8 is 10% of 80
Convert the percentage into a decimal:

Multiply the decimal by 80:
I can't tell what that bottom coordinate is labeled as but I am going to call it Z.
I = (-3 , -2)
E = (-3 , -3)
Q = (2 , -4)
Z = (0 , -5
To reflect acrossed y = -2 means that
I = (-3 , -2)
E = (-3 , -1)
Q = (2 , 0)
Z = (0 , 1)
All you are doing is taking the y coordinate on each of them and basically mirroring it.
Kind of like how you look into a mirror you see a reflection all your doing is changing the y values to be the opposite of what they are when you mirror them across y = -2.
I coordinate stays at (-3 , -2) because the y coordinate (x , y) is at y = -2. Y is vertical on the graph and x is horizontal.

Step-by-step explanation:
you should try to get all the angles before getting x, so it will be easier to calculate

Answer:
pounds
Step-by-step explanation:
Let x pounds of $ 0.66 per lb candies mixed with y pounds of $ 1.31 per lb candies to obtain 9 lb of $ 0.97 per lb candies,
Hence, we can write,
x + y = 9 ------- (1)
And, 0.66 of x + 1.31 of y = 0.97 of (x + y)
⇒ 66 x + 131 y = 97 (x+y)
⇒ 66 x +131 y - 97 x - 97 y = 0
⇒ -31 x + 34 y = 0 ------(2)
By solving equation (1) and (2)
We get,
and 
Hence, the quantity of 0.66 per lb candies =
pounds
