Answer:
<em>The perimeter of the rhombus is 20 cm</em>
Step-by-step explanation:
<u>Perimeter of a Rhombus</u>
Given the lengths of the two diagonals of a rhombus, let's call them a and b, the perimeter of the rhombus is given by:

The values of the diagonals provided by the question are a=6 cm, b=8 cm, thus the perimeter is:




The perimeter of the rhombus is 20 cm

Step-by-step explanation:
The number of printers sold is modeled by the function:

The price per printer is modeled by
,where t is the number of years since 2003.
From 2009 to 2003, we have t=6 years.
The number of printers sold is 
The price per printer is
,
The revenue generated is a number of printers times unit price.

Answer:
Step-by-step explanation:
you do part a
Equation 1: 4x+y=2
Equation 2: 3x-3y=9
b
Divide equation 2 by 3
x-y=3
add y to both sides
x=3+y
Sbustitute this into equation 1
4(3+y)=2
12+4y+y=2
5y= -10
y= -2
Plug this into equation 1
4x-2=2
x=1
Part c.
Equation 1: 4x+y=2
Equation 2: 3x-3y=9
divide equation 2 by 3
x-y=3
add the two equations
(x-y)+(4x+y)=2+3
5x=5
x=1
Plug this into equation 1
4(1)+y=2
4+y=2
y= -2
For part a just create a table and graph it
