I don’t really know what you mean here but i guess you mean f(x)=2x+3=0
In that case:
F(x)=2x+3=0
Subtract 3 from both sides:
F(x)=2x=-3
Divide both sides by 2:
F(x)=x=-3/2.
His percent error was by .2 of a second, so we can do
to get our answer. After dividing, you should have got around .0869. You can convert this to a decimal by moving the decimal spot 2 places to the right to get 8%.
8% is your answer.
I'm pretty positive that the correct answer is B :)

1 = C
2 = D
3 = C
1.) the first notable point on the graph is y = 60km, X = 2 hours. This is 30km/hr
2.) “y=Mx+B” m is slope which is given (-3). B is the y value when x = 0 (+5)
3.) the function goes from negative to positive therefore it is defined and positive.
