All except the third selection are 0.
-12+12= 0
8+(-8)=0
-5+-5= -10
-20+20=0
-2,000+2,000=0
follow the the rules of integers
Answer:
CD = 24
Step-by-step explanation:
If G is the centroid, then CG = GD. (12 = 12)
Since CD is CG and GD combined, we would just add these two numbers to find the total length of CD.
CG + GD = CD
12 + 12 = 24
Answer:
it would be decreasing
Step-by-step explanation:
because it is a linear increasing function
for 1 it is going up from 1-6
and 2 it is a function because there isn't any multiples of the x values/ inputs that go to one y value/ output.
Use simultaneous equations:
2x + 7 = x^2 + 8x - 9
7 = x^2 + 6x - 9
16 = x^2 + 6x
+ or - 4 = 7x
answer is
-4/7 or 4/7
