True lol yea I totally just didn’t randomly guess haha.
Which of the sets of ordered pairs represents a function? A = {(1, −5), (8, −5), (8, 7), (2, 9)} B = {(7, −4), (7, −2), (6, −3),

Answer:
Neither A or B
Step-by-step explanation:
Hello There!
In order for a set of ordered pairs to represent a function none of the x values can repeat
In answer choice A the x value 7 repeats therefore the set of ordered pairs do not represent a function
In answer choice B the x value 7 repeats therefore the set of ordered pairs do not represent a function
so we can conclude that neither set of ordered pairs represent a function
X^2+6x+9=0
(x+3)(x+3)=0
x=-3 There is only one unique way.
Answer:
21
Step-by-step explanation:
It is given that y varies inversely with x.
...(i)
where, k is constant of proportionality.
It is given that x=-3 when y=-105. Substitute these values in equation (i), to find the value of k.
Now,
Substitute x=15 in the above equation.
Therefore, the value of y is 21 when x=15.
