Which ordered pair is the best estimate for the solution of the system of equations? y=−34x−2y=x+6

(-0.23,5.77)

Step-by-step explanation:

The given system of equations is

We equate both equations to get:

Group similar terms to get:

Put this value into the second equation to get y

(-0.23,5.77)

all three statements are true

step-by-step explanation:

a shipping fee of 5% is charged online with every item purchased online

first let's just take each option and calculate them based on this, to see if the answers matched

keith buys a 40 dollar book

40 x 0.05 = 2

therefore there will be a two dollar fee on keith's book

40 + 2 =42

the first statement is true

a chair costs $80

80 x 0.05 = 4

80 + 4 = 84

the second statement is true

george buys a 20 dollar calculator

20 x 0.05 = 1

20 + 1 = 21

the third statements are true

all three statements are true
