Part A:
The given values in form of ordered pairs are:
(2,1), (3,1), (4,-3), (3,-3)
A relation can be a function if one value of x is paired with exactly one value of y. In this case, x value of 3 is paired with two y values 1 and -3. So this relation is not a function.
Part B:
f(h) = 15h + 5
f(8) can be found by substituting h=8 in above equation.
So,
f(8) = 15(8) + 5 = 125
h represents the number of hours and f(h) represents the earnings of Kylie. So f(8) shows that Kylie earned $125 from 8 hours of work in the cafe
Part C:
For r hours of work, we can write:
f(r) = 15r + 5
So, the ordered pair can represent this relation as:
(r, f(r))
or
(r, 15r+5)
The solution would be like
this for this specific problem:
<span><span>9 ! </span><span>
<span>------- </span>
<span>6 ! 3! </span>
<span>9 x 8 x 7 </span>
<span>-------------- </span>
<span>6 </span></span></span>
504 / 6 = 84
<span>So the value of 9C6 is <span>84.</span></span>

Answer:
3^5= 3 times 3 times 3 times 3 times 3 or 243
Step-by-step explanation:
Answer:
40%
Step-by-step explanation:
32/80=.4
From 9 P.M. to 5 A.M. the temperature dropped 20°, making the rate over 8 hours, -2.5° Per Hour. By 5 A.M., the temperature is -5° since we had to do 15 - 20. From 5 AM to 5 P.M. is 12 hours so -2.5 x 12 = -30 making 30 how much the temperature dropped between 5 A.M. to 5 P.M. Finally, our last equation is -5 - 30 making -35 our answer.
