Is (3/4)*(a^2/c) less than a with multiple inequalities?

In summary, multiple inequalities are a set of mathematical expressions involving two or more variables being compared using symbols <, >, ≤, or ≥. They can be graphed by plotting each individual inequality and finding the overlapping region, similar to solving a system of equations. Algebraic methods can also be used to solve multiple inequalities. They have various applications in real-life situations, such as budgeting, engineering, and economics.

Homework Statement


I for some reason can't seem do become sure of this.
There are 2 variables x and y. And two constants, a and c, which are both positive.

Homework Equations


x+2y ≤ (3/4)*(a^2/c)
x + 2y < a

The Attempt at a Solution


Does this mean that: (3/4)*(a^2/c) < a ?

Do the inequalities ##A \leq 200## and ##A < 100## imply ##200 < 100?##

@monsmatglad, please check your Inbox. I explained why the inequality isn't necessarily true, based on the info you provided in your earlier thread.
 

1. What are multiple inequalities?

Multiple inequalities refer to a set of mathematical expressions that involve two or more variables being compared using the symbols <, >, ≤, or ≥. These inequalities can be solved to find the range of values that satisfy all of the expressions.

2. How do you graph multiple inequalities?

To graph multiple inequalities, first plot each individual inequality on a coordinate plane. Then, find the region where all of the inequalities overlap. This region represents the solution to the system of inequalities. The solution can be represented by shading the overlapping region or using a dashed line to show the boundary of the solution.

3. How is solving multiple inequalities similar to solving a system of equations?

Solving multiple inequalities is similar to solving a system of equations because both involve finding the values that satisfy a set of expressions. In systems of equations, the solution is a point where the lines intersect, while in multiple inequalities, the solution is a range of values that satisfy all of the expressions.

4. Can you solve multiple inequalities algebraically?

Yes, multiple inequalities can be solved algebraically by using the same methods as solving a single inequality. The key is to isolate the variable on one side of the inequality symbol and then use the appropriate mathematical operations to solve for the variable.

5. How can multiple inequalities be used in real-life situations?

Multiple inequalities can be used in various real-life situations where there are multiple constraints or conditions to consider. For example, in budgeting, multiple inequalities can be used to represent the minimum and maximum amount of money that can be spent on different categories such as groceries, rent, and entertainment. They can also be used in engineering and economics to model systems with multiple variables and constraints.
