An inequality equivalent to 6x+12≥48 is 3x+6≥24.

What is inequality?

Inequality means not equal. Generally, if two values are not equal, we use the “not equal symbol (≠)”. But to compare the values, whether it is less than or greater than, different inequalities are used.

This is because dividing both sides of the original inequality by 6 results in 3x + 6 ≥ 24.

In option B, C and D, the inequality is not equivalent to the original inequality, as they have different values on one side of the inequality sign.

In option B: 3x+12≥24, the left side of the inequality is greater than the left side of the original inequality.

In option C: 3x+12≥18, the right side of the inequality is lesser than the right side of the original inequality.

In option D: 3x+21≥24, the left side of the inequality is greater than the left side of the original inequality and the right side of the inequality is greater than the right side of the original inequality.

Hence, An inequality equivalent to 6x+12≥48 is 3x+6≥24.

Therefore , the solution of the given problem of inequality comes

out to be  x <-2.

In mathematics, an inequality is a linking of two equations or numbers when there isn't an equal sign. Unbalance therefore precedes inequity. When two numerical values are not equal, an inequality results in a relationship between them. Egality and inequality are not the same. Where variables are not similar or equal, have used the most common symbol (). There are various inequalities that can be utilized to contrast values regardless of how small or huge they are. Switching the two sides it until variables represent all that is left can address a variety of basic inequality problems. The combination or division with low values from both sides are only a few examples of the many factors that might cause inequality. You switch sides and the left.

The sinusoidal function can be represented as:

[tex]$y = A \sin(Bx + C) + D$[/tex]

Where A is the amplitude, B is the b, C is the phase shift, and D is the vertical shift.

Given that the y-intercept is 2, the vertical shift D is 2.

Given that the midline y = 2, the average value of the function is 2, so the sum of the maximum and minimum value is 4 which means the maximum value is 4, the amplitude of the function is 4-2 = 2.

Given that the maximum value of 4 is at [tex]π/4[/tex] , the phase shift C is π/4.

Given that it completes 2 cycles in the interval [0,2π], the frequency B is

When a graph is rising, you must first take the derivative, then set it equal to 0, and last determine out which zero values the variable is positive between.

Explain a graph.

A graph depicts how two variables that are mainly characterized along one of a pair of axes at right angles relate to one another. A typical method for depicting the relationships between data is via graphs. While taking up less space, a graph satisfies the goal of representing the data that are either too many or complex to be clearly specified in the text.

The graph demonstrates that the answer increases from x=-1 to x=2, hence the interval is (-1,2) and the decreasing interval starts at x=-1.

Step-by-step explanation:

The weekly gross pay is 1040. The solution is obtained using arithmetic operations.

What are arithmetic operations?

There are four basic operations which are listed as follows:

•Addition(‘+’): This operation deals with finding the sum.

•Subtraction(‘-’): This operation deals with finding the difference.

•Multiplication(‘×’): This operation deals with finding the product.

•Division(‘÷’): This operation deals with finding the quotient.

Assumption: Weekly working hours are 40.

Since, the hourly rate is 20 per hour and working hours per week are 40

So, the weekly pay comes out to be 40*20= 800

The overtime rate is time and a half which comes out to be

20*1.5= 30 per hour

The overtime hours are 48-40=8 hours

So, the weekly overtime pay comes out to be 8*30= 240

The total pay= 800+240= 1040

Hence, the weekly gross pay is 1040.

The error is to find the solution of system of equations.

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

We have to given that;

The system of equations are,

⇒ a + b = 7   .. (i)

And 1.29a + 0.49b = 6.63 .. (ii)

Now, We can solve the system of equations as;

Here, The system of equations are,

⇒ a + b = 7  

⇒ a = 7 - b .. (i)

And, ⇒ 1.29a + 0.49b = 6.63 .. (ii)

Substitute the value of a from (i) in (ii), we get;

⇒ 1.29a + 0.49b = 6.63

⇒ 1.29(7 - b) + 0.49b = 6.63

⇒ 9.03 - 1.29b + 0.49b = 6.63

⇒ - 0.8b = 6.63 - 9.03

⇒ - 0.8b = - 2.4

⇒ 0.8b = 2.4

⇒ b = 2.4 / 0.8

⇒ b = 3

And, From (i);

⇒ a = 7 - b .. (i)

⇒ a = 7 - 3

⇒ a = 4

We can start solving this problem using algebra. Let x be the price of the lower section seats. Then the price of the upper level seats is x - 10.

We know that there are a total of 8000 seats in the arena, and 3000 of them are upper level seats. So the remaining seats are in the lower section, which means there are 5000 lower section seats.

We also know that the total revenue for a sellout is $194,000. We can use this information to set up an equation to represent the total revenue:

(x - 10) * 3000 + x * 5000 = 194000

Now we can use this equation to solve for the price of the lower section seats (x).

3000(x-10) + 5000x = 194000

3x - 30,000 + 5x * 10^4 = 194000

8x = 224,000

x = 28000/8 = 3500

Therefore, the price of the lower section seats is $3500 and the price of the upper level seats is $3500 - $10 = $3490.

Hi there!  |2x + 1| (greater than or equal to) 3.  So the absolute value of an equation always results in a positive equation.   If you haven't done negative integers yet, here..

So |2x + 1| is greater than or equal to 3.  The number for x can be negative, since the equation is always turned positive.  |2(-1) + 1| = 3 is 2(1) + 1 = 3.  So yes, -1 would work.  But then again, positive 1 will work too!

Fractions are referred to in mathematics as the components of a whole. The entire can be a single item or a collection of items. When we slice a cake in real life, the portion represents the proportion of the cake that was originally cut. The word "fraction" has its roots in Latin. "Fractus" is the Latin word for "broken."

Given that the relationship between the mass m in kilograms of an organism and its metabolism P in Calories per day can be represented by P = 73.3m^3

The definition of an equation in algebra is a mathematical statement that demonstrates the equality of two mathematical expressions. For instance, the equation 3x + 5 = 14 consists of the two equations 3x + 5 and 14, which are separated by the 'equal' sign.

P = 73.3m^3

586.4 = 73.3m^3

F and G are inverse if both of them satisfy the condition h(x)=x. f(g(x))=g(f(x))=x, as we discovered. The argument f(x) and g(x) are inverse functions is thus established.

If f (x) and g (x) are inverse functions, it can be determined using one of two ways. For more information, see the explanation.

Explanation:

Instance 1

Inverse functions of both functions can be found using the first method.

Example.

Inverse of f (x) = x + 7 is what we're looking for.

We attempt to determine x using the equation y = x + 7.

y = x + 7

Inferring that g (x) is the inverse of f (x) from the fact that x = y 7

Finding g (x inverse )'s is now necessary.

g( x ) = x − 7

y = x − 7

x = y + 7

As a result, we discovered that f (x) is the inverse function of g (x).

f and g are equal if g is inverse of f and vice versa.

The second approach entails locating the compound functions f ( g ( x ) ) and g ( f ( x ) ). In this case, f and g are inverse if they are both h (x ) = x.

Example:

f ( g ( x ) =  [ x − 7 ] + 7

G ( x ) placed as x is the expression in brackets.

f ( g ( x ) ) = x − 7  + 7 = x

g (f ( x ) =  [ x + 7 ] − 7

f ( x ) inserted as x is the expression in brackets.

g ( f ( x ) ) = x + 7 − 7 = x

The equation f ( g ( x ) ) = g ( f ( x ) ) = x was what we discovered. The argument f (x) and g (x) are inverse functions is thus established.
