Answer:
no
Step-by-step explanation:
6^2+7^2=9^2
36+49=81
no its not a right triangle
Y=x+1
3x+y=21
-----------
-x+y=1
3x+y=21
First do this. Change one (or both) of the equations so that the x and y are on one side, and the number is on the other. Make sure either the x or the y is the same in both equations (in this case, y) and then take one away from the other. The y will cancel out so you can work out x.
3x+y=21 -
-x+y=1
-----------
4x = 20
x = 5
Then add the x into one of the two equations to find out y.
3x + y = 21
(3*5) + y = 21
15 + y = 21
y = 6
To check, put both x any y into the other equation.
-5 + 6 = 1
If the answer is correct, you have correctly solved the equations.
x = 5
y = 6

I believe that B) m<3 would need to double. Since m<6 and m<3 are corresponding angles, they are always equal. So if 6 doubles, 3 needs to as well in order to be equal.
It starts at 100% - 15% = 85% after the first year. $15,000*0.85 = $12,750
The second year is further reduced 100% - 16% = 84%
$12,750*0.84 = $10,710

Honestly don't know how to explain this in any other way than just saying put it in a calculator. Sorry. :p
