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
Answer:
4√7
Step-by-step explanation:
it's correct I m pretty sure but dat
1 because you replace x with 2 so, (2)squared -5x2 + 7 = 4 - 10 + 7 = 1
