C!
parallel line: m1 x m2 = -1
-3 x 1/3 = -1
For A the great common factor is 3 because if you were to do 3,6,9 and then 36- 3,6,9,12,15,18,21,24,27,30,36 the greatest common factor (GCF) would be 3.
For B the greatest common factor is 28 because if you were to do 7,14,21,28, twenty-eight is the highest number possible and for 42 you would do 7,14,21,28,35,42 the highest number possible for them to match would be 28 so the answer is 28 for B
Answer: е) Step-by-step explanation: we know the coordinates of the points so we can easily determine which function this is To begin with, let's take any two points with an integer coordinates let these be two points with coordinates (1 ; 4) and (0 ; 3) Now let's check
and all other options except option e are incorrect because
D--because it has y^2 in the equation and to isolate y you have to take the square root, the graph is going to be curved rather than linear.
Answer:
D
Step-by-step explanation:
30 : 13 = 30/13
