To subtract means to take away a number from another number to find the difference between them. We model subtracting a positive integer on the number line by moving left. We also model the addition of a negative integer on the number line by moving left. When we compare the number line models for the equations 15 – 5 = 10 and 15 + (-5) = 10, we see that they look the same. 5 and -5 are additive inverses. This shows that subtracting an integer is the same as adding its additive inverse.

step-by-step explanation:

x^2 -12x + 36 + y^2 = 36

x^2 + y^2 = 12x

r^2 = 12rcos(theta)

r = 12 cos(theta)

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
