Question

for what value of
p the equation 4+py+8= 0 and 2x+ y + 1 = 0 are inconsistent​

Answer 1

Answer:

for p≠{2,8}

Step-by-step explanation:

inconsistent statement says

us

if A1/A2≠B1/B2≠C1/C2

so

by this condition

4/2≠p/1≠8/1

so

take

two parts

2≠p

and

8≠p

so

do all

p€ R-{2,8}

or

p ≠ {2,8}

Answer 2

Answer:

p = 2

Step-by-step explanation:

pls check attachment for more clarity.

4x+py+8= 0 ....(1)

2x+ y + 1 = 0 ....(2)

Comaparing (1) with a1x + b1y + c1 = 0

therefore, a1=4, b1=p, c1=8

Again,

Comparing (2) with a2x + b2y + c2= 0

therefore, a2= 2, b2=1, c2= 1

Now,

a1/a2 = b1/b2 (for inconsistency of eq)

4/2 = p/1

2 = p/1

p=2

hence, at p=2 the equation becomes inconsistent.
