Answer:
<h3>Part A</h3>
- <em>The graph is attached</em>
<h3>Part B</h3>
For zero number the cost is zero and the rate of change is 25.
- 0 - 0, 1 - 25, 2 - 50, 3 - 75, 4 - 100
This is the indication of the proportional relationship
<h3>Part C</h3>
- It is a constant change as the difference is same for each step - 25
- The ordered pair (1, 25) shows the unit rate is $25 per pair of shoes
<h3>Part D</h3>
- Constant of proportionality is 25
<h3>Part E</h3>
<u>The equation is:</u>
where y - cost, x - number of pairs of shoes, 25 - constant of proportionality
hello :
<span> y = x2 + 3x -3.... (1)
2x - 1 = y ..........(2)
subsct in (1) :
2x-1 = x² +3x -3
x² + x -2 = 0
(x+2 )(x-1 ) = 0
x+2=0 or x-1 = 0
x=-2 or x=1
if : x = -2 y = 2(-2)-1 =-2
if : x = 1 y = 2(1)-1 = 1
</span><span>values of x will (x, y) be a solution of the system : (-2,-2),(1,1)</span>
