Y = kx
when y= 12, x=3
12 = 3k
k = 12/3
k = 4
y = 4x
when x= 15
y = 4(15)
y = 60
Answer:
rate of change = -0.32
Step-by-step explanation:
Rate of change = slope,m
So B is halfway between 0 and 1. What's half of 1? 1/2.
A is halfway between 0 and B. What's half of 1/2? 1/4.
So A is 1/4 of 1.
Alternatively -
0 - A - B - - - 1
If each - is an eighth, A is at 2/8, or 1/4
To answer this question you must know that there is a theorem called the "Two secants angle theorem", which establishes that the measure of an angle formed when two secants intersecting outside the circle is equal to 1/2 the difference of the two intercepted arcs.
Therefore, as you can see, the correct answer is the option B): B)<span>1/2 the difference of the intercepted arcs</span>
