Question

-5 What is the sign of a. () when a = 0 and b < 0? b Sos I need help

Answer 1

$\qquad\qquad\huge\underline{\boxed{\sf Answer}}$

The sign of a will be negative ~

let the value of be be ' -x ' , -x is a negative number (b = -x < 0)

$\qquad \sf \dashrightarrow \: a \times \frac{ - b}{b}$

$\qquad \sf \dashrightarrow \: a \times \frac{ - ( - x)}{ - x}$

$\qquad \sf \dashrightarrow \: a \times \frac{ x}{ - x}$

$\qquad \sf \dashrightarrow \: a \times \frac{ - x}{ x}$

$\qquad \sf \dashrightarrow \:a \times - 1$

$\qquad \sf \dashrightarrow \:- a$

Therefore, the term a, has a negative sign unless it's value is substituted, I.e -a = 0 ( having no sign )
