Answer:
9 years
Step-by-step explanation:
7 and 55/10000 which simplifies to 7 and 11/2000
y=mx+b
m=slope
b= y intercept (when x = 0
y= y value
x=x value
you already have your slope given plug in you x and y values into the equation and reverse the math, like you would do to "solve for X this time B"
you will then get you whole equation
Answer:

Step-by-step explanation:
The equation is 
Where h(x) is the height and x is the distance from where you are standing
The new distance is "1 foot farther from where you are standing" -- so this affects x, which becomes "x+1".
We simply replace x with x +1 in the equation of h(x) and simplify if possible:

THis is the new function.
Ok it forsure is not b i am pretty sre the correct answer is c
