Answer:
Step-by-step explanation:
A linear equation, when graphed, gives a straight line. This looks like you meant y=3x^3 - 3
There are parts of this equation that look like they could be linear, but the graph below shows that the graph does not go straight through -3. The graph therefore is non-linear.
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
1.TR is the two equations combined so 18x+26
Sqrt (y^4 * y)
Sqrt y*4 = y^2
y^2 sqrt y
You switch the sign of the y coordinate for point b, so the new b coordinate is (-2,1)
