Answer:
x≤−9 or x≥5 or x=0
Step-by-step explanation:
Let's solve your inequality step-by-step.
x2(x+9)(x−5)≥0
x4+4x3−45x2≥0
Let's find the critical points of the inequality.
x4+4x3−45x2=0
x2(x−5)(x+9)=0(Factor left side of equation)
x2=0 or x−5=0 or x+9=0(Set factors equal to 0)
x=0 or x=5 or x=−9
Check intervals in between critical points. (Test values in the intervals to see if they work.)
x≤−9(Works in original inequality)
−9≤x≤0(Doesn't work in original inequality)
0≤x≤5(Doesn't work in original inequality)
x≥5(Works in original inequality)
Answer:
x≤−9 or x≥5 or x=0

Answer:
Each person would have to contribute to contribute $385 to pay a 1.5 deficit.
Step-by-step explanation:
To determine:
How much would each person have to contribute to pay a 1.5 deficit if United States facing a budget deficit of 1.5 billion and 3.9 million population?
Fetching Information and Solution Steps:
- United States facing a budget deficit of 1.5 billion
- Population = 3.9 million
We have to determine how much would each person have to contribute to pay a 1.5 deficit.
Just dividing 1500 millions (1.5 billion) by 3.9 million as:
which is rounded to $385.
Therefore, each person would have to contribute to contribute $385 to pay a 1.5 deficit.
