<h3>
Answer:</h3>
B) 7x - 1
<h3>
Step-by-step explanation:</h3>
In this question, you're going to solve by adding both f(x) and g(x) together.
You're finding (f+g)(x), meaning that you will be adding both of the equations to get your answer.
What (f+g)(x) looks like:
(5x - 2 + 2x + 1)(x)
What you would do is solve to get your answer. You're going to be combining like-terms and adding.
When you're done solving, you should get 7x - 1
This means that B) 7x - 1 would be the correct answer.

Step-by-step explanation:
The domain of f(x) is all values of x for which f(x) is defined.
For f(x) to be defined, the expression under the radical must be non-negative.
Therefore, the domain is x ≥ 0, or in interval notation, [0, ∞).
In this question, the weight is going with a pattern of
2 ; 4; 6; 8; 10
0.8 ; 1.4; 2.0; 2.6; 3.2
If you look at it closely, it is clear that the difference for each of them is 2 weeks and 0.6 pounds.
Because the question is asking for initial value, then you need to subtract the first number with the pattern. it would be: 0.8 pound- 0.6 pound= 0.2 pound
Answer:
x² - 3x - 10 = (x - 5) (x + 2)
x² - 3x - 18 = (x + 3) (x - 6)
Step-by-step explanation:
<u>x² - 3x - 10</u>
x² + 2x - 5x - 10
x(x + 2) - 5(x + 2)
(x - 5) (x + 2)
<u>x² - 3x - 18</u>
x² - 6x + 3x - 18
x(x - 6) + 3(x - 6)
(x + 3) (x - 6)
