Answer:
GIVEN :
Patti is using mental math to evaluate the expression (70 + 12.8 + 30) + 6.1
TO FIND :
The properties of operations allow Patti to simplify.
SOLUTION :
Given that Patti is using mental math to evaluate the expression (70 + 12.8 + 30) + 6.1.
Option d) She can use the commutative property to rewrite the expression as (70 + 30 + 12.8) + 6.1 is correct.
For :
Patti's expression is (70 + 12.8 + 30) + 6.1
By using the commutative property of addition
a+b=b+a
(70 + 12.8 + 30) + 6.1
= (70+30+12.8)+6.1 (here a=12.8 and b=30)
∴ the properties of operations allow Patti to take is the commutative property of addition.

I hope this helps btw try studying if you dont know how to do this.
Answer:
K(1,0), L(2, 3), M(-1, 4), N(-2,1)
Step-by-step explanation:
Because the points are being flipped over the x-axis the y values remain the same, but the x values are multiplied by -1. Multiplying the values by -1 will switch a negative value positive and a positive value negative. This will correctly flip the points to the opposite side of the graph.
