What is the sum of the polynomials? (8x^2-9x^2-4x)+(x^2-3y^2-7x)

The sum of the polynomials is -11x - 3y^2.

In order to find this we must first collect all like terms. To start, we'll begin with all x^2 terms.

8x^2 - 9x^2 + x^2 = 0

Since these all cancel, we're left with no x^2 term. Next we'll do x terms.

-4x - 7x = -11x

The only thing left is -3y^2, which has no alike term. so we just include that in there.

-11x - 3y^2

Translate and solve: eight more than the product of three and a number is -13
Murrr4er [49]
Ok, so let’s take the given phrase.
Eight more than the product of 3 and a number is -13. A translation to numbers looks like this:
3x + 8 = -13
Now, let’s solve for x. We can start the process by subtracting 8 from both sides.
3x = -21
now, we will divide each side by 3 to isolate the variable, thus solving for x.
x = -7

Carissa and Louann both have savings accounts. Carissa has $250 in her account and deposits $80 per month. Louann has $1230 in h
zlopas [31]
Carissa value after x months=current+amount deposited
louan value after x months=current-amount taken out

carissa depositied=amount per month times x months=80x
louan take out=amount per month tiems x months=60x

when wil amount be equal
se equal

cariss=lousa
250+80x=1230-60x
add 60x both sides
250+140x=1230
minus 250 both sides
140x=980
divide both sides by 140
x=7

find how much that is
250+80(7)=250+560=810
