X + (-4) = -2 <br> What does X repesents??? Please help
Nonamiya [84]

Answer:

x=2

Step-by-step explanation:

x+(-4) is the same as x-4

First you have to get X alone so you add 4 to both sides because when you add 4 to both sides it will take away the 4 on the x side.

x-4=-2

+4    +4

x= -2+4                or you can see this as 4-2 which is 2

x=2

A manufacturing plant earned \$80$80dollar sign, 80 per man-hour of labor when it opened. Each year, the plant earns an addition
vagabundo [1.1K]

Answer:

A(t)=80(1.05)^t

Step-by-step explanation:

The manufacturing plant earned $80 per man-hour of labor when it opened

The plant earns an additional 5% for every additional man-hour t.

This can be modeled using the function:

A(t)=P(1+r)^t

where Initial Amount Earned, P=80

Rate of Increase, r=5%=0.05

Therefore, the function that models the amount earned at any time t is:

A(t)=80(1+0.05)^t\\A(t)=80(1.05)^t
