Let the line be y= mx+C
Passes through origin i.e (0,0)
Hence 0= m×0+C →C=0
Hence line becomes y= mx
Passes through origin i.e (10,5)
Hence 5= m×10→m=5/10= 0.5
Hence line becomes y=0.5 x
Answer:
a
Step-by-step explanation:
When you multiply the top equation by 3 you would get 6x when you multiply the bottom equation by -2 you would have -6x that way when you combine the equations they would eliminate each other and you would only be left with y as a variable
It’s depends on the sign.
For example if your question is 3x+16y-8-7x+8y then the answer would be -4x+24y-8 if they have the same variable look at them as a separate equation.
the given sets are,
D= {4,7,9} , let E {4,6,7,8}, and let F={3,5,6,7,9}
now,
D U E = { 4 , 6, 7 , 8, 9}
and'
E intersection F = E n F = {6 , 7)
thus, the answer is
D U E = { 4 , 6, 7 , 8, 9} and
E n F = {6 , 7)
It's being divided by 5.
