Answer:
Step-by-step explanation:
The rule that makes a relation NOT a function is if there are shared x values. This function has 2 points with the same x value:
(7, 4) and (7, 6). The sharing of these x-values (or the repeating of them) within the same relation makes this NOT a function. The last choice is the one you want. Just remember that a relation is only a function if there are no shared x-values. The y-values don't matter to this at all. A relation would be a function if it were made up of the following coordinates:
(1, 2), (2, 2), (3, 2), (4, 2), (5, 2), etc. Again, as long as the x-values don't repeat, the relation is a function.
It is CONSTANT if the graph is of a horizontal line.
It is LINEAR if the graph is of a line that is not horizontal.
It is NONLINEAR if it is a function that is neither linear nor constant.
Answer:
I think the answer is A, 70 square centimeters
I believe the answer is 1.343 x 10^5
Answer:
$75
Step-by-step explanation:
let the original price be x
then,
80% of x = 60
80/100 of x = 60
therefore x = 75
