Answer:

-9

Step-by-step explanation:

In synthetic division we are multiplying the number -1 with the number written at the last line.

So here first we multiplied -1 with 3 to get -3, write it down below -4.

Now when we add -4 and -3 we get -7.

Again we multiply -1 with -7 , to get 7, writing it down below 2.

Then we add 2 and 7 to get 9.

Again we multiply -1 with 9 , that will give us -9.

So we write -9 below -1 in last column to get -10.

So the missing number is -9.

how is solving inequalities with addition and subtraction similar to and different from solving equations with addition and subt
SpyIntel [72]

The difference between solving equations and solving inequalities is: If you multiply or divide an inequality by a negative number, then the inequality reverses. !!!!!
