1. The graph is hard to read. I would say about 4.3
2. It is very close to the same number 4.5
3. The 19-24 age group has the lowest number of wrecks in December
4.Teenagers and early 20's is the intended audience to show them the number or accidents caused by distracted driving by people of their age.
Let x be the number we are searching for.
(3/4)x = 1/10
The numbers are "x" and "y"
Therefore, we can suggest this system of equations:
x+y=10 ⇒x=10-y
xy=-60
Solve this system of equations by substitution method.
(10-y)y=-60
10y-y²=-60
y²-10y-60=0
Solve this square equation:
y=[10⁺₋√(100+240)]/2=(10⁺₋2√85)/2=5⁺₋√85
We have two solutions:
y₁=5-√85 ⇒x₁=10-(5-√85)=5+√85
y₂=5+√85 ⇒x₂=10-(5+√85)=5-√85
Answer: the numbers are (5-√85) and (5+√85)
