the water at the dock at 4pm was 10 inches below sea level. the water continued to rise an extra 5 inches after each passing hour.
If it is perpendicular then the slope of it will be:
y = 1/3 x + b
-1 = (1/3)(3) + b
-1 = 1 + b
b = -2
The equation is:
Answer:
2 x 30 = 60 cents
3 x 25 = 75 cents
60 + 75 = 135 cents or 1 dollar 35 cents
Hope this helps
Step-by-step explanation:
x=3 is your answer. This is because it only crosses the x-axis and this occurs at positive 3. y=3 on the other hand would be a horizontal line that only touches positive 3 on the y-axis.
