3)

(20x√x /3 ) + (20 * 2 * 3√x/3)

(20x√x/3) + 40√x

Therefore, the correct answer for the drop-down menu is that the first blank is multiply and the second blank is 40.

Answer:

(-∞,∞)

Step-by-step explanation:

The domain is all possible x values of the function

There are no constraints or holes for this and therefore the domain is all real numbers

A function is a relationship between inputs where each input is related to exactly one output.

x values can be ........-5,-4,-3,-2,-1, 0, 1, 2, 3, 4, 5, 6,.........

The reasonable domain for the function f(x) = 10x + 8 is (-∞, ∞).

A function is a relationship between inputs where each input is related to exactly one output.

Example:

f(x) = 2x + 1

f(1) = 2 + 1 = 3

f(2) = 2 x 2 + 1 = 4 + 1 = 5

The outputs of the functions are 3 and 5

The inputs of the function are 1 and 2.

We have,

f(x) = 10x + 8

We can have any real values of x.

f(-2) = -20 + 8 = -12

f(-1) = -10 + 8 = -2

f(1) = 10 + 8 = 18

f(2) = 20 + 8 = 28

f(3) = 30 + 8 = 28

.

.

.

x values can be ........-5,-4,-3,-2,-1, 0, 1, 2, 3, 4, 5, 6,.........

So,

The domain of the function f(x) = 10x + 8 is -∞ to ∞.

We can write as an interval as,

(-∞, ∞).

Thus,

The reasonable domain for the function f(x) = 10x + 8 is (-∞, ∞).
