Suppose we choose

and

. Then

Now suppose we choose

such that

where we pick the solution for this system such that

. Then we find

Note that you can always find a solution to the system above that satisfies

as long as

. What this means is that you can always find the value of

as a (constant) function of

.
Answer:
The answer is Slope of CD = -5/4.
Step-by-step explanation:
The question is missing important information like the values for which the slope has to be find
Points A(0,-1), B(5,3), C(2,3), D(6,-2) is missing in the question
Formula for slope:
Slope =
/
C(2,3), is 
D(6,-2) is
. for slope of CD.
Putting values in the formula.
Slope =
/ 
Slope = -5/4
This formula can be used for for finding slope for values of A and B similarly.
Answer:
I think is is a bit b
Step-by-step explanation:
a or b
Sum of geometric sequence
for the sum where the initial value is a₁ and the common ratio is r and the term is n

common ratio is -3
-5 times -3 is 15, -15 times -3=-45 etc
first term is -5
and we want the 8th term





the sum is 8200
Take out a common factor between 3x and kx. That means use the distributive law to get what you normally would start with.
x(k + 3) = 4
Now divide by k + 3
x = 4/(k + 3)
That's as much as you can do with this question.
