Answer:
n = 25
Step-by-step explanation:
9 / n+2 = 2/6
can be written as
n+2 / 9 = 6/2
n+2/9 = 3
n+2 = 3 * 9
n+2 = 27
n = 27 - 5
n = 25
Answer:
<u>3rd graph (on bottom left)</u>
Step-by-step explanation:
First, find the <u>zeros of the function</u>.
- f(x) = x² - x - 2
- f(x) = x² + x - 2x - 2
- f(x) = x(x + 1) - 2(x + 1)
- f(x) = (x - 2)(x + 1)
The zeros are :
- x - 2 = 0 ⇒ x = 2
- x + 1 = 0 ⇒ x = -1
Therefore, the graph of the function intersects the x-axis at :
The correct graph is <u>3rd graph (on bottom left)</u>
