Answer:

- 5yz^2 - 3z^2 - 5y + 7

Step-by-step explanation:

The polynomial is:

-yz^2-3z^2-4y+4   ( 1 )

this polynomial is the result of the sum of two polynomials, one of them given by

y-4yz^2-3     ( 2 )

if you find to know what is the other polynomial, you can take the difference between the polynomial (1) and (2). It is necessary to take the difference between simmilar terms, as follow:

 - yz^2 - 3z^2 - 4y + 4

<u>- (4yz^2          + y   - 3  )</u>

<u />

 - yz^2 - 3z^2 - 4y + 4

<u> - 4yz^2           - y   + 3  </u>

- 5yz^2 - 3z^2 - 5y + 7

hence the other polynomial is - 5yz^2 - 3z^2 - 5y + 7

Jane earns a 5.5% commission on the selling price of each home she sells. She earned $9,020 in commission on the sale of a home.
ratelena [41]

Answer:

"$164000" is the appropriate answer.

Step-by-step explanation:

Let the selling price be "s".

As per the question,

If Jane take 5.5% of selling price i.e.,

= 0.055\times s

Given commission,

= $9,020

then,

The selling price will be:

⇒ 0.055\times s=9020

                s=\frac{9020}{0.055}

                   =164000 ($)

Determine the x-intercept for 3x + 2y = 14.
spin [16.1K]

First isolate y

3x + 2y = 14

-3x              -3x

2y = -3x + 14

y = -3/2x + 14/2

y = -3/2x + 7

X-intercept is found when y = 0

0 = -3/2x + 7

-7 = -3/2x

x = 14/3

x-in. = (14/3,0)
