First we graph the given points
For the equation to be proportional, the line should pass through the origin (0,0), then this equation is not proportional.
Answer:
<em>Part A: </em>
<em>c = 1.15p</em>
<em>c(2) = $2.30</em>
<em>Part B: </em>
<em>c = 0.90p</em>
Part B:
Step-by-step explanation:

Candy's Sweets Company charges $1.15 per pound to ship candy. This represents a proportional relationship between the pounds of candy and the cost.
Part A: If each pound costs $1.15, then p pounds cost $1.15p. Then the equation of the cost c is:
c = 1.15p
The cost of shipping p=2 pounds of candy is:
c = 1.15*2 = 2.30
c = $2.30
Part B: When the company reduces the cost by $0.25 per pound, the new unit cost is $1.15 - $0.25 = $0.90 per pound.
The new equation to determine the total cost for p pounds of candy is:
c = 0.90p
Answer:
x = 7
Step-by-step explanation:
3x - 17 = 25 - 3x
Get the x's on one side and the integers on the other
3x + 3x = 25 + 17
6x = 42
x = 7
Answer:
(2, -3)
Step-by-step explanation:
Compare the given (x-2)2+(y+3)2=9 to the standard equation
(x - h)^2 + (y - k)^2 = r^2.
It becomes obvious that h = 2, k = -3 and r = 3.
The center of this circle is (h, k): (2, -3).
Im assuming the entire room would be 9by9ft for the square walls and 20by9ft for the rectangle walls so you would do 9×9+20×9 which is 81+280= 216ft so she doesnt have enough paint
