Sin(arcsin^-1(x))=x for -1< x< 1 true or false?

answer : true

Proof:

Lets assume

When we move sin^-1 to the other side it becomes sin

so x= sin(y)

Now we replace it on the left hand side

= x (Right hand side)

Hence proved,

if he has no friends he cant give them out to his friends

step-by-step explanation:

no friends = cant give anything out

correct answer is infinitely many solutions

step-by-step explanation:

2(2x + 3) = -4 + 2(2x + 5)

solving the above equation:

4x + 6 = -4 +4x +10

combining like terms

4x -4x = -4+10-6

0=0

since both sides are 0=0, we end up into true statement it means it has infinite many solutions.

so correct answer is infinitely many solutions
