An investigation is currently worth 1.2 x10^7 dollars twenty years ago the investment was worth 9.6x10^5 dollars how many times greater in the value of the investment today than the value of the investment twenty years ago a. 0.125 b. 12.5 c. 125 d. 12,500

As given,

Current value = dollars

Twenty years ago value was = dollars

suppose x times the investment has increased, so,

*x=

x =

this gives x = 12.5 times.

Hence, option B is the correct answer.

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)
