HELP ME PLEASE WILL GIVE BRAINLEIST
answer and put something down for each "test it"

the first one is false,the second one is true,the third one is false and the last one is true

1. False, 2. True, 3. False, 4. True

1. False~sum of rational + rational= rational not irrational

2. True~ product of rational x irrational= irrational

3. False~ product of nonzero rational x irrational= irrational not rational

4. True~ sum of rational + irrational= irrational

Step-by-step explanation:

1.= 1 1/2 + 5= 6 1/2 this is rational not irrational so~ False

1.4

2.3

step-by-step explanation:

the formula for the constant of variation is

y= kx

divide each side by x

y/x =kx/x

y/x =k

we know a and y

1.   y/x = k

4/1 =4

check the other values to make sure they are the same

8/2 = 4   12/3 =4   and 16/4 =4  

the constant of variation is 4

2.   y/x = k

3/1 =3

check the other values to make sure they are the same

6/2 = 3   9/3 =3   and 12/4 =3  

the constant of variation is 3

3 is greater then both of those numbers
