-4y = 8x
Divide both sides by -4
y = -2x
This is in the form of y = kx, where k is the constant of variation.
y = kx is the direct
That means, k = -2.
The constant of variation is B. -2.
28,
70 + 35 = 105, then divide by 3,000 which equals 28.57142857143, but you want a full human so you round down to 28

It is non recurring number
Hope it helps you
The equation that relates the time, t, it takes to travel a given distance, d is d = rt
<h3>What is Speed?</h3>
This is a scalar quantity and can be defined as the magnitude of the rate of change of its position with time.
d = rt
where d is distance, r is speed or rate, t is time.
We can calculate the time by dividing the distance with the rate (speed).
t = d/r
This is why it was chosen as the most appropriate choice.
