Answer:
Step-by-step explanation:
- The pyramid of Khafre measured 143.5 meters high.
- The pyramid of Menkaure measured 65.5 meters high.
<u>The difference in the heights of the two pyramids:</u>
- d = 143.5 m - 65.5 m
- d = 78 m
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)
I think this is the answer if you follow the order of operations. X=12
