Choice B would be the correct answer. I hope that helps! :D
Answer:

Step-by-step explanation:
First, let's start with what we have. If we use
here's what we can put in:

Then we can use one of the given points to find the y-intercept. Since the only complete one is (12,10), we'll use that.

So now we have
.
Now we can use our other point with the missing y-value and solve for y.

So the missing value is 64.
Hope this helps!
Answer:
x=13
Step-by-step explanation:
We add all the numbers together, and all the variables
6x-78
We move all terms containing x to the left, and all other terms to the right
6x=78
x=78/6
which should equal 13
Remember that parentheses come first. Follow PEMDAS
Answer: 4 years
Step-by-step explanation:
Your question isn't complete but I believe that you want to calculate the number of years. This will be:
Simple Interest = PRT/100
where,
Interest = 864 - 800 = 64
Principal = 800
Rate = 2%
Therefore, 64 = 800 × 2 × T /100
Cross multiply
64 × 100 = 1600T
6400 = 1600T
T = 6400/1600
T = 4
Therefore, time will be 4 years
