Answer 2

(х+7)^-1=(-6,75+7)^-1=0,25^-1=1/0,25=4

Answer 3

To evaluate the expression (x + 7)^-1 at x = -6.75, you simply substitute the value of x into the expression and perform the calculation:

(x + 7)^-1 at x = -6.75

= (-6.75 + 7)^-1

= (0.25)^-1

Now, to find the inverse of 0.25, simply take the reciprocal:

= 1 / 0.25

= 4

So, (x + 7)^-1 at x = -6.75 is equal to 4.
