X^-1 = 1 / x ;
( x + 1 )^-1 = 1 / ( x + 1 ) ;
Then, x^-1 - ( x + 1 )^-1 = 1 / x - 1 / ( x + 1 ) = ( x + 1 ) / [x( x + 1 )] - x / [x( x + 1 )] = ( x + 1 - x ) /[x( x + 1 )] = 1 / [x( x + 1 )];
Finally, (1 / [x( x + 1 )])-2 =[x( x + 1 )]^2 = (x^2)[( x + 1 )^2] ;
What is the question it’s not showing
What was ur bday last year and then add one day onto it. So say last year it was Tuesday then this year it would be Wednesday
Answer:
y = -3/2x + 1 1/2
Step-by-step explanation:
the slope would be -3/2 because you have to find the reciprocal and switch the sign. To find the y intercept you would plug in the points to the equation.
6 = -3/2(-3) + b
6 = 4.5 + b
1.5 = b
