1). linear combination (show work)

3x +2y = −4

4x − y= 13

2). graph

y= 1/2 x + 3

-3x+y=-2

Part 1) The solution of the system of equations is (2,-5)

Part 2) The solution of the system of equations is (2,4)

Step-by-step explanation:

Part 1) Linear combination

we have

-----> equation A

-----> equation B

Multiply equation B by 2 both sides

-----> equation C

Adds equation A and equation C

Find the value of y

The solution of the system of equations is (2,-5)

Part 2) By graph

-----> equation A

-----> equation B

we know that

The solution of the system of equations is the intersection point both graphs

Using a graphing tool

The intersection point is (2,4)

therefore

The solution of the system of equations is the point (2,4)

see the attached figure

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.
