Step-by-step explanation:
A rational function as any function which can be defined by a rational fraction I in algebraic fractions such that both the numerator and the denominator are polynomials
Functions as a form of the non rational function which is usually defined as a function that can be written as the quotient of 2 polynomials with integral coefficients
This is a rational function
It would be c≤3 as in c is less than or equal to three
Answer:
33/4
Step-by-step explanation:
Let the first number be x, and the second number be y.
x - y = 4
x + y = -7
Solve for x in the first equation.
x - y = 4
x = 4 + y
Put x as (4 + y) in the second equation and solve for y.
4 + y + y = -7
4 + 2y = -7
2y = -7 - 4
2y = -11
y = -11/2
Put y as -11/2 in the first equation and solve for x.
x - y = 4
x - (-11/2) = 4
x + 11/2 = 4
x = 4 - 11/2
x = -3/2
Their product is:
-11/2 × -3/2
33/4
