Answer:
D
Step-by-step explanation:
you want to solve it out
start with multiplying z to each. you don't multiply it to the 6 because it is in the same parenthesis set, but you multiply it to everything in the other set. After multiplying, you get: ,
,
now do that to the 6. After multiplying you get: ,
,
now set it all next to each other +
+
+
+
+
now combine like terms. start with the to the highest power. since there is only one that has a third power, you put that one first. then you combine the squared ones, and so forth.
work combining the squares:
work combing the single z's:
to get this: +
+
+
so, the answer is D
Answer:
K=6
Step-by-step explanation:
we know that
A function is: a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output
so
In this problem
If the x-coordinate of the first point is equal to the x-coordinate of the second point, then the relation will not be a function
Remember that the x-coordinate is the input value and the y-coordinate is the output value
Equate the x-coordinates and solve for k
therefore
If the value of k is 6 the, the relation will not be a function
