Each crate holds 6 dozen eggs.
1 dozen = 12 eggs.
Multiply 12 by 6 to get the total number of eggs per crate:
6 x 12 = 72 eggs per crate.
The box holds 4 crates, multiply the number of each in a crate by the number of crates:
72 eggs x 4 crates = 288 total eggs.
Find the derivative of y = 2(x^2) - x + 4 at x = 2
Answer:
7.
Step-by-step explanation:
y = 2x^2 - x + 4
The derivative y' = 2*2x^(2-1) - 1
= 4x - 1
At x = 2 y' = 4(2) - 1 = 7.
Answer:
7
Step-by-step explanation:
Differentiate using the power rule
[tex]\frac{d}{dx}[/tex](a[tex]x^{n}[/tex]) = na[tex]x^{n-1}[/tex]
Given
y = 2x² - x + 4, then
[tex]\frac{dy}{dx}[/tex] = (2 × 2)x - 1 = 4x - 1
At x = 2 ⇒ [tex]\frac{dy}{dx}[/tex] = (4 × 2) - 1 = 8 - 1 = 7

solve log2 [log3 (log4 x)]=0
Solving the nested logarithmic equation log2 [log3 (log4 x)] = 0 requires repeatedly using the concept that y = logb(x) is equivalent to x = by, resulting in x = 64.
Explanation:To answer your question, we'll need to understand that logarithmic expressions such as log2 [log3 (log4 x)]=0 can be solved by step-by-step process called exponentiation.
First, knowing that y = logb(x) is equivalent to x = by, we can re-write the equation log2 [log3 (log4 x)] = 0 as log3 (log4 x) = 20.
Then, using the concept that the logarithm of a number raised to an exponent is the product of the exponent and the logarithm of the number, move forward to solve log4 x = 31.
Finally, applying the same rule once more gives us x = 43 = 64.

2x - 5x + 5 - 4
x + x + x +3 + 5 - 2
6x - 7 + 3x + 5
3 + 2(2x + 5)
Answer: 3/4 (8x + 16) simplified expression is 6x + 12
2x - 5x + 5 - 4 simplified expression is -3x + 1
x + x + x +3 + 5 - 2 simplified expression is 3x + 6
6x - 7 + 3x + 5 simplified expression is 9x - 2
3 + 2(2x + 5) simplified expression is 4x + 13
Step-by-step explanation:
3/4 (8x + 16) in the example the 3 is multiplying and the 4 is dividing,
so you can start with multiplication, multiply the 3 for each value into the parenthesis after that you can place 4 as the divisor of this equation
(3 * 8x + 3 * 16) / 4
after we perform this equation the product is the following
(24x + 48) / 4
after this step you can divide the each value into the parenthesis between 4, this process give us separate equations.
(24x/ 4) + (48/4)
if you proceed with the division of each value we will find the last equation.
(24x/ 4) = 6x
(48/4) = 12
then the simplified expression is 6x + 12.
2x - 5x + 5 - 4, with this case you can resolve the equation with the similar values, for example, you can start with the values that has the x, and after that proceed with the simple values.
2x - 5x = -3x
5 - 4 = 1
after we resolve this, you only need placed the values with its sign in one equation then the simplified expression is -3x + 1.
x + x + x +3 + 5 - 2, in this example you can start with the sum of x, and after that proceed with sum of the simple values.
x + x + x = 3x
3 + 5 - 2 = 6
after that we place the values in one expression , then the simplified expression is 3x + 6.
6x - 7 + 3x + 5, in this equation we can star with the similar values, the values with x and after that the simple values
6x + 3x = 9x
-7 + 5 = -2 ( as the 7 is bigger than 5 the result get value of the biggest number.
after you only need to place the values in one equation, then the simplified expression is 9x - 2.
3 + 2(2x + 5), with this example you can start with the product of 2 with the values into the parenthesis.
2 * (2x + 5) the 2 is passing to multiply each value into the parenthesis.
2 * 2x + 2 * 5
4x + 10
after that we can place the result of this product in the first equation
3 + 4x + 10
after that you only need to sum the similar values and we get that the simplified expression is 13 + 4x

Find the value of a for which the solution of the inequality is all real numbers.
3x+8+2ax≥3ax−4a
How do I solve for a and what does a stand for please help meeeeeee.
Answer:
[tex]a=3,\text{ then } x\in(-\infty,\infty)\\ \\a\in(-\infty,3),\text{ then }x\in \left[\dfrac{-4a-8}{3-a},\infty\right)\\ \\a\in(3,\infty),\text{ then }x\in \left(-\infty, \dfrac{-4a-8}{3-a}\right][/tex]
Step-by-step explanation:
In the inequality
[tex]3x+8+2ax\ge 3ax-4a\ \ \ (1)[/tex]
a is an arbitrary real number.
Separate the terms with x into left side and the terms without x in the right side:
[tex]3x+2ax-3ax\ge -4a-8\\ \\3x-ax\ge -4a-8\\ \\(3-a)x\ge -4a-8\ \ \ (2)[/tex]
First, look at the leading coefficient at x. If this coefficient is equal to 0 (when [tex]a=3[/tex]), then the inequality is
[tex]0\ge -4a-8\\ \\0\ge -12-8\ [\text{Substituted }a=3]\\ \\0\ge -20[/tex]
This is true inequality for all x, so at [tex]a=3,[/tex] the inequality (1) has the solution [tex]x\in (-\infty,\infty)[/tex]
Now, if the leading coefficient
[tex]3-a>0\\ \\a<3,[/tex]
then we can divide the inequality (2) by this positive number [tex]3-a[/tex] and get
[tex]x\ge \dfrac{-4a-8}{3-a}[/tex]
If the leading coefficient
[tex]3-a<0\\ \\a>3,[/tex]
then we can divide the inequality (2) by this negative number [tex]3-a[/tex] and get
[tex]x\le \dfrac{-4a-8}{3-a}[/tex]
So, the answer is
[tex]a=3,\text{ then } x\in(-\infty,\infty)\\ \\a\in(-\infty,3),\text{ then }x\in \left[\dfrac{-4a-8}{3-a},\infty\right)\\ \\a\in(3,\infty),\text{ then }x\in \left(-\infty, \dfrac{-4a-8}{3-a}\right][/tex]

In a given rectangle, the longer sides are 7 units longer than the shorter sides. If we let the shorter sides be represented as x, write an expression below that represents the perimeter.
A
2x + 7
B
4x2 + 49
C
4x + 49
D
4x + 14
Answer: D because the two longer sides are 7 unites longer, meaning you need to add 14 (7x2) to the final product
Answer:
Option D [tex]4x+14[/tex]
Step-by-step explanation:
Given: The longer sides are 7 units longer than the shorter sides. The shorter side is x.
To find: Write an expression below that represents the perimeter.
Solution: It is given that the shorter side is x.
The longer side is 7 units longer than the shorter side. So, the longer side is [tex]x+7[/tex]
We know that the perimeter of the rectangle is [tex]2(\text{length}+\text{breadth})[/tex]
So, the expression for the perimeter
[tex]=2(x+x+7)[/tex]
[tex]=2(2x+7)[/tex]
[tex]=4x+14[/tex]
Hence, the expression for perimeter is [tex]4x+14[/tex].
So, option D is correct.

Find all natural values of x such that x/8 is a proper fraction, and x/4 is an improper fraction.
The natural numbers for which x/8 is a proper fraction and x/4 is an improper fraction are 4, 5, 6, and 7.
Explanation:Firstly, let's understand what proper and improper fractions are. A proper fraction is a fraction whose numerator is less than the denominator, and an improper fraction is a fraction whose numerator is equal to or greater than the denominator.
Given that x/8 is a proper fraction and x/4 is an improper fraction, we are looking for a number that is less than 8 (for the proper fraction) and equal to or greater than 4 (for the improper fraction). These restrictions on x mean that x must be in the range 4 ≤ x < 8.
When we consider that x should be a natural number, the only numbers that meet this criterion are 4, 5, 6, and 7. Hence, these are the natural values of x for which x/8 is a proper fraction and x/4 is an improper fraction.
Learn more about Proper and Improper Fractions here:https://brainly.com/question/33440318
#SPJ2
Final answer:
The values of x that meet both conditions are 5, 6, and 7.
Explanation:
In order to find natural values for x where x/8 is a proper fraction and x/4 is an improper fraction, we must first understand what proper and improper fractions are. A proper fraction is one where the numerator is less than the denominator, whereas an improper fraction has a numerator larger than or equal to the denominator. Given that x/8 must be a proper fraction, x must be less than 8. For x/4 to be an improper fraction, x must be greater than or equal to 4. Therefore, to satisfy both conditions simultaneously, x must fall within the range of 5, 6, or 7. This is because these are the only natural numbers less than 8 and greater than 4.

What fraction of an inch is 1 cm? I know the answer but don’t know how to show it.
1 cm is approximately 0.394 inches which is the fraction of an inch for 1 cm. This can be discovered by inverting the known relation (1 in = 2.54 cm) or by using dimensional analysis method.
Explanation:The subject of your question concerns the conversion between the units of length, centimeters and inches. In measurement, it is known that 1 inch is equal to 2.54 centimeters. However, you asked what fraction of an inch is 1 centimeter. To find this, we need to invert the relation we know. Thus, 1 cm = 1/2.54 inches.
For a clearer understanding, 2.54 cm is exactly 1 inch (by definition). To find the fractional value of 1 cm in inches, we simply take the reciprocal (invert) of 2.54, because we are essentially asking the question, 'How many cm are there in 1 inch?'. This yields about 0.394, and thus 1 cm = 0.394 inch approximately.
Using Dimensional AnalysisAnother method to understand this conversion is dimensional analysis. It tells us that we're able to convert one unit to another as long as the units are in the same dimension (in this case, length). So based on the relation 1 inch = 2.54 cm, we establish the conversion factor of 1/2.54 = 0.394 inch/cm. So 1 cm * 0.394 inch/cm gives us 0.394 inch.
