3500 miles divided by 175 Miles Per Hour. 3500/175=20 Hours.
Dy/dx=1/2, 1/2, 1/2 etc
So this is a linear equation of the form y=mx+b where m=dy/dx=1/2 so
y=x/2 +b, now we can use any point to solve for the y-intercept, "b", I'll use (7,0)
0=7/2 +b
b=-7/2 so
y=x/2-7/2
y=(x-7)/2
13 2/3
Hope this helped :)
Answer:
1/221=0.0045
Step-by-step explanation:
<u>a = b + c/d</u>
Subtract 'b' from each side: a - b = c/d
Multiply each side by 'd' : <em>d (a - b) = c
</em>
