Compare the doubling times found with the approximate and exact doubling time formulas. Then use the exact doubling time formula to answer the given question. A nation of 100 million people is growing at a rate of 10% per year. What will its population be in 30years? Calculate the doubling times found with the approximate and exact doubling time. The approximate doubling time is ? years and the exact doubling time is ? years ?What will its population be in 30 years? The population would be ? million people?

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)

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0
