The associative property is the answer
Answer:
B and C
Step-by-step explanation:
In order to know your x and y intercept, first rearrange your equation in the form ax+by=c
<u>NB </u> c should always be one so if you rearrange and c is not one, divide the whole equation by the no. represented by c, then to know your x and y intercepts look at the reciprocal of the coefficients of x and y
For example
B. -4x+2y= -6
divide the whole equation by -6 to get
2/3x-1/3y=1
hence the x intercept will be the reciprocal of the coefficient of x which is 3/2
y intercept will be the reciprocal of the coefficient of y which is -3
so if you look at the line, the equation applies
The same will apply to C

Volume of a Cuboid Formula: V = a²h
- <em>a</em> is the sides of the cube
- <em>h</em> is the height
Step-by-step explanation:
<u>Step 1: Define</u>
<em>Identify variables</em>
<em>a</em> = 3
<em>h</em> = <em>h</em>
<em />
<u>Step 2: Find Volume</u>
- Substitute in variables [Volume of a Cuboid Formula]: V = 3²h
- Evaluate exponents: V = 9h
