Question

The solution of the equation ax +b = 0 (a) a/b (b) -b (c) - b/a (d) b/a​

Answer 1

Step-by-step explanation:

As per diagram l∣∣m and n transversal.

We know that vertically opposite angles are equal

a=110

o

----(1)

d=85

o

----(2)

We also know that corresponding angles are equal.

a=b

d=c

=>a=b=110

o

[ from (1)]

=>d=c=85

o

[ from (2)]

Answer 2

Answer:

option c

$\frac{ - b}{a}$

Step-by-step explanation:

When a ≠ 0 the equation has one solution x = -b / a.
