Option B is not a function because it has two -2's.
Option C is a function.
Option D is not a function because it has two 6's.
Step-by-step explanation:
1)
3x+3
2)
10+2x
3)
8x+24
4)
8a+8b+8c
X = k x y
21 = k x 3
k = 7
x = 7y
x = 7(10)
x = 70
Answer:
7. x=19 2x=38
8.x=23 3x=69
9.x=12 (50-2)/4=12
10.x=15 (31-1)/2
11.x=16 (84-4)/5
12.x=27 (55-1)/2
Step-by-step explanation:
if 2 angles are opposite, it's the same
Yes, the equation is balanced. (brainliest?)
