Solve and graph this if you can 3(2⋅7)≤6(x−4)

x ≥ 11

Step-by-step explanation:

42 -  6 • (x - 4)  ≤ 0

66 - 6x  =   -6 • (x - 11)

 -6 • (x - 11)  ≤ 0

x ≥ 11

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

4a. is 3 miles every hour

4b. is 1/3 of an hour per mile
