Answer:
I dont understand? What is the question you are asking? Did you mean to add a photo?
Step-by-step explanation:
Y = 3x^2 + 7 is the equation of the parabola
When we say "closed under addition" in the context of rational numbers, we mean to say that when we add up rational numbers then, the sum is also a rational number.
From the given choices above, the one that should the characteristic of being "closed under addition" is only fourth equation. Both 1/2 and 0.5 are rational numbers. On the other hand, 1 is also a rational number.
The answer is : f= -0.14467690+k\1888
We know that A and F are also both parallel.
This is because the transitive property applies to parallel lines. So if A and C are parallel and C and F are as well, it means that A and F must also be parallel.
