Abcd is a parallelogram find ab and bx.
Olin [163]
In a parallelogram, opposite sides have the same length. 
3x + 9 = 5x -5
group like terms on one side
9 + 5 = 5x -3x
14 = 2x
x is 7.
Since AB is 5x -5 
AB = 5(7) -5
AB = 30.

BX is half of the line DB. So BX = DX
5y = 7y - 10
10 = 7y -5y
10 = 2y
y =5.
Since BX = 7y - 10
BX = 7(5) -10
BX = 25

Slope=2/3;y-intercept=-1 write the linear equation in slope -intercept form
Mnenie [13.5K]

Answer:

\large\boxed{y=\dfrac{2}{3}x-1}

Step-by-step explanation:

The slope-intercept form of an equation of a line:

y=mx+b

<em>m</em><em> - slope</em>

<em>b</em><em> - y-intercept</em>

<em />

We have the slope \bold{m=\dfrac{2}{3}}, and the y-intercept <em>b = -1.</em>

Substitute:

y=\dfrac{2}{3}x-1

How do I go about solving this?
Stels [109]
Hello,

Here i am using vectors

\vec{AB}=\vec{DC}=3\vec{i}+3\vec{j}
==> AB//DC and AD//BC (definition of a translation)


The quadrilater ABCD is a parallelogram:
so
1) his diagonals have the same length;

2) his diagonals are cutting in the middle.

(these are proprieties of a parallelogram)
