For each inequality is x=5 a solution?? A. x<2
B. x>9
C. x<18
D. x>42

c

Step-by-step explanation:

replace x in each problem with 5 since x equals 5.

5<2 ,, false

5>9 ,, false

5<18,, true

5>42,, 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

my answer is$ 12

step-by-step explanation:

because 15 -2=12
