The radius of earth's orbit is approximately 15,000,000,000 meters. the radius of mercury's orbit is 5.8 × 109 meters. what is the difference of their radii?

a.4.3 × 1010

b.4.3 × 1011

c.9.2 × 109

d.9.2 × 1010

e.9.2 × 1011

15,000,000,000 = 15 × 10⁹

15 × 10⁹ - 5.8 × 10⁹ = 9.2 × 10⁹ m

C. 9.2 × 10⁹ m

because its not ur topic and its not for is for homework not that.

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)
