Answer:
The first one is linear the rest isn't
Step-by-step explanation:
A linear function represent a straight line.
The first one shows that.
The second function look more like a tangent function which is a trig function so it isn't linear. The third one is a exponential function which is definitely not linear.
step 1
find the slope AB
A = (-3, -1) and B = (4, 4)
m=(y2-y1)/(x2-x1)------> m=(4+1)/(4+3)------> m=5/7
step 2
find the slope mBC
we know that
if two lines are perpendicular
then
the product of their slopes is equal to -1
so
mAB*mBC=-1-------> mBC=-1/mAB-----> -1/(5/7)-----> mBC=-7/5
step 3
with mBC and the point B = (4, 4) find the equation of the line BC
y-y1=m*(x-x1)-----> y-4=(-7/5)*(x-4)-----> y=-(7/5)*x+(28/5)+4---> y=-(7/5)*x+(48/5)
y=-1.4*x+9.6
therefore
the answer is
the equation of the line BC is
y=-1.4*x+9.6

Answer:
$2,982.92
Step-by-step explanation:
Assuming straight depreciation of the asset without double declining and other accounting jargon all that needs to be done is an equation like this:
17000 * (1 - 0.135)^12 = 2982.92
