Find the sum of the first 12 terms of the sequence. show all work for full credit. 1,-4,-9,-

Let's find the rule where.

1-(-4)=5

-4-(-9)=5

It looks like we are subtracting 5 from the previous number. Since we know the rule, let's write out all.

1, -4, -9, -14, -19, -24, -29, -34, -39, -44, -49, -54; let's add them.

-318 is the sum

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
