There is only one change of sign, so there is only one possible positive root.
There are five changes of signs, so there are 5,3 or 1 possible negative roots.
The number of complex roots can be equal to 4,2 or 0 (degree of a polynomial - possible positive roots - possible negative roots)
<h3>
Answer: y = -x + 6</h3>
To get this answer, you subtract x from both sides to go from x+y = 6 to y = 6-x which rearranges to y = -x+6
Note that y = -x+6 is the same as y = -1x+6
We can compare this to y = mx+b form to see that m = -1 is the slope and b = 6 is the y intercept.
1500 divided by 100 is 15 .
Answer:
<h3>a) 9/2</h3>
Step-by-step explanation:
The formula of a slope:
We have the points (2, 5) and (0, -4). Substitute:
