This is my thinking;
To convert meters to kilometers, in decimals, its 0.001. So converting that into kilometers, that would be 0.057
Slope-intercept form:
y = mx + b "m" is the slope
First i would isolate the "y" in the equation.
2x + y = 4 Subtract 2x on both sides
2x - 2x + y = 4 - 2x
y = 4 - 2x or y = -2x + 4
The given line's slope is -2.
For lines to be perpendicular, their slopes have to be the opposite/negative reciprocals (flipped sign and number)
For example:
slope is 2
perpendicular line's slope is -1/2
slope is -2/3
perpendicular line's slope is 3/2
The given line's slope is -2, so the perpendicular line's slope is 1/2.
The 3rd option is your answer
You are given the masses of four planets.
Add them together, and then divide your sum by 4.
That will be the "average planet mass" for these 4 planets.
Answer:
1/3
Step-by-step explanation:
1/2 of 2/3 = 1/3
