Step-by-step explanation:
consecutive numbers follow each other thus if the first is x the second will be x+1 e.t.c:
1. x+x+1+x+2+x+3=2
x+x+x+x+1+2+3=2
4x=2-6
4x= -4
x= -1
The numbers are -1, 0, 1 and 2
2.x+x+1+x+2= -6
3x+3=-6
3x= -6-3
3x= -9
x=-3
The numbers are -3,-2 and -1

Answer:
Another way to identify the domain and range of functions is by using graphs. Because the domain refers to the set of possible input values, the domain of a graph consists of all the input values shown on the x-axis. The range is the set of possible output values, which are shown on the y-axis
True
work: f(3)=2(3)-9
f(3)=6-9
f(3)=-3
Answer:
angle DEC is 45 degrees
Step-by-step explanation:
angle DEC is 45 degrees because it is supplementary to 135 degrees
(with 135 degrees, adds up to 180 degrees)
