Answer:

10y

Step-by-step explanation:

9y is equal to y+y+y+y+y+y+y+y+y.

If you add y to that you get (y+y+y+y+y+y+y+y+y)+y, which is equal to 10y.

Answer:

10y

Step-by-step explanation:

9y+y=10y

If you set y to a value such as 2, you'd get:

18+2=20 which means 10y is correct.

Simplify the difference. (–7x – 5x^4 + 5) – (–7x^4 – 5 – 9x)

sineoko [7]

Answer: $2x^4+2x+10$

Step-by-step explanation:

You need to remember the mulplication of signs:

$(+)(+)=+\\(-)(-)=+\\(-)(+)=-$

Knowing this, you can distributive the negative sign. Then you get:

$(-7x- 5x^4 + 5) - (-7x^4 - 5 - 9x)=-7x- 5x^4 + 5 +7x^4 + 5 + 9x$

Now you need to add the like terms. Then:

$=2x+2x^4+10$

Finally, you can order the polynomial obtained in descending order. Therefore, the answer is:

$=2x^4+2x+10$
