1.) You have 12 toppings. You choose one topping--that leaves you with 11 toppings. You choose another--that leaves 10. 12×11×10 = 1,320.
Multiply 1,320 topping choices by 6 cheeses to get 7,920 total combinations.
2.) (Though I'm less sure of these)
CDs: 6×5×4×3×2 = 720
Cassettes: 5×4 = 20
DVDs: 8×7×6×5 = 1680
A suitable calculator can row-reduce the augmented matrix.
first number: 3
second number: 1
third number: 8
I’m learning this in class as well
Ok so basically you just need to find 2 random points so like (30,100) and (20,30)
And my question for you is do you know the equation format?
Mult

div

baseically, x is the base, and m and n are bases
you can only use this property if bases are same
baseically
multiply means add powers
divide means subtract bottom power from top
