Given the system of equations, what is the value of the y-determinant?
3x + y - 10 = 0
4x - y - 4 = 0

a. -28
b. -14

 The correct option is (A) -28.

Step-by-step explanation:  The given system of linear equations is as follows :

We are to find the y-determinant for the above system of equations.

The given system can be written as :

Therefore, the y-determinant of the system will be

Thus, the required value of the y-determinant is -28.

Option (A) is CORRECT.

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.

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value
