The cost for a certain music plan is 9.99 per year plus $.025 per song you download if you paid $113.74 one year find the number
garri49 [273]
Y=amount of money paid.  (in $)
x=number of songs download.

We have this function:
y=0.25x+9.99

Then:
if y=113.74

113.74=0.25x+9.99
0.25x=113.74-9.99
0.25x=103.75
x=103.75 / 0.25
x=415

Answer: the number of songs downloaded would be 415.

50 POINTS
NeX [460]

Answer:

o I = 4 cm, w = 9 cm, h = 3 cm  

Step-by-step explanation:

The volume is given by V = l*w*h

w = 6 cm, I = 4,cm, h = 4 cm    V= 6*4*4 = 96

o w = 7 cm, h = 3 cm, I = 5 cm   V = 7*3*5 =105

o I = 4 cm, w = 9 cm, h = 3 cm   V = 4*9*3 =108

o h = 5 cm, w = 6 cm, I = 3 cm  V = 5*6*3 =90

The largest volume is

o I = 4 cm, w = 9 cm, h = 3 cm   V = 4*9*3 =108

Which algebraic rule describes the translation of ADEF to AD'E'F?
Marrrta [24]

Answer:

B: (x, y) --> (x + 4, y - 3)

Step-by-step explanation:

the shape DEF went to the right along the x axis wich <em>increased</em> x and then went down the y axis or <em>decreased </em>y to make D'E'F'

some good way to remember these translations and orders are...
 - x is first when plotting points, then y (x, y)
 - x increases going right, and decreases going left, as well as y increasing going up, then decreasing going down

BONUS FACT:
the symbol ( ' ) is called a prime when refering to transformations and geometry ((as in D' is pronounced D prime))
