Step-by-step explanation:
1. Not a function
2. Not a Function
3. Function
Do you know the equation to use
X - 8 = 12, add 8 to 12. The answer is 20.
To answer the question above, determine the velocity of the car at time zero. To do such, determine the increase in velocity every hour (acceleration).
a = (62 - 53) / (6 -3) = 3 km/ h^2
Calculate for the initial velocity (v) by using either of the velocities paired with the corresponding time,
v = 53 km/h - (3 km/h^2) x 3 h = 44 km/h
The equation is <em>y = 44 + 3x</em>. Where x is the time in hours, y is the velocity in km/h.
Cross multiply the original proportion
5x = 2y Divide by 2
5x/2 = y Now divide by 5
x/2 = y/ 5
So the answer is y/5
