Step-by-step explanation:
Its Undefined.
Reason
Slope (m) = y2 - y1/(x2-x1)
= 3-(-6)/(12-12)
=9/0
Undefined
You can clearly see this from the points. The x value has 2 different values for y... Which Makes the points not that of a function.
Answer: C ;)
Step-by-step explanation:
It would beat 144 beats per minute. 60/12 is 5 so 12*12 is 144
Answer:
y = - 10
Step-by-step explanation:
Given that y varies directly with x then the equation relating them is
y = kx ← k is the constant of variation
To find k use the condition y = 2 when x = - 4, that is
2 = - 4k ( divide both sides by - 4 )
= k, that is
k = -
y = - x ← equation of variation
When x = 20, then
y = - × 20 = - 10
To find the value of n, we need to subtract 2 from 24. 24 - 2 = 22.
So, n = 22.
