In this case the temperature depends on the hour. So temperature is your X and hour is your Y variable. When h=0, x=0. So the 21*C is you x=0 or y-int point.
If we are trying to match the equation for a line of y=mx+b, 21*C=b.
Our rate of change is -4*C/h, which is our m variable.
So y=(-4)x+(21)
OR in this case, t=-4h+21.
Answer D.
Answer:
B
Step-by-step explanation:
add his cash,car that's paid off,and his savings.
=6,015.52
then you add his credit card debt and motorcycle debt together
=1,797.98
subtract the two.
6,015.52
-
1,797.98
=
his net worth total is 4,217.54
This phrase can be written as 20 + f.
So, 20 + f is the answer.
Base on your question were the are proofs that is given are this are: CB bisects BD, DE bisects EC, CB=DE. So answer your question you must understand first your given statements and realize that CBD and DEC are both right triangles because they are a perpendicular segment so i conclude that the answer should be CBD=DEC because they are both right angles
Answer:
10
Step-by-step explanation:
Add all of the numbers up and divide by the amount of numbers there are. You subtract for the negatives.
