F(x) = x^3 + 2x^2 - x - 2
<span>f(x) = x^2(x + 2) - (x + 2) </span>
<span>f(x) = (x^2 - 1)(x + 2) </span>
<span>f(x) = (x + 1)(x - 1)(x + 2) </span>
<span>Roots: -1, 1, -2 </span>
Answer:
2/5 or 40%
Step-by-step explanation:
.40 is 40 hundredths or 40/100
40/100 can be reduced to 20/50 and reduced again to 10/25 and one more time to 2/5
Percentages are fractions out of 100 so 40/100 would be 40%.
If you would like to write y - x - 1 = 0 in the general form, you can do this using the following steps:
The general form of the equation is: ax + by + c = 0.
y - x - 1 = 0
-x - y - 1 = 0
The correct result would be <span>-x - y - 1 = 0</span>.
Answer:
Did you ever get the answer?
Step-by-step explanation:
Answer:
<u>D) x² - y = 10x + 25 + y</u>
Step-by-step explanation:
A relation only becomes a function if each x-value only has a single y-value as the answer.
<u>Evaluating</u>
- A and B cannot be the answers as each value will get 2 answers
- C will also not be the answer as y² means at least 2 answers will be given
- <u>D</u> is the best option as each inputted x-value will get an answer of a single y-value
