Answer:
The solution in interval notation is:
.
The solution in inequality notation is:
.
Step-by-step explanation:
I think you are asking how to solve this for .
Keep in mind .
If then .
Subtract on both sides:
Factor the difference of squares :
Simplify inside the factors:
The left hand side is a parabola that faces up. I know this because the degree is 2.
The zeros of the the parabola are at x=-6 and x=2/5.
We can solve x+6=0 and 5x-2=0 to reach that conclusion.
x+6=0
Subtract 6 on both sides:
x=-6
5x-2=0
Add 2 on both sides:
5x=2
Divide both sides by 5:
x=2/5
Since the parabola faces us and then we are looking at the interval from x=-6 to x=2/5 as our solution. That part is where the parabola is below the x-axis. We are looking for where it is below since it says the where is the parabola<0.
The solution in interval notation is:
.
The solution in inequality notation is:
.
For the first one, it would be a mile every half hour, or a mile and a half every hour. The second one would be 1 mile every twenty minutes. I think it would be safe to say an 1 hour and a half or answer choice "D" for this problem.
Let me now if I can be more of an assistance!
I believe it is a because I had a question just like that in 8th grade
2(c-3)=s
because you have to subtract 3 years from sherman's age first, so you need the parentheses
Answer:
4.51 ⁰ simplified would be 1 :)
It is 1 because anything to the 0 power is 1.
