How can you calculate the arbitrary constant in the solution to an antiderivative?
You can't, unless it's an initial value problem. If f(x) is an antiderivative to g(x), then so is f(x) + c, for any c at all.
What is the ordered pair that is the solution to these equations 2x - 3y equals 7 and -3y plus y equals 7?
2x - 3y = 7 -37 + y = 7 The second equation simplifies to -2y = 7 so that y = -7/2 Substituting this value for y in the first equation gives 2x - 3*(-7/2) = 7 2x + 21/2 = 7 or 4x + 21 = 14 so that 4x = -7 and so x = -7/4 So the solution to the given question is (x, y) = (-7/4, -7/2)
What is the discriminant and how is it used to solve equations using the quadratic formula?
It is not to solve so much as to see the number of solutions and whether there is a real solution to the equation. b2 - 4(a)(c) A positive answer = two real solutions. A negative answer = no real solution ( complex solution i ) If zero as the answer there is one real solution.
What is the solution for 15 equals 5x?
5x = 15 so x = 15/5 = 3
What is the solution of this linear system 3x plus 5y equals -1 2x-5y equals 16?
3x + 5y = -1 2x - 5y = 16 Add the two equations: 5x = 15 or x = 3 Substitute for x in the first equation: 3*3 + 5y = -1 15 + 5y = -1 5y = -10 so y = -10/5 = -2 The solution is (x, y) = (3, -2)

How can graphs be used to estimate the solution for a system of linear equations?
Graphs can be used in the following way to estimate the solution of a system of liner equations. After you graph however many equations you have, the point of intersection will be your solution. However, reading the exact solution on a graph may be tricky, so that's why other methods (substitution and elimination) are preferred.
What concentration indicates a basic solution?
I think you mean the pH value, it so, a basic solution has any value exceeding 7.
In algebra is it possible to have no solution?
It is definatly possible to have a no solution answer in algebra. The most common time a no solution answer will occur is in an absolute value problem. Absolute value problems cannot equal zero so if you have the problem: the absolute value of 2m - 3 = -14 the answer would be so solution because it cannot equal a negative number
Which of the following cannot be in the solution set of 1?
Nothing that follows can be in the solution set of 1 so all of it cannot.

Which one of the following demonstrates the use of the CAIV philosophy?
Designing a system with requirements that maximize performance while minimizing cost and risk would demonstrate the use of the CAIV (Cost As an Independent Variable) philosophy.
If you have to make exactly five dollars using exactly 100 coins and the only coins you can use are half dollars dimes and pennies how many of each coin do you have?
The data of the problem lead to the following system of two equations: x + 10y + 50z = 500 x + y + z = 100 We subtract the second equation from the first equation: 9y + 49z = 400 For z = 1, y = 39, x = 60 For z = 2 the system has no solution For z = 3 the system has no solution For z = 4 the system has no solution For z = 5 the system has no solution For z = 6 the system has no solution For z = 7 the system has no solution For z = 8 the system has no solution For z = 9 and higher, y cannot be a positive integer, so we can ignore these. So the only solution would be 1 half dollar, 39 dimes and 60 pennies. That's where I end up after getting 770 Math and 650 Verbal on the SAT and 800 on the Math II achievement test (previous names of the SAT tests). *Sob...*
Which has higher pH value 1M HCl or 1 M NaOH solution?
THE PH VALUE ACIDIC SOLUTION VARIOUS FROM 0-6.9, WHILE THE BASIC SOLUTION VARIOUS FROM 7.1-1.4. THUS ,OUT OF HCL AND NaOH WILL HIGHER PH VALUE
What is a solution that contains an excess of protons?
The solution is an acid. If it is in water (supposedly meant by questioneer), the pH value is below 7.0, so it is an acid solution: more H+ than OH-.
What is the solution of 3x-5 20?
That will depend on the plus or minus value of 20 or perhaps there is an equality sign missing and so therefore it has no solution.
Solution to the following system of equations 5x2 - 2y2 equals -20 7x2 - y2 equals 152?
5x2 - 2y2 = -20 7x2 - y2 = 152 Eq1 - 2*Eq2: -9x2 = -324 so that x2 = 36 Substituting the value of x2 in Eq1: 2y2 = 200 so that y2 = 100 The four solutions are (-6, -10), (-6, 10), (6, -10) and (6,10)
