The graph would move up 2 units
Answer:

Step-by-step explanation:
Bucket's Capacity = b liters
** Jar's capacity is 8 FEWER liters than "b", so:
Jar's Capacity = b - 8
Whenever we want how many times one is larger than another, we always find the ratio of larger to smaller. Here, bucket's capacity is larger and jar's capacity is smaller than that. So, the ratio would be:

This is the correct answer, 
This is true. In order to get an obtuse triangle, one angle must be greater than 90 degrees because the definition of an obtuse triangle is an angle measuring greater than the right angle. The other angles must be less than 90 degrees because the sum of the angles must be 180 degrees.
K added to 10 gives you 4 times the value of K.
If you wanted to solve the expression:
Subtract both sides of the expression, right hand side(10+k) and left hand side(4K), by -k as you want to get rid of the variable to get simply 10 on the LHS.
10+k -k = 4k -k
If we want to subtract k from k then we get 0, and if we want to subtract k from 4k we get 3k. For the sake of simplicity think of k as an object saying if I subtract object A from object A I get zero, and so forth.
We are left with the expression:
10 = 3k
We divide both sides by 3 as to get rid of it from the RHS.
We get a solution 10/3 = k
