Answer:
The Function rule for line is:
Option A is correct option.
Step-by-step explanation:
Find a function rule for the line that passes through the origin (0,0) and the point (5, - 13)
The function rule is of form:
where m is slope and b is y-intercept
Finding slope:
The formula used to find slope is:
We have
Putting values and finding slope
Finding y-intercept
We will use point(0,0) to find y-intercept
So, y-intercept is 0
The Function rule for line having slope m=-13/5 and y-intercept b=0:
So, The Function rule for line is:
Option A is correct option.
PART A. Notice that we have 
as a common factor in all the terms, so lets factor that out:
Now we need can factor
:
We can conclude that the complete factorization of is .
PART 2. Here we just have a quadratic expression of the form
. To factor it, we are going to find <span>two numbers that will multiply to be equal the </span>c<span>, and will also add up to equal </span><span>b. Those numbers are 2 and 2:
</span>
Since both factors are equal, we can factor the expression even more:
We can conclude that the complete factorization of
is 
.
PART C. Here we have a difference of squares. Notice that 4, can be written as
, so we can rewrite our expression:
Now we can factor our difference of squares like follows:
We can conclude that the complete factorization of
is 
Now we need can factor
We can conclude that the complete factorization of
PART 2. Here we just have a quadratic expression of the form
</span>
Since both factors are equal, we can factor the expression even more:
We can conclude that the complete factorization of
PART C. Here we have a difference of squares. Notice that 4, can be written as
Now we can factor our difference of squares like follows:
We can conclude that the complete factorization of
Answer:
D
Step-by-step explanation:
first of all we need to solve the inequalities
(-∞,1] or ]-∞,1]
the second inequality is
[2,∞) or [2,∞[
so the answer is D
