Question

The equations 2x+4y=8 and 8x+ay=32 represent the same straight line if a=​

Answer 1

Answer:

16

Step-by-step explanation:

When the coefficients of two straight lines are proportional they are called identical(same) straight lines.

Let us assume, the straight lines

ax + by + c = d

a2x + b2y + c2=d2  are identical then

a/a2=b/b2=c/c2=d/d2.

therefore we have a=2 ;a2=8 ;b=4,b2=?

b2=(8*4)/2

b2=16.
