Answer:
17
Step-by-step explanation:
Given
Finding the second term of the sequence means to find To find substitute into the second expression:
You have to solve it first.
2x+4y=-8
-2 =-2
-10
4y=-10
---
4y
4 divided by -10 is -4
Answer:
k = 10
Explanation:
The initial polynomial is:
If f(-2) = 0, then when we replace x by -2, the result will be 0. It means that we can write the following equation:
Therefore, we can solve for k as follows:
So, the value of k is 10
Answer:
1/15
Step-by-step explanation:
Answer:
(4x+5)/[(x-1)(x-2)]
Step-by-step explanation:
(4x+5)/(x^2-3x+2)
factor out the trinomial x^2-3x+2 first,
find two numbers that when they multiply, you get the third term, which is 2 in this case. And when they add up, you get the second term, which is -3 in this case. x^2-3x+2=(x-1)(x-2)
