Answer:
The average of the four numbers is 79.
Answer:
A: (-1,0)
B: (1,1)
C: (5,3)
(0,½)
(7,5) doesn't lie on the line
Step-by-step explanation:
Slope: (3-1)/(5-1) = ½
y = ½x + c
0 = ½(-1) + c
c = ½
y = ½x + ½
(0,½) is on the line
y = ½x + ½
Check for (7,5)
5 = 7/2 + 1/2
5 = 4 is a false statement
Answer:
y=3x/6+x
Step-by-step explanation:
Answer:
a = (-7)
Step-by-step explanation:
Firstly clear the bracket...,
-6(-2 + a) = 12 - 6a
Then substitute the simplified version in place of bracket...,
; 12 - 6a = 54
; -6a = 54 - 12
; -6a = 42...then divide both sides by (-6)
Therefore...., a = (-7)
