Answer:
D
Step-by-step explanation:
A) This has a y intercept at (0,0) so this is True
B) True
C) True
D) This is NOT true. The degree of the numerator and denominator are the same. This graph looks like the function of 
Answer: 94.5
Step-by-step explanation:
9/2 × 21/4
Get common denominator
9 × 2 =18
2 × 2 = 4
18/4 × 21/4
21 × 18 = 378
378/4 = 94.5
Answer: 16 observations

Answer:f(x) = 80x + 65f
Step-by-step explanation:
Since x = days and y = total rent, you've been given two points on your function: (5, 465) and (7, 625). We'll find the slope using those two points:
(625 - 465) / (7 - 5) = 160/2 = 80
Then, use m = 80 and one of the points to write the equation of your line in point-slope form:
y - y1 = m(x - x1)
y - 465 = 80(x - 5)
Convert that to standard form:
y = 80(x - 5) + 465
y = 80x - 400 + 465
y = 80x + 65
y - 80x = 65
In function notation, that's:
f(x) = 80x + 65
