The correct answers are: 1/2, 2 and -2.
To get this, factor f(x)
f(x)=2x^3-x^2-8x+4
f(x)= (2x^3-x^2) - (8x -4)
f(x)= (2x-1)(x^2) + (2x-1)(-4)
f(x)= (2x-1)(x^2-4)
f(x)= (2x-1)(x-2)(x+2)
2x-1=0
2x=1
x=1/2
x-2=0
x=2
x+2=0
x=-2
Answer:
-8 < x, the answer is B
Step-by-step explanation:
Since its starting from -8 and your going to the greater side of the numberline teh variable will be greater than -8, whenever the circle is filled it just means greater than or equal to depending on which side its going. If its filled in, it means that its greater than or equal to or less than or equal to depending on which side its going towards.
Reminder:
<--------------- Negative side/Lower -----------------------> Positive side/Greater
Answer:
p=0.75L (General equation)
A. When L=1m
p=0.75×1
p=$0.75
B. When p=$1.50
Substituting p into the general equation;
1.50=0.75L
L=1.50/0.75
L=2m
He is currently 47.
56-9=47 and if you switched it around it would be 47+9=56 so the answer is 47.
