Answer:
In Direct Proof
Step-by-step explanation:
Direct Proof is one of the methods, used to prove in maths
Such conclusion is established by logically combining the axioms, definitions & earlier theorems.
Example : To prove - Sum of two even integers is always even
Let a , b be two even integers. If they are even, they can be written as a factor of 2, as a = 2x & b = 2y respectively. Their sum a + b = 2x + 2y = 2 (x+y). So, their sum is also even, as it has a factor of 2. The statement is hence proved by direct method.

the answer is C
Step-by-step explanation:
so you see that it says you want to measures the amount of water
in plain and short, to graph an inequality, we first graph its EQUALITY graph, and then we do the shading.
so to graph y > x + 3, we first graph y = x + 3, which is just a line, and then do a true/false check on a point to see which side we shade.
let's hmmm check the point say (0,2), x = 0, y = 2.
y > x + 3
2 > 0 + 3
2 > 3 <--- is that true? is 2 really larger than 3? nope, so is false.
that simply means that the point (0, 2) is on the false area, so that's the area we do NOT shade, so <u>we shade the other side</u>.
y > x + 3, means "y" is greater than or larger than that line, but not equals, larger not equal, meaning the values on the borderline are not included, so the line is a dashed line.
check the picture below.
