Near the end of a star's life , star will eject gas, forming a plane tary nebula . The Ring Nebula is an example of a planetary nebula The volume V (in cubic kilometers ) of this nebula can be modeled by V = (9.01 * 10 ^ - 6) * t ^ 1 is the age (in years ) of the nebula . Write the inverse model that gives the age of the nebula as a function of its volume . Then , determine the approximate age of the Ring Nebula given that its volume is about 1.5x 10 cubic kilometers

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)

-2

7 - 9 = -2

reversed:

-2 + 9 = 7

i think it is 70

step-by-step explanation:

all group life insurance is term insurance. actually it is annual renewable term and it is rated on the average age and claims experience of the entire group, which is called "experience rating." remember, this type of insurance has a 31-day grace period and is convertible to whole life upon leaving employment. a contributory group plan requires that both the employer and the employees pay part of the premium. at least 75% of those eligible must participate, so the group is sure to get most of the healthy employees as well as those that are sick.
