Answer:
2x -18x +14y -19 = -16x +14y -19 . . . not the same
-2xy -1 . . . not the same
16x +14y -1 . . . not the same
9 -16x +14y -10 = -16x +14y -1 . . . equivalent
-16x +14y -1 . . . equivalent and simplified
2x -18x +14y -1 = -16x +14y -1 . . . equivalent
Step-by-step explanation:
Answer:
We have to travel 26.93 units from platform B to C.
Step-by-step explanation:
Length of a segment having coordinates
and
is determined by the formula,

From the graph attached,
Coordinates of the points B and C are (-25, -20) and (-15, 5) respectively.
Distance between these points B and C Or length of BC will be,
BC = 
= 
= 
= 
= 26.93 units
Therefore, we have to travel 26.93 units from platform B to C.

Answer:
n=-3
Step-by-step explanation:
11(n – 1) + 35 = 3n
expand left side
11n-11+35=3n
Add-11 to 35
11n+35-11=3n
11n+24=3n
subtract 24 from both sides
11n+24-24=3n-24
11n=3n-24
subtract3n from both sides
11n-3n=3n-24-3n
8n=-24
divide both sides by 8
8n/8=-24/8
n=-3
