The point-slope formula is y-y1=m(x-x1). So you will substitute the numbers into the equation. The answer is y+5=-2/5(x+3).
Answer:

Step-by-step explanation:
we know that
The equation of a exponential growth is equal to

where
a is the initial value
r is the rate of growth
x is the time in hours
y is the value of the quantity
we have

substitute


For x=22 hours
substitute

I this the answer you are looking for would probably be 47.7%.
hope this helps!!
Since the triangle has equal sides it will carry onto it self at 120, since it can rotate 360 grades only and it has 3 sides so it will rotate in one third of 360 so 120
i hope i helped you
