The answer of the given equation is  -13y^{2} -11y+7

Step-by-step explanation:

The given equation can be written as,

(-8y^{2}+6y-1) +(-8y^{2}+8y+1)-(-3y^{2}+9y-9)

= -8y^{2} +6y-1-8y^{2}-8y -1+3y^{2}-9y+9

[Taking same powered variables together we get,]

=(-8y^{2}-8y^{2}+3y^{2}) +(6y-8y-9y)-1-1+9

= -13y^{2} -11y+7

Here the answer.

Parker marks sixths on number line. He writes 5/6 just before 1. What fraction does he write on the first mark to the right of 1
VashaNatasha [74]

Answer: 7/6

Step-by-step explanation:

If he is writing sixths, then we have multiples of 1/6.

this is:

0*(1/6) = 0

1*(1/6) = 1/6

.

.

.

5*(1/6) = 5/6 (the numer he wrote at the left of 1)

6*(1/6) =  6/6 = 1

7*(1/6) = 7/6

So the number next to 1, (at the right of 1) must be 7/6.

You also can find it by adding 1/6 to 1.

1/6 + 1 = 1/6 + 6/6 = 7/6.
