Answer:
c) (8^6) / 8 = 32768
d) (7^8) / (7^6) = 49
Step-by-step explanation:
256-192= 64
192-144=48
144-108=36
108-81=27
81- 60.8=20.2
60.8-45.6=15.2
45.6-34.2= 11.4
34.2-25.6=8.6
25.6-19.2= 6.4
19.2-14.4= 4.8
To find the answer, you must find the midpoint of their x-coordinates and their y-coordinates. To do that, you take the average between their x and y-coordinates.
So, in this case, it is:
x: (12+12)/2 = 24/2 = 12
y: (7-3)/2 = 4/2 = 2
So, the answer is: (12,2)
Sum means addition
negative 18 means -18
a number can be x
Sum of negative 18 and x should be 11
thus the equation is
