Simple way to see it is to multiply the value opposite of the axis you're flipping it over by -1. For example the point (-5,7) would become (5,7) when reflected over the y-axis, because the point is moving from the left to the right. This means the triangle would be (1,3) (5,3) and (5,7) when reflected over the y-axis. For reflection over the x-axis it would be (-1,-3) (-5,-3) and (-5,-7) because each point is moving down.
Since it starts with 2 envelopes, subtract 2 from 17 to get how many and in all 3 packs.
17 - 2 = 15
Now, we divide that number by 3 to get how many are in each envelope.
15 / 3 = 5
There are 5 envelopes in each pack.
I think it’s C but I could be wrong but I don’t think I am
Answer:
34 minutes
Step-by-step explanation:
Given:
Ratio of time for which Pepperoni pizza and cheese pizza should be baked is given as:

Where
is the time for which pepperoni pizza should be baked and
is the time for which Cheese pizza should be baked.
Also, it is given that a small Cheese pizza should be baked for 12 minutes.
In other words, we are given that: 
To find:
For how long small pepperoni pizza should be baked ?
In other words,

Solution:
Let us put the value of
in the equation of the model.


Therefore, a small pepperoni pizza should be baked for <em>34 minutes</em>.
