If a = 5, B = 4, and c = 7, find the value for 3(b + a) - c.

A. 34

B. 20

20

Step-by-step explanation:

=> 3(b+a)-c

Putting a = 5, b = 4 and c = 7

=> 3(4+5)-7

=> 3(9)-7

=> 27-7

=> 20

square root

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.
