How so you write numbers in a expanded

Mathematics

yan [13]3 years ago

To write numbers in expanded form, you just break it down.
For example: 5,522 This in expanded form is 5,000+500+20+2
Basically, you just take the number and place zeros the number of times the numbers are behind. Does this make sense?
If you have any questions, you can always ask me.

Hope this helps

Could someone help me? Which color is it.
wariber [46]

Answer:

(1,3)

Step-by-step explanation:

y = 2x+1

y = 4x-1

Since both equations are equal to y, we can set them equal to each other

2x+1 = 4x-1

Subtract 2x from each side

2x+1-2x = 4x-2x-1

1 = 2x-1

Add 1 to each side

1+1 = 2x-1+1

2 = 2x

Divide each side by 2

2/2 = 2x/2

1 =x

Now we need to find y

y = 2x+1

y = 2(1)+1

y =3

How many feet does a car travelling at 65 MPH go in one second ?
Semenov [28]

Answer:

At 65 mph, keeping one second of following distance means the vehicle is traveling 100 feet behind the vehicle in front. It takes an automobile a minimum of 150 feet to stop. With a 100 foot gap plus the auto's stopping distance of 150 feet, an impact would occur within 250 feet.

Write the equation of a parabola having the vertex (1, −2) and containing the point (3, 6) in vertex form. Then, rewrite the equ
In-s [12.5K]
PART A

The equation of the parabola in vertex form is given by the formula,

y - k = a {(x - h)}^{2}

where

(h,k)=(1,-2)

is the vertex of the parabola.

We substitute these values to obtain,


y  + 2 = a {(x - 1)}^{2}

The point, (3,6) lies on the parabola.

It must therefore satisfy its equation.


6  + 2 = a {(3 - 1)}^{2}


8= a {(2)}^{2}


8=4a


a = 2
Hence the equation of the parabola in vertex form is


y  + 2 = 2 {(x - 1)}^{2}


PART B

To obtain the equation of the parabola in standard form, we expand the vertex form of the equation.

y  + 2 = 2{(x - 1)}^{2}

This implies that

y + 2 = 2(x - 1)(x - 1)


We expand to obtain,


y + 2 = 2( {x}^{2}  - 2x + 1)


This will give us,


y + 2 = 2 {x}^{2}  - 4x + 2


y =  {x}^{2}  - 4x

This equation is now in the form,

y = a {x}^{2}  + bx + c
where

a=1,b=-4,c=0

This is the standard form
