Answer:
y = -7.2x + 540
Step-by-step explanation:
to find the slope I used the x-and-y intercepts: (0, 540) and (75, 0)
slope = 540/-75 or -7.2
If there are no repeating x values and an x value only goes to <em>one</em><em> </em>y value, then yes, it is a function.

Answer:
16 square units
Step-by-step explanation:
When you plot the points, you see they define a trapezoid with bases of lengths 2 and 6, and a height of 4. The area formula is ...
A = (1/2)(b1 +b2)h
A = (1/2)(2 +6)(4) = 16
The area of the trapezoid is 16 square units.
The answer to this equation would be 278.135
Answer: 12.60 per CD
Step-by-step explanation:
Tax 0.80 * 3 = 2.40
