Answer with Step-by-step explanation:
We are given the table as:
x f(x)
0 6
2 7
4 0
7 5
i.e. corresponding to different values of x we are given the values of f(x)
we have to find the value of f(0)
i.e. we have to find the value of f(x) when x=0
As we can see from the table the value of f(x) at x=0 is 6
Hence, Correct option is:
C) 6
I’m assuming you’re looking for a factored answer: 4(x+4)(x+1)
The first choice is correct. We can check it by cross multiplication. 15x18=270 also 3x90=270.
The two equations represent the different speeds (60 and 40) that two cars are traveling and the distances where they began (5 and 40). The solution represents the time(x) when they have traveled the same distance. Graphically it is the point where they intersect.
Other scenarios would be any time you are comparing two things like cost to drive two different cars or internet services.
Systems of equations help us see each situation, in this problem the time and distance a car travels then relate it to another car's distance traveled at the same times.
