The problem consists in changing a fraction to percent form, a percent is a quantity divided by 100, for example, 50% is equal to 50/100, so lets modify the fraction for it to have 100 as denominator.
so we divide the numerator and denominator by the same number so the fraction does not alterate, keeps being equivalent that is:
2/300
we need to divide the numerator and denominator by 3:
<span>2/300 = (2/3)/(300/3)
</span>= (2/3)/100
now we have it, 2/300 as percent is (2/3)% = 0.67%
Answer:
The graph is positive and decreasing for all real values of x where x < -1
Step-by-step explanation:
we have
The function is a vertical parabola open up
The roots (x-intercepts) are x=3 and x=-1
The vertex is the point (1,-4 ) is a minimum
using a graphing tool
see the attached figure
we know that
In the interval (-∞,-1) ---> the function is positive and decreasing
In the interval (-1,1) ---> the function is negative and decreasing
In the interval (1,3) ---> the function is negative and increasing
In the interval (3,∞) ---> the function is positive and increasing
therefore
The graph is positive and decreasing for all real values of x where x < -1
That's a tough problem to type out! Thanks for sharing this image of the original expression.
What I'd do would be to write:
(fourth root of 9)^(x/2) = [ (9)^(1/4) ]^(x/2) = 9^(x/8)
so the second of the four possible answer choices seems correct.
−2w−2<−8
Step 1: Add 2 to both sides.
−2w−2+2<−8+2
−2w<−6
Step 2: Divide both sides by -2.
−2w
−2
<
−6
−2
w>3
