The correct answer is d. 9 + 0 = 9
Further explanation:
If x is an element of a set, and adding a number to it doesn't change it i.e. the result is also x then the number is called additive identity.
In mathematics, 0 is considered as additive identity because no matter with which number it is added, the number always remains same.
In the given options:
Option a. 5*1=5 demonstrates multiplicative identity
Option b. 3+5=5+3 demonstrates commutative property
Option c. 4+ (6 + 8) = (4+6) +8 demonstrates associative property
While the last option
d. 9 + 0 = 9 demonstrates additive identity as zero is being added to 9 and the answer is also 9.
The correct answer is d. 9 + 0 = 9

Answer:
b i think
Step-by-step explanation:
Answer:
y = 3x - 9
Step-by-step explanation:
First, find the slope using rise/run (y2 - y1) / (x2 - x1)
Plug in the points:
(36 - 21) / (15 - 10)
15/5
= 3
Next, plug the slope and a point into the equation y = mx + b to find b (y-int)
y = mx + b
21 = 3(10) + b
21 = 30 + b
-9 = b
Then, plug this into the equation, as well as the slope:
y = 3x - 9
