Question

1. The name of an algebraic property and an example are given. Which one is incorrect?
    Associative Property: 5 + (1 + 7) = (5 + 1) + 7
    Commutative Property of Addition: 4 + (2 + 3) = 4 + (3 + 2) 
    Distributive Property: -2(x - 6) = 2x + 12 
    Inverse Property of Addition: -3 + 3 = 0

2. Change y = 3(2 - 2x) into standard form

3. what expression would represent "twice the perimeter of a rectangle", if x = the width and y = the length?

4. Where is the vertex of y = |3x - 6| + 3

5. What is the slope of the line perpendicular to the line. y= -4/5x + 1

6. Twice the sum of two consecutive even integers is 260. Find the integers

7. Solve: 7x + 5 = - x - 11 

Thanks alot!!!!!!!!!

Hint: #7 convert the problem to equal to zero and solve for x.
#6 hint: twice means two times X and two times y equals 260 and solve.
#2 look at your standard form format in your math book and covert your problem.
#3 perimeter is the sum of all sides of a rectangle. Perimeter is 2 times 2x + 2Y.
#4 look at your book and search for the formulas for find ing vertex
And #1 look at the definition of each in your book and see which one does not match

Good luck with your homework kid!
