Can someone teach me how to graph these linear inequalities im stuck
1. 8x+y> 1
2. x-4y< 4
3. 4x+5y-25

452,489 to the nearest thousand is 452,000

600,000,000,000, or 6e14

step-by-step explanation:

see explanation

step-by-step explanation:

a

(6r + 7) + (13 + 7r) ( remove brackets and collect like terms )

= 6r + 7 + 13 + 7r

= 13r + 20

b

remove brackets and collect like terms

13 - r - 1 + r

= 12 - r

c

remove brackets and collect like terms

= - 8 - r + 2r - 4

= - 12 + r

d

remove brackets and collect like terms

= 7r - - - 6r

[-   - = - - = - ]

= r -

that one look
