The distance from mercury to the sun is 28.5 million miles. the distance from neptune from the sun is 2.8 billion miles. express the distance between mercury and neptune in scientific notation. explain how you came up with the answer.

ANSWER

EXPLANATION

The distance from Mercury to the sun is 28.5 million miles.

The distance of Neptune from the sun is 2.8 billion miles.

We know that,

1 billion=1000 million.

Therefore,

2.8 billion = 2800 million

The distance between Mercury and Neptune is

2800-28.5 million miles.

=2771.5 million miles

We rewrite this in scientific notation as,

or

answer: x

step-by-step explanation:

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)
