Answer:

Associative property of addition

Step-by-step explanation:

The associative property of addition is as follows :

a+(b+c) = (a+b)+c

We have,

a = 8, b = 9 and c = 3

So,

Using above property,

(8+9)+3 = 8+(9+3)

20 = 20

Hence, this is the required solution.

Sonja [21]

The first one is greater. Adding 3.2 and 0.2 is easy! It's 3.4! Make that 3. Make 6.9, 7. 7×3=21. For the first one, make 1.9, 2. Then Make 3.15, 3. 5×5=25. That is why the first one is greater.

VikaD [51]

Let's use the slope-intercept equation:

$\begin{gathered} y=mx+b \\ m=slope \\ b=y-intercept \\ x-intercept=a \\ x=\frac{y-b}{m} \\ x=\frac{y}{m}-\frac{b}{m} \\ x=\frac{y}{m}-a \\ or \\ y=mx+ma=m(x+a) \end{gathered}$

------------------------------------

$\begin{gathered} y=mx+b \\ m=slope=\theta \\ b=y-intercept \\ y=\theta x+b \\ \end{gathered}$
