Answer 1

-8<-4

Explanation:

Given expressions:

`3x-2\\4x+4`

(a)

When x = 0:

`=3(0)-2`

`=-2`

`=4(0)+4\\=4`

Answer:

-2<4

(b)

When x = -6

`=3(-6)-2\\=-18-2\\=-20`

`=4(-6)-2\\=-24-2\\=-26`

Answer:

`-20 > -26`

(c)

When x = 5:

`=3(5)-2\\=15-2\\=13`

`=4x+4\\=4(5)+4\\=20+4\\=24`

Answer:

13<24

(d)

When x = -2:

`=3(-2)-2\\=-6-2\\=-8`

`=4x+4\\=4(-2)+4\\=-8+4\\=-4`

Answer:

-8<-4
