Rasek [7]

A quadrilateral is said to be a parallelogram

1.Opposite sides are equal and parallel.

2. Diagonal bisect each other.

3. Opposite angles are equal.

It is given that , a Parrallelogram is graphed on a coordinate plane so the two points are in the first quadrant and two points are in the third quadrant.

Suppose ABCD is a Parallelogram.Then AB=CD and AD=BC.

Given, Vertices A,B lies in first Quadrant and Vertices C and D lies in Third Quadrant.Then Vertices of Parallelogram ABCD are

A=( x, y) and B=( y, x)

Then, C= (- x,- y) and D= (- y,- x), Arranged in Alphabetical order, that is A,B and C and D.

3(3−3)=2(+3)−30 how do I do this???? I'm in 10th grade and this confuses me every time.

astra-53 [7]

Well when you simplify it you get this,

0=-24,

Do what’s inside the parentheses first

3-3 is 0, 3•0 is 0

2•positive 3 is 6

6- -30 is -24

So you have 0=-24

Or just -24 :)

An electrician charges $35 per hour plus a fixed amount for residential work. For a job that took 6 hours, he billed $270. Write

Alexeev081 [22]

With the information provided, we can begin with the equation:

y=35x + b

With x = number of hours, y = total cost, b = fixed amount that is charged for residential work

We know that after 6 hours, $270 was charged:

$270 = $35(6) + b

Solve for b:

b = $270 - $210 = $60

The fixed amount that is charged for residential work is $60. So now we can rewrite the equation as:

y = 35x + 60
