intro

Equations are used to represent the relationships between variables. In , the variables are x & y and the following observations are true for the given equation:

Given that:

the square of x

So, means that: the y is 1 less than the square of x

From the attached table, we have:

This means that:

Also, we have:

This means that:

Collect like terms

Take square roots

Hence, the values of a and b are 3 and 0, respectively.

The graph options are not made available. So, I will plot the graph of .

the best buy, is the 4- kilogram bag of lollipops for $18.40.

step-by-step explanation:

i found my answer by dividing the cost of each bag by their respective weights.

14.88 divided by 2 = 7.44

17.29 divided by 3 = 5.77

18.4 divided by 4 = 4.6

24.4 divided by 5 = 4.88

by this, i found that the 4 kilo bag is the best buy.
