Answer:
-5 is the value of a, 4 × -5 = -20
The first one I know for a fact is b^10
Answer:
Mean of 20 no.=18
Sum of 20 no.=20×18 i.e.360
When 2 is added to each no.,we get
360+(20×2)
=400
Now,new mean value of 20 no.=400÷20
=20
Step-by-step explanation:

Answer:
1/5
Step-by-step explanation:
The slope is given by the slope formula:
m = (y2 -y1)/(x2 -x1)
Using the first two points in the table, we have ...
m = (-2 -(-3))/(1 -(-4))
m = 1/5
The slope is 1/5.
All you need to do is divide -1/2 onto the other side.
-1/2x<-12
-12/ (-1/2)= 6 (a negative and a negative equals a positive)
Also, since you are dividing a negative, you flip the sign.
x>6
I hope this helps!
