S1 : Logarithm of a number x is defined for all negative values of x. S2 : Logarithm of 1 to the base x (where x>1) = 0
S1 is true, S2 is false
.
We are given the equation x+2y=3
Statement 1: The degree of the equation is one.
Statement 2 : It is a linear equation in two variable.
If speed of boat in still water is x km/h and speed of stream is y kmh .
S1 : upstream speed of boat is (x-y) kmh
S2 : downstream speed is (x+y) kmh
The solution for the equations c1x + b1y + a1 = 0 and c2x + b2y + a2 = 0 is
S1 :x = (b1a2−b2a1)(c1b2−c2b1)
S2 : y =(c1a2−c2a1)(a1b2−a2b1)
S1 : 13231400 is a non terminating decimal. S2 : A number pq where p and q are co-primes is terminating if q is of the form 2n.3m where n and m are non-negative integers.
