Answer:
Unknown number, x=-4
Step-by-step explanation:
Forming the equation from the information provided above.
9=2x+17
If we solve for the unknown number, we first collect like terms together.
2x=9-17
2x=-8
Divide both sides of the equal sign by 2 the coefficient of x
x=-4
Answer:
Option C 
Step-by-step explanation:
step 1
Find the slope of AB
we have
A(-3,-1) and B(4,4)
The slope m is equal to


step 2
Find the slope of BC
we know that
If two lines are perpendicular, then the product of their slopes is equal to -1
so

we have

substitute


step 3
Find the equation of the line into slope point form

we have


substitute

Multiply by 5 both sides



Multiply by -1 both sides

The given equation x-1/x-2+x+3/x-4=2/(x-2).(4-x) is correct. the answer is proved.
According to the statement
we have given that the equation and we have to prove that the given answer is a correct answer for those equivalent equation.
So, The given expression are:

And we have to prove the answer.
So, For this


Then the equation become

Now solve it then

Now take 2 common from answer then equation become

Hence proved.
So, The given equation x-1/x-2+x+3/x-4=2/(x-2).(4-x) is correct. the answer is proved.
