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:
Is here a pic that goes with it?
Step-by-step explanation:
Write that as 7x. Writing it as x7 could lead to confusion. 7*x would be OK.
Answer:
Sure why not.
Step-by-step explanation:
Answer:
y=-5x-2
Step-by-step explanation:
y=mx+b
where m is the slope
y=-5x+b
to solve for b, which is the y intercept, plug in (1,-7)
-7=-5(1)+b
-7=-5+b
-2=b
y=-5x-2
