Answer:
Simplest function is f(x) = 2x - 1
Step-by-step explanation:
When a function has a zero, simply put, that point is where the graph goes through the x-axis. At this point, the y value is 0.
If a function has a 0 of 1/2, that translates to x = 1/2 and also (1/2, 0). That means that y = 0 when x = 1/2.
If x = 1/2 and is a zero, then x - 1/2 = 0 and 2x - 1 = 0 (notice that y = 0 here and solving for x would get you right back to x = 1/2).
The simplest function with a zero of 1/2 is
f(x) = 2x - 1
You know it is true that the zero is 1/2 for two reasons. First one is to set the right side equal to 0 and solve for x.
The second one is to graph the line y = 2x - 1 and see that it goes through the x axis at 1/2 where y = 0.

<span>Distance = Square Root ( (X difference)^2 + (Y difference)^2 )</span>
So we have
Square Root (-5 -3)^2 + (-2 -13)^2 =
Square Root -8^2 + -15^2 =
Square Root (64 + 225)
=17

Answer:
C
Step-by-step explanation:
First, determine the amount it takes- in this case, it's 82.5 miles. To find out the gallons he'll need to use, divide it by 30 to get 2.75 gallons. 3.05 times 2.75 is 8.3875, rounding to $8.39.
