For a long time, mathematicians weren't sure that asymmetric encryption was possible. Fortunately, cryptographers discovered the necessary mathematical innovation in the 1970s and invented public key encryption. If public key encryption was never invented, what wouldn't be possible today?

the answer is 62

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)

1 + (6 / x - 1)

step-by-step explanation:

divide using polynomial division.
