Simplifying
2ab + 4ab = 0
Combine like terms: 2ab + 4ab = 6ab
6ab = 0
Solving
6ab = 0
Solving for variable 'a'.
Move all terms containing a to the left, all other terms to the right.
Divide each side by '6'.
ab = 0
Simplifying
ab = 0
Answer:
Step-by-step explanation:
let wind velocity=x
speed of plane=y
(x+y)*4=808
x+y=808/4=202 ...(1)
(y-x)*4=488
y-x=122 ...(2)
add (1) and (2)
2y=202+122=324
y=324/2=162
from (1)
x+162=202
x=202-162=40
wind velocity=40 m/hr
speed of plane=162 m/hr
Step-by-step explanation:
z= 21/12
divide bothside by 12

“Line graphs are useful in that they show data variables and trends very clearly and can help to make predictions about the results of data not yet recorded. They can also be used to display several dependent variables against one independent variable.”
“With a line graph, it is fairly easy to make predictions because line graphs show changes over a period of time. You can look at past performance in a line graph and make a prediction about future performance.”
