since this is way easier here are just the rest of the questions. please write them all in slope-intercept form. 11. -3x + 2y = -4 | 12. x + 3y = 9 | 13. 3x - 5y = 20 | 14. 3x - y = 1 | 15. 5x + 4y = 0| good night i hope you guys sleep well!

11. y=(3/2)x-2

12. y=x+3

13. y=(3/5)x-4

14. y=3x-1

15. y=(5/4)x

im not 100% sure on 14 but the rest of them should b right :)

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
