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:
D then A
Step-by-step explanation:
7:35 because 7:20 + 15 = 7:35
Answer:
The slope is -1
Step-by-step explanation:
The slope is always the number in front of the x.
Answer:
d) the slope of f(x) is greater than the slope of g(x)
Step-by-step explanation:
to find the slope of an equation, you look at its rise/run. for f(x), you can see that from one point (0, 3) to another (1, 1) it goes down 2 values (3 - 1) and over 1 value (0 + 1). because it goes down 2 values, the rise is -2, and because it moves to the side 1 value positively, the run is +1.
-2/+1 = -2. this means the slope of f(x) = -2.
finally, it says the slope of g(x) = -6, and -2 > -6. i hope this helps! :)
