Answer:
m ≠1 ( all m in R except 1 )
Step-by-step explanation:
hello :
mx − y + 3 = 0.....(*)
(2m − 1)x − y + 4 = 0 ....(**)
multiply (*) by : -1 you have : -mx+y-3=0 ....(***)
(2m − 1)x − y + 4 = 0 ....(**)
add(***) and(**) : -mx+ (2m − 1)x+1 =0
(2m-m-1)x+1=0
(m-1)x = -1
this system have no solution if : m-1≠0 means : m ≠1
Answer:
d. backward sloping.
Step-by-step explanation:
The roommate receives a pay raise at her part-time job from $9 to $11 per hour and now decides to work 20 hours per week instead to 25 hours per week.
We can see that her rate is decreasing, so her labor supply curve is backward sloping or also called backward bending.
It is mostly found that worker's labor supply curve, slopes upward when they get lower wages and the curve bends backward when they get higher wages because a worker tends to work less when his wage rate rises.
Answer:
Lisa's team have played 24 home games and 25 away games.
Step-by-step explanation:
Given:
Let 
represents games played at home.
also 
represent games played away.
Total number of games played = 49
∴ 
Now according to given data:
Number of home games won = 
Number of away game won = 
Total games won =26
Hence
Now multiplying equation 1 by 3 we get,
Now Subtracting equation 2 by equation 3 we get,
Substituting value of x in equation 1 we get.
Hence Lisa's team have played 24 home games and 25 away games.
