The value would be 5 itself because it is in the ones place. If it were in the tens place it would be 50, if it were in the hundreds place it would be 500, and so on. Hope this helps. Let me know if you need anything else or if I can clarify anything for you, and feel free to post more questions.

Answer: Choice B) 3 years
--------------------------------------
Explanation:
The simple interest formula is
i = P*r*t
where,
i = interest
P = principal
r = interest rate in decimal form
t = time in years
In this case,
i = 840
P = 7000
r = 0.04 (move the decimal point 2 spots to the left go to from 4% to 0.04)
t = unknown; we'll leave it as t
Plug the given values above and solve for, or isolate, t
i = P*r*t
840 = 7000*0.04*t
840 = 280*t
840/280 = 280*t/280
3 = t
t = 3
It will take 3 years
Answer: y = -9x - 9
First, you need to put the two equations into slope intercept form (y=mx+b.)
1) y= -9x + 9
2) y= -10x - 9
First take the slope of #1
m = -9x
Then take the y-intercept of #2
b = -9
Now, put it into an equation.
y = -9x - 9
