That could take a long time!
There is the whole family of a/10 - b/10 where a = b + 3
Eg 4/10 - 1/10, 5/10 - 2/10, 6/10 - 3/10 etc

Or you could get sneaky with 5/6 - 8/15, 27/40 - 3/8, 1/2 - 1/5, etc

There are an infinite number of fraction pairs with a difference of 3/10

Start with a multiple of 10 on the denominator eg 50 =5 x 10
Now pick numerators with a difference of 5 x 3 eg 11 and 26
This will give you 26/50 - 11/50 = 13/25 - 11/50 = 3/10

You will get more fun problems if you avoid relatively prime fractions so they will simplify
Eg denominator 60, numerator difference 18.
59/60 - 41/60 = 3/10 is not nearly as much fun as 45/60 - 27/60 = 3/4 - 9/20 = 3/10

Definition of Variable and Constant with examples!<br>Spam free answers required!​
ra1l [238]

Answer:

\large\boxed{\boxed{\boxed{\mathfrak{variable}}}}

Variable is a symbol that represents a quantity in a mathematical expression, as used in many sciences. Variable (research), a logical set of attributes. Variable star, a type of astronomical star.

\large\boxed{\boxed{\boxed{\mathfrak{constant}}}}

A constant, sometimes also called a "mathematical constant," is any well-defined real number which is significantly interesting in some way. A function, equation, etc., is said to "be constant" (or be a constant function) if it always assumes the same value independent of how its parameters are varied.

5. Given (x + 1) and (x-3) are factors of P(x) = x4-5x³-7x² + cx + d. Determine the values
Iteru [2.4K]

By concepts of polynomials and systems of linear equations, the constants c and d of the expression p(x) = x⁴ - 5 · x³ - 7 · x² + c · x + d are 29 and 30.

<h3>How to determine the missing coefficients of a quartic equation</h3>

A value x is a root of a polynomial if and only if p(x) = 0. We must replace the given equation with the given roots and solve the resulting system of <em>linear</em> equations:

(- 1)⁴ - 5 · (- 1)³ - 7 · (- 1)² + (- 1) · c + d = 0    

- c + d = 1      (1)

3⁴ - 5 · 3³ - 7 · 3² + 3 · c + d = 0    

3 · c + d = 117       (2)

The solution of this system is c = 29 and d = 30.

By concepts of polynomials and systems of linear equations, the constants c and d of the expression p(x) = x⁴ - 5 · x³ - 7 · x² + c · x + d are 29 and 30.

all you have to do is see whether both variables of each point meet both contraints:

for a) 1<3 and 2>1 is true so a is a solution to the system
