An advertiser goes to a printer and is charged $37 for 80 copies of one flyer and $54 for 209 copies of another flyer. The printer charges a foced setup cost plus a charge for every copy of single-page flyers. Find a function that describes the cost of a printing job, if 2 is the
number of copies made. C(x)

c(x) = y = $0.132*x + $27.16

Step-by-step explanation:

The chargers are a fixed price plus a charge for every copy, then we have a linear relationship.

A linear relationship can be written as:

c(x) = y = a*x + b

where a is the slope and b is the y-axis intercept.

For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:

a = (y2 - y1)/(x2 - x1).

In this case, c(x) = y represents the cost in dollars,  x is the number of copies bought, and b is the fixed cost.

We know two points in this line:

(80, $37) and (209, $54)

Whit those two points we can find the slope:

a = ($54 - $37)/(209 - 80) = $17/129 = $0.132 per copy.

Then our equation is:

c(x) = y = $0.132*x + b

To find the value of b, we know that 80 copies cost $37, we can replace those values in the equation:

$37 = $0.132*80 + b

$37 = $9.84 + b

($37 - $9.84) = $27.16 = b.

Then the equation is:

c(x) = y = $0.132*x + $27.16

answer: e 9, 5.75

step-by-step explanation:

step 1

find the variation ab in the x coordinate

delta x=(x2-x1)=10-> 8 units

find the variation ab  in the y coordinate 

delta y=(y2-y1)=6-> 2 units

step 2

find the coordinates point c

  x coordinate 

cx=ax+delta x*2/> cx=2+8*(2/> cx=3

  y coordinate 

cy=ay+delta y*2/> cy=4+2*(2/> cy=4.25

the coordinates of point c are (3,4.25)

step 3

find the coordinates point d

  x  coordinate 

dx=ax+delta x*4/> dx=2+8*(4/> dx=4

  y  coordinate 

dy=ay+delta y*4/> dy=4+2*(4/> dy=4.5

the coordinates of point d are (4, 4.5)

step 4

find the coordinates point e

  x  coordinate 

ex=ax+delta x*4/> ex=2+8*(6/> ex=5

  y  coordinate 

ey=ay+delta y*4/> ey=4+2*(6/> ey=4.75

the coordinates of point e are (5, 4.75)

step 5

find the coordinates point f

  x  coordinate 

fx=ax+delta x*4/> fx=2+8*(8/> fx=6

the coordinates of point f are (6,5)

step 6

find the coordinates point g

  x  coordinate 

gx=ax+delta x*4/> gx=2+8*(10/> gx=7

  y  coordinate 

gy=ay+delta y*4/> gy=4+2*(10/> gy=5.25

the coordinates of point g are (7,5.25)

step 7

find the coordinates point h

  x  coordinate 

hx=ax+delta x*4/> hx=2+8*(12/> hx=8

  y  coordinate 

hy=ay+delta y*4/> hy=4+2*(12/> hy=5.5

the coordinates of point h are (8,5.5)

step 8

find the coordinates point i

  x  coordinate 

ix=ax+delta x*4/> ix=2+8*(14/> ix=9

  y  coordinate 

iy=ay+delta y*4/> iy=4+2*(14/> iy=5.75

the coordinates of point i are (9,5.75)

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11-1 > 1-1+a

-12 > a
