The best answer to go with is b
Answer:
x = -5/7, 2
Step-by-step explanation:
Step 1: Factor
(5x + 7)(x - 2) = 0
Step 2: Find <em>x </em>roots
5x + 7 = 0
x = -5/7
x - 2 = 0
x = 2
Answer: -9n+20
This is the same as 20-9n
================================================
Explanation:
The jump from 11 to 2 is "minus 9"
The jump from 2 to -7 is also "minus 9".
Assuming this pattern continues on, we have an arithmetic sequence with
- a = 11 = first term
- d = -9 = common difference
The nth term can be found like so

Let's check the answer by trying n = 3

This shows the third term is -7, which matches what the original sequence shows. The answer is partially confirmed. I'll let you check the other values of n. You should get 11 when trying n = 1, and you should get 2 when trying n = 2.
Answer:
g(f(2)) = 9
Step-by-step explanation:
Evaluate f(2) and substitute the value obtained into g(x)
f(2) = 2 + 1 = 3 , then
g(3) = 3² = 9
