the second choice, and the last choice are correct.
the first one, x can be any number.
the second one, x can be any number but not -1(the denominator cannot be 0)
the third one, x has to be ≥ 1/2, because 2x-1 cannot be negative.
the fourth one, x can be any number but not -1 or -4
the last one, x can be any number but not -3
Answer:
Slope (m) = -1
Step-by-step explanation:
(2,1);(0,3)
(x1,y1)=(2,1)
(x2,y2)=(0,3)
Use the slope formula:
m = y^2 - y^1 / x^2 - x^1
= 3-1/0-2
=2/-2
=1
Answer:
30
Step-by-step explanation:
139+11 gives us 150 which is the total number of plates and 150/5= 30 so there were 30 plates in each package.
