If you are trying to estimate x where f(x) = g(x) using a table of values, and
all the values for f(x) - g(x) are
negative, what does this imply?

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

it will cost dollar $540

the living room is 3 which means if we divide 325/3 then we get $108

therefore if 1part of the living room cost $108 and 3 costed $325

then total 5part of the room will cost 5*108 which gives $540

a. 12.5 kg

step-by-step explanation:

f = ma

so

m = f/a = (2500 n)/(200 m/s²) = 12.5 kg

1 n = 1 kg·m/s²
