Q1. Look at the picture.

Q2. Look at the picture.

Q3.
Put the value of x = 2 to the equation 3x + y = 5:

<em>subtract 6 from both sides</em>

Q4.

Substitute (*) to (**):
<em>use distributive property</em>

<em>add 33 to both sides</em>
<em>divide both sides by 11</em>

Put the value of m to (*):


Q5.
w - width
3w - length
24 in - the sum of length and width
The equation:

<em>divide both sides by 4</em>



Answer:
-4,2
Step-by-step explanation:
a reflection across the y axis means the y values stay the same and the x values change sign
A rhombus is quadrilateral where all 4 sides are of equal length. Thus
5x + 2 = 2x + 12
3x = 10
x = 10/3
substituting x into either expression, yields
56/3
therefore side AB = 56/3
