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 greatest common factor would be xy^2 because these are the only factors that they all have in common. The second term only has 1 x, so only 1 x is part of the gcf.
The 1st and 3rd terms each have y^2 therefore making it part of the gcf as well.
3v + 2 = 7v
2 = 4v
1/2 = v
QS = 3v + 2
= 3(1/2)+ 2
= 1.5 + 2
= 3.5
TV = 7v
= 7(1/2)
= 3.5
