By definition, 3 side lengths are a triangle if any 2 side lengths add up to be greater than the third.
We can already see that the side lengths 6 and 12 will add up to a value of 18, which is equal to the last side length, meaning that the three values are not a triangle.
(Since this is not true, this is not a triangle)
Hope this helps.
頑張って!
Answer:
<h2>y - 5 = x - 20</h2>
Step-by-step explanation:
The equation of a linear function in
slope-intercept form: 
point-slope form: 
standard form: 
general form: 
1.
y(x - 1) = 9
xy - y = 9 NO
2.
y - 5 = x(-x + 2)
y - 5 = -x² + 2x NO
3.
y(y - 1) = x + 25
y² - y = x + 25 NO
4.
y - 5 = x - 20
y - 5 = 1(x - 20) YES <em>(it's a point-slope form)</em>
Answer:
-3
Step-by-step explanation:
To estimate the amount Bradley would have at age 73 if he started investing in 40 we use the future annuity formula given by:
A=P[((1+r)^n-1)/r]
where:
P=principle
r=rate
n=time
thus plugging in the values we get:
A=12×550=$6600
n=73-40=33
r=7%
hence
A=6600[((1.07)^33-1)/0.07]
simplifying the ^ we get:
A=784,960.6054
Hence the answer is: $784, 960.6054
A. X is the number of years after 2000
2006-200 = 6 years.
Replace x with 6 and solve:
105(6)^2 + 680(6) + 4296 = 12,156
Answer for part a: 12,156
Answer for part B.
There was just over 12,000 in 6 years , to get to 21,500 would be a little over 9,000 more 9/12 = 0.75
6 years x .75 = 4.5 years
6 + 4.5 = 10.5 years round to 10 years for estimating purposes
Answer for part b: about 10 years
