Which number line below represents the
inequality x < -4?

answer is because 4×10=40

and 98×4= is 392

40,392

15.36 per mile

but forgot to round

i am pretty sure

if y=4x then you will substitute 4x in for y in the second equation.

8x + 4x = 18 combine like terms

12x = 18 divide by 12 on both sides

x = 18/12 or 3/2

now replace x in the first equation with 3/2 to get

y = 4 3/2

y = 6

the answer is a

(3/2,6)

hope that .
