Answer:

Answer:

( {x}^{} + 2) {}^(2) = {x}^(2) + 4x + 4

(2x - 3) {}^(2) = {4x}^(2) - 12x + 9

{(3x + 4)}^(2) = {9x}^(2) + 24x + 16

{(x - y)}^(2) = {x}^(2) - 2xy + {y}^(2)

{(2x + 3y)}^(2) = 4x {}^(2) + 12xy + 9y {}^(2)

Write a system of equations to describe the situation below, solve using substitution, and fillin the blanks.Nora, an office manager, needs to find a courier to deliver a package. The first courier she isconsidering charges a fee of $14 plus $5 per kilogram. The second charges $15 plus $4 perkilogram. Nora determines that, given her package's weight, the two courier services areequivalent in terms of cost. What is the weight? How much will it cost?

Answers

The first courier service cost is;

5x+14

Where, x is the number of kilograms delivered;

The second courier service cost is;

4x+15

Equating it, we have;

\begin{gathered} 5x+14=4x+15 \n x=1 \end{gathered}

Thus, the weight that will result in equal cost is 1 kilogram.

And the cost is 5( 1 )+14 = $19

What is the value? 3/4 + 7/12 - (-4)

Answers

Answer: 3/4 + 7/12 - (-4) = 3/4 + 7/12 + 4 (two minuses make a plus)

3/4 + 7/12 + 4/1 = 9/12 + 7/12 + 48/12           (4 = 4/1 or 4 divided by 1)  

(to add the fractions the denominators need to be the same. Multiply both the denominator and numerator by the same number)

(9+7+48)/12 = 64/12 = 5 and 1/3 or 16/3

We can also get this answer by leaving the 4 as a whole number:

9/12 + 7/12 +4 = 16/12 + 4 = 1 and 1/3 + 4 = 5 and 1/3

If you put the sum in a calclator you also get 5 and 1/3.

Hope this helps :)

Find the percent change from a stock that was worth $230 and is now $287

Answers

Answer:

24.78%

Step-by-step explanation:

Initial price = $230

Final price = $287

change in price = final price - initial price

= 287 - 230

= $57

Percent change

= (change in price / initial price) x 100%

= (57 / 230) x 100%

= 24.78%

Find the quotient: –10/19÷(−5/7)

Answers

Answer:

14/19

Step-by-step explanation:

Note that there are two " - " signs here.  Thus, the end result will be " + "

We move from left to right, obtaining first 10/19 divided by (5/7):

10

----- ÷ (5/7)

19

To divide by (5/7), invert (5/7) and then multiply.  We get:

10      7      2(7)

----- * ----- = ------- = 14/19

19       5       19
