Answer: Choice A) y = cx
The 'c' is the constant of variation
For example, if c = 2, then y = 2x is a direct variation. Whatever x is, we double it to get y. As x increases, so does y. As x decreases, then so does y. Both x and y increase/decrease together.
Direct variation equations always go through the origin, and they are always linear. The 'c' plays the role of the slope. You can think of y = cx as y = mx+b where b = 0 in this case and c = m.
Answer:
O C. 0
Step-by-step explanation:
What is the sum of 15 and its additive inverse?
In Mathematics, the additive inverse of a number is defined as the number that when it is added to a specific number equals 0
From the above question, the additive of 15 = -15
Therefore, the sum of 15 and its additive inverse is calculated as:
15 + -15
= 15 - 15
= 0
Therefore, Option C is the correct option
The area of one of the triangular lateral faces is

You're told that the slant height, which is the same as the height of the triangular face, is 9.8, so you have

where

is the length of the base of the triangle, which is also the same as the side length of the base of the pyramid. So
Answer:
We have two cases.
Step-by-step explanation:
A proof by Induction consists of two cases, the base case (or basis) and the induction step. Induction is a style of argument we use to convince ourselves and others that a mathematical statement is always true. Many mathematical statements can be proven by simply explaining what they mean.
