Answer:
If your polynomial is x^2+x-30, then your answer is (−5)(+6)
In order to derive the base of a triangle from its area, you need its height as well.
In fact, if we solve the area formula for the base, we have

So, the base length would be

where h is the height relative to the base you're interested in.
You have to consider the “ends” of the x-axis, the far right (for infinitely large values of x) and left (for infinitely small values of x) of the graph.
From the diagram above you can see that:
- When
then
(notice that as the values of x get smaller and smaller, the graph gets closer and closer to the line y=1); - When
then
(notice that as the values of x get larger and larger, the graph gets closer and closer to the line y=1).
Answer: correct choice is D.
to calculate the slope m , use the ' gradient formula '
m = 
with (
,
) = (0, - 1 ) and (
,
) = (1, 5 )
m =
= 6
0
Answer:
Call the number we need to find a.
Inequality: (12 + a) ÷ 2 < 27
<=> 12 + a < 54
<=> a < 54 - 12
<=> a < 42
