Answer:
k=6
Step-by-step explanation:
As stated, x=2/3, so you need to eval in the whole expression given

which becomes the following>

Solving for K gives>


So the way to calculate the slope from a line on a grid, we know that:

If we take the line RC, we count that the number of units that it rises is 3 units. However, it does not go to the right or to the left, therefore, it does not 'run' at all. It will be 0. So when we put this into a fraction:

we see that this answer comes out undefined. This is because there is a 0 in the denominator - so the slope for RC is undefined.
When we look at the line SC, we see that the units that it rises is -1 units (essentially it went down 1 unit), and we see that the number of units it 'ran' is 5 units. So let's put that into a fraction:

and we see that the slope for SC is

.
Step-by-step explanation:
1/2 - 1/6 = 3/6 - 1/6 = 2/6

Answer:
Recursive
Explicit
Step-by-step explanation:
An arithmetic sequence an be represented by a recursive rule which gives the first term and defines the nth term by relating it to the previous term, or by an explicit rule which defines the nth term as a function of n.
The recursive rule is that we have the initial term. To find the subsequent term, we will take that <em>previous term</em> and add it to our common difference.
Hence, we are <em>relating the previous terms</em> to define the nth term.
For the explicit rule, we simply have a function of n. To find the nth term, we can substitute our desired term n for n and evaluate.
Divide 45 by 9. This leaves you with 5 in the denominator of your fraction. Next, cancel out the x^5 factors completely. They disappear. Next, divide y^16 by y^4. You'll get y^12. The first answer is the correct one.
