Answer:

2(57x^{2}-8)

Step-by-step explanation:

Given: 114x^{2} -16

To factor, we always look for a greatest common factor. In this case, the greatest common factor is 2. Let's factor that out:

2(57x^{2}-8)

There is nothing further to factor out in this expression, so this would be your final answer.

The number of students in Mrs. Patrick's piano class decreased by 15% in 2 years to 17 students. How many students did she have
guapka [62]

Answer:

20 students

Step-by-step explanation:

If the class decreased by 15%, the students that she has now (17) represents a percentaje of:

100% - 15% = 85%

so<u> the 17 students are 85% of what she had</u>:

Students         Percentage

      17          ⇒        85%

and we are looking for how many students she had 2 years ago, thus we are looking for the <u>100%</u> of students (the original number of studens). If we represent this number by x:

Students         Percentage

      17          ⇒        85%

      x          ⇒        100%

and we solve this problem using the <u>rule of three</u>: multiply the cross quantities on the table( 17 and 100) and then divide by the remaining amount (85):

x = 17*100/85

x = 1700/85

x=20

2 years ago she had 20 students

A company makes greeting cards and their research shows that that price and demand are related linearly: p = mx + b. They know t
Andrew [12]

Answer:

p = -0.05x+22

Step-by-step explanation:

The general linear equation of price-demand is

(1) <em>p = mx + b </em>

<em> </em>

where x is the demand of cards in units when they are sold at x dollars.

If for every additional card they wish to sell they need to drop the price by $0.05, then

(2) p-0.05 = m(x+1)+b

To sell 360 cards they need to set the price at $4, so

(3) 4 = m.360+b

We need to find m and b.

Operating on eq. (2) we have

p-0.05 = mx+m+b  

 

mx+b-0.05 = mx+m+b

m = -0.05

Replacing this value in (3)

4 = (-0.05)360 +b

4 = -18+b

b = 22

So, the linear equation relating price p to demand x is

p = -0.05x+22

See graph attached.
