Answer:

  • Commutative Property of Addition.-  
  • 2 + 3 = 3 + 2
  •  Commutative Property of Multiplication.- ex. 5 × 7 = 7 × 5  
  • Associative Property of Addition.- ex.(2 + 3) + 6 = 2 + (3 + 6)  
  • Associative Property of Multiplication.- ex. (7 × 3) × 10 = 7 × (3 × 10)
  • Distributive Properties of Addition Over Multiplication- ex. 2 × (2 + 8) = 2 × 2 + 2 × 8  
  • (2 + 8) × 10 = 2 × 10 + 8 × 10
  • The reciprocal of a non zero real number a is 1/a.- ex. reciprocal of 5 is 1/5 and 5 × (1/5) = 1

This graph has rotational symmetry about the points
mart [117]

Answer: Answer for figure one is origin (0,0)

Answer for figure two is (2,4) /

Step-by-step explanation:

a) Here we can see that given graph is the equation of cubic function which is

f(-x) = -f(x) that is given function is odd then rotational symmetry point is origin always ,therefore point of rotational symmetry is origin (0,0)

b) The rotational symmetry of  an ellipse is 180 degrees about the center  of  the ellipse .

And here the center of given ellipse is  (2,4) ,therefore its rotational  symmetry is about (2,4) That is if we rotate the given ellipse 180 degrees about (2,4) it will be at its original position.

How to solve 5/6y + 1 = -1/2y + 1/4
True [87]

Answer:

y= -1/4

y= -0.25

Step-by-step explanation:

5/6y+1= -1/2y+1/4

<em>Subtract 1 from both sides</em>

5/6y= -1/2y-3/4

<em>Add 1/2y to both sides</em>

1 1/3y= -3/4

<em>Divide both sides by 1/3</em>

y= -1/4

y= -0.25
