Answer:
inverse variation
Step-by-step explanation:
the numbers equal but then have to be devided
For this case we have the following system of equations:

We multiply the second equation by -3:

Thus, we observe that the second equation is equivalent to the first, if we add both we get:

The equality is fulfilled. The lines are on top of each other.
Answer:
Infinite solutions
Answer:
No
Step-by-step explanation:
This is because when a triangle has side lengths a,b, and c, a+b>c.
But 6.0+4.2 is not greater than 12.2, so this not a triangle.
Answer:
B) >
Step-by-step explanation:
You can compare fractions by converting them into a decimal and examining which one has the greater value.
3/4 = 0.75
3/5 = 0.6
From this, we can see that 3/4 is greater than 3/5, so the sign will be >.
----
note: You can also find the least common denomiator between the fractions and compare their numerator values to find which one is bigger. The one with the larger numerator will be the greater fraction.
hope this helps!
