What is the value of 6(3b-4) when b=4?

72-24

Step-by-step explanation:

6(3 x 4-4)

6(12-4)

Distributive property

72-24

48

Step-by-step explanation:

b=4    6(3b-4) (replace b with 4)

6(3(4)-4)    ( distribute 3 to the 4)

6(12-4)  (subtract with in the parenthesis)

6(8)   ( multiply)

48

f-1(x)= cube root of 19x squared/x

step-by-step explanation:

  y= -3x is the required function.

step-by-step explanation:

we have been given a table:

x             y

0             0

1             -3

3             -9

-2             6

we can see that the values of y is -3 times the value of x

hence, the function would be: y= -3x.

put the values of x will give the same y as in the table that means function is satisfying the given table.
