Answer:
The commutative property
Step-by-step explanation:
a math rule that says that the order in which we multiply numbers does not change the product.
It starts out being worth $100,000 (One hundred thousand dollars). Every year it depreciates by 5% (0.05). What is the value after two years? We can find this by multiplying.
100,000 * 0.05 = 5,000
100,000 - 5,000 = 95,000
95,000 * 0.05 = 4,750
95,000 - 4,750 = 90,250
The machine, after two years, will be worth $90,250.
Don't be shy about using actual parentheses and commas.
Line through (1,8) perpendicular to

The perpendicular family is gotten by swapping the coefficients on x and y, negating exactly one of them. The constant is given directly by the point we're through:

Let's clear the fractions by multiplying both sides by 20.
