0.8 - 89 * (-89) * 3 is 23763.8
so if it was three four hours and he took four five of the time it will be all day for take away for 0/0
The equation of the function is f(x) = -5x + 10
<h3>How to determine the function equation?</h3>
The points are given as:
x-intercept at (2,0) and a y-intercept at (0,10)
A linear function is represented as:
y = mx + b
Where b is the y-intercept.
The y-intercept at (0,10) means that:
b = 10
So, we have:
y = mx + 10
The x-intercept at (2,0) means that:
x = 2, when y = 0
Substitute these values in y = mx + 10
0 = 2m + 10
Subtract 10 from both sides
2m = -10
Divide both sides by 2
m = -5
Substitute m = -5 in y = mx + 10
y = -5x + 10
Hence, the equation of the function is y = -5x + 10

Answer:
C
Step-by-step explanation:
The average speed can be obtained by adding the distances together and dividing by the total amount of time.
The total distance the man traveled from A to D is the addition of the distance from A to B plus the distance from B to C plus the distance from C to D. This is mathematically equal to 145 + 160 + 115 = 420 miles.
Dividing 420 miles by 6 = 70 miles per hour
