D is the only point that is a solution to the graph.
You can tell this in two ways. Firstly, you can look into the graph and find the points that are in between the two parabolas. You'll notice only D falls between those two.
The second way is that you can plug into each equation algebraically to see if they produce true statements. D produces two true statements.
y < x^2 + 2
-2 < 0^2 + 2
-2 < 2 (TRUE)
y > x^2 - 6
-2 > 0^2 - 6
-2 > -6 (TRUE)
X=-2/5
Steps:
6^x/3 +2 = 6^-14x/3
x/3+2 = -14x/3.
x +6 = -14x (multiply both sides by 3)
x = -14x - 6 (Substract 6 from both sides)
x + 14x = -6 (add 14x to both sides)
15x = -6 (collect like terms)
x = -2/5 (divide both sides by 15)
The Area of the Triangle is A = 135
Answer: 450 minutes
Step-by-step explanation:
4 hours and 30 minutes equals 4.5 hours.
3+4.5=
7.5 hours
1 hour equals 60 minutes
Hence,
7.5*60=
450 minutes
