0
Step-by-step explanation:
-20.5 is the same as -20.5
, since anything to the zero power is equal to 1.
Answer:
c
Step-by-step explanation:
Answer:

Step-by-step explanation:
Let x be the distance driven, d-distance and C our constant.
Our information can be presented as:

#Subtracting equation 2 from 1:

Hence the fixed cost per mile driven,
is $0.20
To find the constant,
we substitute
in any of the equations:

Now, substituting our values in the linear equation:
#y=cost of driving, x=distance driven
Hence the linear equation for the cost of driving is y+0.2x+284
I believe the measurement of AB is 30 degrees
Answer:
-3 constant , x variable +7 constant
