Answer: k = 0 or k = 3</h3>
Explanation:
If you have repeated x values, then you wont have a function. For example, the points (1,5) and (1,6) mean we don't have a function since the input x = 1 leads to multiple outputs y = 5 and y = 6 simultaneously. For a function to be possible, we must have any input lead to exactly one output only.
What we do is set the x coordinates (k^2 and 3k) equal to each other and solve for k
k^2 = 3k
k^2-3k = 0
k(k-3) = 0 .... factoring
k = 0 or k-3 = 0 .... zero product property
k = 0 or k = 3
If k = 0, then (k^2,5) becomes (0,5). Also, (3k,6) becomes (0,6). The two points (0,5) and (0,6) mean the graph fails the vertical line test.
Similarly, if k = 3, then (k^2,5) becomes (9,5) and (3k,6) = (9,6). Another vertical line test failure happens here to show we don't have a function.
The answer is -177

Answer:
On the first one, multiply 6 by 3 (18) and subtract from 27 = $11
Step-by-step explanation:
$11 divided by three
About $3.66 Per day. I don't know how to do those graphs you doin but that's the answer to the question itself. Hope I helped?
The second one:
Divide 77 by 7 days (11)
Then subtract 4 from that (which gives you 7) because you need to know how much water is used on the flowers, not the shrubs. So, the answer should be 7. Correct me if I'm wrong, people.
