To say that n is at least 4 is to say that n is 4 or greater than 4.
As symbols, that is written as this: n ≥ 4
This would be communicative property cause when solve the left side then the right they both come up to being 30=30.
Answer:
a = 5
b = -4
c = -20
Step-by-step explanation:
Here, we want to express the given equation in the following form;
So we can have this as;
5x-4y-20 = 0
That means we have;
a as 5
b as -4
and c as -20
