Which of the following is an example of the Symmetric Property of Equality?

Question

5 + x = x + 5

7(1) = 7

If 2x+3 = 10, then 10 = 2x+3

If x+4 = y and y=3x, then x+4 =3x

Which set of ordered pairs is a function?

(1,2), (2,2), (4,5), (1,-4)

(3,4),(5,1)(6,3),(6,4)

(7,5),(3,2),(-5,10), (-1,-2)

(2,3), (-1,3),(4,8),(2,0)

Is the following set of ordered pairs a function?

(4,5),(3,4),(-2,5),(6,-8),(5,1)

Yes

No

Evaluate the function f(x) = 3x + 1 when x=2.

Evaluate the function g(x) = -2x + 4 when x=-1.

Which of the following represents the statement: 4 more than three times a number is 12.

3(4) + x = 12

4 + 3x = 12

3x -4 = 12

4> 3x + 12

Solve the following equation for b: A=1/2BH

Answer 1

Symmetric Property says if a =b then b=a.

So answeer is If 2x+3 = 10, then 10 = 2x+3

(7,5),(3,2),(-5,10), (-1,-2)

Yes

3*2+1 = 6+1=7

-2(-1) +4 = 2+4 = 6

4 + 3x = 12

2A = BH --> b= 2A/H

Answer 2

1)  5 + x = x + 5

2) (7,5),(3,2),(-5,10), (-1,-2)

3) yes

4) 7

5) 6

6) 4 + 3x = 12

7) B = 2A / H
