Answer:

The slope is -4 and the y-intercept is 8.

Step-by-step explanation:

y+4x=8

y=8-4x

5x - 47< 3(12x - 108) – 2​
TEA [102]

Answer:

9 < x

Step-by-step explanation:

5x - 47< 3(12x - 108) – 2​

Distribute

5x - 47< 36x - 324 – 2​

Combine like terms

5x - 47< 36x-326

Subtract 5x from each side

5x-5x - 47< 36x-5x-326

- 47< 31x-326

Add 326 to each side

326 - 47< 31x-326+326

279 < 31x

Divide by 31 on each side

279/31 < 31x/31

9 < x

Artemon [7]
A box (cube) has all equal edges or sides (s), thus the volume (v) of the cube is:
v =  {s}^{3} \\ 27 \:  {in}^{3} =  {s}^{3}  \\  \sqrt{( {s}^{3}) } =  \sqrt{( {27in}^3)}  \\ s = 3 \: in
So since each side or edge around is 3 in, then the length around the square bottom of the box = 4×3 = 12 in
