Answer:
The horizontal line test may be used to determine whether a function is one-to-one.
The vertical line test may be used to determine whether a relation is a function.
Step-by-step explanation:
First, multiply the top equation by 2 and bottom by -3.
60x+60y=900
-60x-75y=-1035
————————
-15y=-135
—————-
-15=-15
y=9
So the answer should be 9.
Is that the full question, because it doesn't make sense to me :/
0.4335/1 x 10000/10000
=4335/10000
=867/2000
