Answer:
The answer is:

which agrees with the last answer option (D) in the list.
Step-by-step explanation:
In order to add rational expressions, we need to express them with the same denominator. Therefore we examine what factors there are in the first denominator, which happens to be a difference of squares which is readily factored out as:

the second denominator consists of only one of these factors:
, then in order to express both rational expressions with the same common denominator, we multiply numerator and denominator of the second fraction by the factor: 
Then we get two expressions that can be easily added as shown below:

Answer:
y=2x+4 so C
Step-by-step explanation:
Answer:
b=8
Step-by-step explanation:
b²+15²=17²
b²+225=289
b²=289-225
b²=64
b= 8

Answer:
( -1,-2)
Step-by-step explanation:
x + y = -3
x - y = 1
Add the two equations together to eliminate y
x + y = -3
x - y = 1
------------------
2x = -2
Divide by 2
2x/2 = -2/2
x = -1
Now find y
x+y =-3
-1 +y = -3
-1+1 +y = -3+1
y = -2
( -1,-2)
First, find the slope 11-5/5-2 =6/3
Then, you plug in (2,5) and 6/3 and then you get your answer!
Answer: y-5= 6/3(x-2)
