Answer: x = 2/3
Step-by-step explanation:
<em>Add all sides.</em>
2x-2 + 2x - 2 + x + x =
6x - 4
<em>Put " = 0 "</em>
6x-4 = 0
Add 4 to both sides.
6x-4 = 0
+4 = +4
-------------------
6x=4
You get 6x = 4 because the 4 on the left side of the equals sign cancelled out!
<em></em>
<em>NOW DIVIDE 6 FROM BOTH SIDES</em>
6x = 4
/6 /6
-----------
x= 4/6
<em>SIMPLIFY / REDUCE FRACTION</em>
4/6 divided by 2 = 2/3
2/3 is the answer !
The sign of f on the interval -7/3 < x < -3/5 is always positive.
<h3>How to solve for the sign on the interval</h3>
We have the equation
(5x+3)(x−2)(3x+7)(x+5) > 0
Now when f(x) > 0
Then -7/3 < x < -3/5
This would tell us that the sign would become positive when it changes from the less than to greater than sign
<h3>Complete Question</h3>
f(x)=(5x+3)(x-2)(3x+7)(x+5) has zeros at x=-5, x=-7/3, x=-3/5, and x=2
What is the sign of f on the interval -7/3<x<-3/5?
answer choices
f is always positive on the interval
f is always negative on the interval
f is sometimes positive and sometimes negative on the interval
f is never positive or negative on the interval
