Dependent variable is dependent on the independent variable
independent variable influences the dependentvariable
number of months influences the hcost
independent=number of months
dependent=cost
for the cost for 4 or 2 months, just start at months=2 or 4 and go up till you hit the line
equation=y=mx+b
m=slope
b=yintercept or starting point
solid line
initial fee=20
see attachment, black lines are what they are
2 months=$80
4months=140
rate is $30 per month
equation is c=30m+20
dashed line
intial fee=50
attachment, blue is dashed points
2months=$70
4months=$90
rate is $10 per month
equation is y=10x+50
Sine, Cosine, Tangent, Cosecant (opposite of Sine), Secant (opposite of Cosine), and Cotangent (opposite of Tangent)
What does mean?
work it out in your head.
Answer:
Basically what you want to do is get x by itself by adding -14 to the other side
Then you get 3x = 60
Next you divide 60 by 3 and get 20
<h2>X = 20</h2>
MHL is an obtuse angle, 160>90
HPK is an acute angle, 20<90
LHK is an acute angle, it looks smaller than 90
MHJ is an acute angle, it looks smaller than 90
JL intersects MK
