What is Factorization?
Usually, factorization or factoring means writing a number (or another mathematical object) as a product of minor or more uncomplicated objects of the same kind.
Given -x-5 is a linear expression.
For factorizing, first, make the coefficient of x positive. For this take -1 common.
⇒ -x-5 = 
Now take the greatest common divisor (gcd) of absolute values of coefficients in x+5.
⇒ gcd(1,5) = 1.
Now take gcd 1 common in the expression.
⇒ 
⇒
.
∴ The fully factorized version of -x-5 is

ANSWER

EXPLANATION
If y varies directly with x, we write the mathematical statement;

When we introduce the constant of proportionality k, then we write the equation,

If y is 2.5 when x is 5,then we have;



The equation of variation then becomes;

when x=14,
