Step-by-step explanation:

Hello There!

to solve we want to isolate the variable (x) by using inverse operations

-4x-8>-20

to get rid of the -8 we add 8 to each side

-8+8 cancels out

-20+8=-12

now we have -4x>-12

now we want to get rid of the -4, to do so we divide each side by -4

-4x/-4=x

-12/-4=3

NOTE: when we divide each side by a negative number we flip the inequality sign so instead of facing the variable (x) it would face the constant

so the answer would be

x<3

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

i'm pretty sure it would take 20 hours because it's half the men so you multiply the number of hours it takes by 2
