For what values of k the relation R:{(k2 , 5), (3k, 6)} is not a function?

n200080 [17]

<h3>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.

55% of what number is 22?

Ilya [14]

Answer:
The number is 40

Explanation:
Assume that the number we are looking for is x.
We know that 55% of the number x is 22.
This means that:
55% of x = 22
55% * x = 22
0.55x = 22

Now, we will simply solve for x as follows:
0.55x = 22
x = $\frac{22}{0.55}$ 
x = 40

Hope this helps :)
