Therefore, the solution for the given rational equation is .$16:(5 CHEMISTRY How many milliliters of a 20% acid solution must be added to 40 milliliters of a 75% acid solution to create a 30% acid ...

To do this set the two elements of in the utility function equal to each other so there is no extra X or Y being consumed that gives no extra utility. 2X=3Y rearrange Y=2X/3 - so ray from original which goes through all the corners of the L has to have the slope 2/3. The indifference curve is for when utility is 6.
According to the given condition, Three years hence, Age of Aftab = x + 3 Age of his daughter = y + 3 According to the given condition, Thus, the given conditions can be algebraically represented as: x - 7y = -42 x - 3y = 6 Three solutions of this equation can be written in a table as follows:

5. In general, which of the following descriptive summary measures cannot be easily approximated from a boxplot? a) The variance. b) 30. True or False: If the distribution of a data set were perfectly symmetrical, the distance from Q1 to the median would always equal the distance from Q3 to the...
The solution set of the system is the set of m-tupels which each satisfy every equation of the system. 1.2.3 Remark Note that any solution of a system with nequations and mvariables is a list with mentries (independent of the number of equations n)!!
Solve the following logarithmic equation. Express irrational solutions in exact form. log. 3(5x)=2. Rewrite the given equation without logarithms. Do not solve for x. (Do not simplify. Use integers or fractions for any numbers in the equation.) Select the correct choice below and, if necessary, fill in the answer box to complete choice. A.
Dec 21, 2020 · [2b.] $$0x=0$$, one solution for each number: $$x$$ In each case the linear operator is a $$1\times 1$$ matrix. In the first case, the linear operator is invertible. In the other two cases it is not. In the first case, the solution set is a point on the number line, in the third case the solution set is the whole number line.
Solve the Following Inequation and Represent the Solution Set on the Number Line 2x – 5 <= 5x + 4 < 11, Where X ∈ I Concept: Equation of a Line.
May 24, 2014 · The number of solutions with x1<=10 is the total number of solutions minus the solutions where x1>=11. Then again it can be solved in a similar matter. This leads to 25C4-14C4 = 12650 - 1001 = 11649 solutions. Since my head started spinning with d). I googled the answer for d) 'The solution could also be found using combinations with repetitions,

• The equations will tell you what the slopes of the lines are, just look at them. If they are different, then the equations have a unique solution.. For a very basic example: (0,0) satisfies the linear system of equations given by y=x and y=-2x By substituting in x=0 into both equations, the following is...
• The above solution set is: {2, 3}. Solutions Everywhere! Some equations are true for all allowed values and are then called Identities. That was interesting ... we thought we had found a solution, but when we looked back at the question we found it wasn't allowed! This gives us a moral lesson
• The given equation is: $$\displaystyle 3 x + 7 (x + 1) + 2 = 9 - 9 x$$ To determine whether the equation is an identity, a conditional equation or a contradiction, solve for the variable {eq}x {/eq}.
• How To: Given a rational equation, solve it. Factor all denominators in the equation. Find and exclude values that set each denominator equal to zero. Find the LCD. Multiply the whole equation by the LCD. If the LCD is correct, there will be no denominators left. Solve the remaining equation.
• The solution set of the equation |x|=5 is {_____}.

However, if we allow A = 0 we get the solution y = 25 to the diﬀerential equation, which would be the solution to the initial value problem if we were to require y(0) = 25. Thus, y = 25+ Ae−2t describes all solutions to the diﬀerential equation ˙y = 2(25− y), and all solutions to the associated initial value problems.

If solving a linear equation leads to a true statement like 0 = 0, then the equation is an identity and the solution set consists of all real numbers, R. If solving a linear equation leads to a false statement like 0 = 5, then the equation is a contradiction and there is no solution, ∅.
A system of equations refers to a number of equations with an equal number of variables. This is the standard form for writing equations when they are part of a system of equations: the variables go in order In the following pages we will look at algebraic methods for finding this solution, if it exists.for example the (4) (4) if we add that numbers the result is 8, 8 is the middle number of the equation. The (4) (4) is the answer. and transpose the sign from positive to negative. Or if it is negative transpose to positive. so the answer is: x=-4 x=-4

We saw the following example in the Introduction to this chapter. It involves a derivative It is the same concept when solving differential equations - find general solution first, then substitute given numbers to find particular solutions. Here is the graph of the particular solution we just found

Jun 30, 2011 · Description of Solution Sets . The prior subsection has many descriptions of solution sets. They all fit a pattern. They have a vector that is a particular solution of the system added to an unrestricted combination of some other vectors. The solution set from Example 2.13 illustrates.
