Answer:

Step-by-step explanation:
Square root of 16 ×9×3= square root of 432
square root of 16 =4
square root of 9 =3
That will equal 4×3× square root of 3 which finally equals to 12 square root of 3.
Answer:
Step-by-step explanation:
f(x) = -2x
x & f(x)
-2 is 4
-1 is 2
0 is 0
1 is -2
2 is -4
f(x)=-2x-4
x & f(x)
-2 is 0
-1 is -2
0 is -4
1 is -6
2 is -8

Ok so first, let's combine the like terms on the right side by adding them

Now we look at them put back together

Now you have to move all your y's to one side and numbers without a variable to the other. So, for this we're going to add 6y to 7y on the right so the left side cancels out.

On the other side we subtract 6 from 19

and now to get the answer for y we divide 13 by 13 to get your answer of 1 :)
