Dunnow what the formula is for
combinations vs permutations
combos, the order does matter and you can repeat
permutations, the order doesn't matter and once you use something, you can't repeate it
what you do is
(number of choices)^(number of slots y ou have to fill)
in this case
number of choices is 3 (3 fllavors)
number of slots=2 since 2 toppings
3^2=9
9 choices
chocolate-carmael
chocolate-strawberry
chocolate-chocolate
strawberry-carmael
strawberry-chocolate
strawberry-strawberry
carmael-chocolate
carmael-strawberry
carmael-carmael
9 choices
Answer: See explanation
Step-by-step explanation:
We are informed that we should write a equation that represents the expression "Ali writes the expression "half of the sum of $9 and a number.".
Let the number be represented by x. The first equation based on the information given will be:
= 1/2(9 + x)
The second equation will be:
= (9 + x)/2
= 4.5 + 0.5x
Answer:
yes
Step-by-step explanation:
c + 3 > 5
subtract 3 from both sides: c > 2
c - 1 > 1
Add 1 to both sides: c > 2
Therefore, they are equivalent.
(x²+3x-4)(x-5)
x³-5²+3x²-15x-4x+20
x³-2x²-19x+20
Answer:
-5x+3 OR 5x-3
Step-by-step explanation:
You find the inverse by replacing the x with the y, and solving for y. Doing this actually gives you -5x+3 but in this case, the closest answer would be 5x-3.
UPDATE: -5x + 3 can be written as 3 - 5x lol
