Answer:

1 new and 5 used

Step-by-step explanation:

If we subtract multiples of 250 from 625 and divide by 75, we can determine the number of phones.  

We know that 250(2) = 500; if we subtract this from 625, this leaves

625-500 = 125 for the old phones.  Dividing this by 75, we see that it is not a whole number; this means there cannot have been two of the new $250 phones sold.

625-250 = 375.  Dividing this by 75, we get 5; this means 1 new phone and 5 old were sold.

Please help <br><br> questions 12,14,16
notka56 [123]

Answer:

12) y=3x-15

14) y=-1/2x

16) y=13x-105

Step-by-step explanation:

Parallel lines always have the same slopes but different y-intercepts. So, we can make the equation (b is y-intercept of new equation):

12) y=3x+b

14) y=-1/2x+b

16) y=13x+b

now, we can plug in each of the coordinates given to these equations.

12) (4,-3): 4 is x, -3 is y.

       -3=3(4)+b

      simplify: b= -15

14) (-4,2): -4 is x, 2 is y

      2=-1/2(-4)+b

        simplify: b=0

16) (9,12): 9 is x, 12 is y

       12=13(9)+b

       simplify: b=-105

Now, plug in those numbers to your equation for b value.

12) y=3x-15

14) y=-1/2x

16) y=13x-105

*for 14 we don't need to write anything after -1/2x because b=0*

Madison invests money in an account paying a simple interest of 3.2% per year.If she invests $160 and no money will be added or
Tamiku [17]

The amount of interest she will earn in one year will be 5 dollars and 12 cents.

<h3>What is Simple interest?</h3>

The normal interest levied on the amount borrowed from any bank on a yearly basis is called the simple interest.

Given that:-

  • The interest of 3.2% per year
  • Invests $160 and no money will be added or removed from the investment.

The simple interest amount will be:-

SI   =   (  P   x   R   x   T  )  / 100

SI  =    (  160   x   x   3.2   x   1  )  /   100

SI   =    $5.12

Therefore the amount of interest she will earn in one year will be 5 dollars and 12 cents.
