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.

100 pennies equals 1 dollar so 3 over 100 is the fraction

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

What does a math equation mean?

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.

We can use this equation to find the mass of an organism that has a metabolism of 586.4 calories per day.

P = 73.3m^3

586.4 = 73.3m^3

m^3 = 8

m = ∛8

m = 2

So the mass of an organism that has a metabolism of 586.4 calories per day is 2 kilograms.

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.

Answer:

HELP you find the perimeter of what? you didnt link it.

Step-by-step explanation:

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.

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

According to the available alternatives, the right answer is 2 because x=2 and finishes at x=3.

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..

|-4| = 4

|-3| = 3
|-2| = 2

-4 = -4
-3 = -3
-2 = -2

But when you put the absolute value marks next to them, the value turns positive.  :D

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! The value just can't be zero, since that would be 2(0) + 1 = 3, which is 0 + 1 = 3, not true.

Values have to be [1, +infinity] and [-1, -infinity].

The number of points in the second quadrant will be 0.

A coordinate plane is a 2D plane that is formed by the intersection of two perpendicular lines known as the x-axis and y-axis. A coordinate system in geometry is a method for determining the positions of the points by using one or more numbers or coordinates.

As the function is an odd function, it means

f(-x)= -f(x)

So, if you will draw the graph of any of the odd functions, if six points lie in the first quadrant, a similar number of points will be in the third Quadrant, as the two parts will be mirror images of each other.

The other two points will be, one origin (0,0) and the other will be a point on the X-axis.

You can check this, by taking any of the polynomial functions, for example,x, x³, x+x³, etc.

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

Step-by-step explanation:

We can get a more accurate result by combining the two fractions with a common denominator and then rounding.

The ratio can be defined as the number that can be used to represent one quantity as a percentage of another. Only when the two numbers in a ratio have the same unit can they be compared. Ratios are used to compare two objects.

Let's round to the nearest whole number.

8/5 = 1.6 = 2

7/4 = 1.75 = 2

2 + 2 = 4

Now let's find the common denominator:

The least common denominator between 5 and 4 is 20, so change both fractions to denominators of 20:

32/20 + 35/20

Add the numerators and keep the denominator:

67/20

67/20 = 3.35 = 3

Therefore, adding the two fractions using a common denominator and then rounding gives us a closer answer.

if x = 2 we get the answer - 8084, and x = (-5) is 20735. A mathematical equation is a formula that uses the equals sign to represent the equality of two expressions.

The definition of an equation in algebra is a mathematical statement that proves two mathematical expressions are equal.

Consider the equation 3x + 5 = 14, where 3x + 5 and 14 are two expressions that are separated by the symbol "equal."

x = 2

12² + 5(2) - 4122 (2) + 6 = -8084

12² + 5(2) - 4122 (2) + 6

Calculate exponents  12² :144

= 144 + 5(2) - 4122 (2) + 6

Multiply and divide (left to right) 5(2) : 10

= 144 + 10 - 4122 (2) + 6

= 144 + 10 - 8244 + 6

= - 8084

x = -5

12² + 5 (-5) - 4122 (-5) + 6 = 20735

12² + 5 (-5) - 4122 (-5) + 6

12² = 144

Simplifying,

5 (-5) = -25

4122 (-5) = -20610

= 144 - 25 - (-20610) + 6

Then we get,

= -25 - (-20610) = -25 + 20610

= 144 - 25 + 20610 + 6

= 20735

Therefore, if x = 2 we get the answer - 8084, and x = (-5) is 20735
