Answer:
right the whole question
Step-by-step explanation:
if he sold 32 items this week last week he sold 20
a
x 0.5x + 10 y
0 0.5(0) +10 = 10 (0,10) the y intercept
1 0.5(1) + 10 = 10.5 (1, 10.5)
4 0.5(4) + 10 = 12 (4, 12)
5 0.5(5) + 10 = 12.5 (5, 12.5)
6 0.5(6) + 10 = 13 (6, 13)
b
see attached graph
c
Since they add ten for each call before they multiple miles it is not proportional.
d.
No because the graph shows negative numbers and presumably the company can't charge you if they don't drive there.
Answer:
about 0.0927 seconds
Step-by-step explanation:
Put the given information into the given formula and solve for the remaining variable. It is a linear equation, solved in the usual way.
ln(0.430/0.750) = -7.50t/1.25 . . . substitute the given information
-ln(43/75)/6 = t ≈ 0.092714 . . . . . divide by the coefficient of t
Rounded to 3 significant figures, the time is 0.0927 seconds.
