Answer:
C
this is because from the decimal point to the right we start from tenth to hundredth
No, these do not always forma unique triangles because it depends on what size your sides are because if you have 3 sides of the same length then that’s a equilateral and if you have two sides of the same length and one side that’s not then that would be an Isosceles triangle and if you had no sides of the same length then that would be a scalene triangle.
(5x+17)+129+94+(7x-46)+(9x-11)=540
5x+7x+9x+17+129+94-46-11=540
21x+146+94-57=540
21x+240-57=540
21x+183=540
-183 -183
21x=357
/21 /21
x=17

Answer:
Step-by-step explanation:
According to the trigonometric identities we have the following formula:
Now, we have the following:
Where and
Hence:
Finally:
this means
from x<-2 only graph y=3 but not -2
from -2<=x<2 only graph -x/2+2 but not 2
from x>=2 only graph 2x-3 including 2
the closest graph is the first but its has a mistake, on the middle graph the circle should not be shaded in
