Answer:
5
Step-by-step explanation:
coefficeint is the number before the variable
Count by 1 1/2's<br><br>
0, 1 1/2, _, _, _, _, _, 10 1/2, _, _, 15
DanielleElmas [232]
2, 2 1/2, 3, 3 1/2, 4, 41/2, 5, 5 1/2 6, 61/2 so on and so forth
We have 4(k-6)-(3k+2)=-5 and the answer is k=21
Add 2x^2 to both sides
7x^2-2x-6=9x
Subtract 9x from both sides
7x^2-11x-6=0
Factor by using slip and slide
x^2-11x-42
(x-14)(x+3)
(x-14/7)(x+3/7)
(x-2)(7x+3)
Then use the Zero Product Property to find roots
x-2=0
x=2
7x+3=0
7x=-3
x=-3/7
Final answer: x=-3/7, x=2
