Lily is using dark power crystals to raise an army of zombies. Each crystal can raise 9 zombies. How many crystals does Lily need to raise 6,174 zombies?

686 crystals.

Step-by-step explanation:

You can set up an algebraic equation to find the answer.

Let x represent the number of crystals Lily uses.

The question is asking how many crystals it will take to raise 6,174 zombies, when each crystal raises 9.

9x = 6174

x = 6174 / 9

x = 686

That means it will take Lily 686 dark power crystals to raise 6,174. That's a lot of dark power!

Hope this helps!

b. t=-25h+3

step-by-step explanation:

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value
