A quadratic equation is a polynomial equation in which a single variable appears in a 2nd-degree term, and all other terms are 1st degree or less. A quadratic inequality is a quadratic equation in which the equal sign has been replaced by an inequality symbol.

The relation of selection A would not be a quadratic equation if the relation symbol were an equal sign, hence it is not a quadratic inequality. The best choice is

... A. y ≤ y² + x²

A typical high school student consumes 67.5 pounds of sugar per year. As part of a new nutrition plan, each member of the track
tino4ka555 [31]

Answer:

54 Pounds

Step-by-step explanation:

We know that they start off with 67.5 pounds of sugar and they need to reduce it by 20%. We also know from the problem that we want to know the MAXIMUM amount of sugar consumed by each track member.

The typical high school student consumes about 67.5 pounds of sugar per year. That is our first piece of the problem

67.5

We now know that 20% of it needs to be reduced. This means that we can multiply it by 0.8 because that is 20% less than 100% of the sugar.

67.5 x 0.8

This leads the answer to be 54 Pounds

Hope this helped :D

What is the surface area of the figure 8" 8" 12"
fgiga [73]
First, find the surface area of the bigger sides (there are 4 of them so what you get for one you will multiply by 4)

12 x 8 = 96

96 x 4 = 384

Then find the surface area of the smaller sides ( there are two small sides so multiply your answer by two)

8 x 8 = 64

64 x 2 =128

Then add both together 

128 +384 =  512

Hope this helps :)
