Find coordinates of the image of the point A(3,9) for a dilation with the scale factor of 2/3
tiny-mole [99]

Answer:

The coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be: A'(2, 6)

Step-by-step explanation:

Given the point A with the vertices (3, 9) i.e. A(3,9)

As we know that If the scale factor is between 0 and 1, the image gets shrunk.

In order to dilation with a scale factor of 2/3, just multiply the x and y coordinates of the original point (3, 9) by 2/3.

i.e.

(x, y) → (2/3 x, 2/3 y)

so, the coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be:

A (x, y) → (2/3 x, 2/3 y) = A (2/3 (3), 2/3 (9)) = A'(2, 6)

Therefore, the coordinates of the image of point A(3,9) for dilation with the scale factor of 2/3 will be: A'(2, 6)

I need to factor 2x squared plus 6X minus 80
hjlf
2x*2 + 6x + 80

First we have to use distribution property

2(x*2 + 3x + 40)=0
Divide 2 to both sides

X*2 + 3x + 40=0

Multiply -1
-x*2 -3x-40=0
Add two numbers to get 3x
Multiply same two numbers that you add to get 40x*2

Add
-8x+5x= -3x


Multiply
-8x . 5x= -40x*2


-x*2-8x+5x-40

(X*2-8x) + (5x-40)

X(x-8)+ 5(X-8)

Common factor

(X-8)(x+5)

Which one is the answer??
BARSIC [14]

Answer:

B

Step-by-step explanation:

City X = 3 * 10^5            Given

City Y = 6 * 10^6

Times larger

6 * 10^6

3 * 10^5

Do the division

6*10^6/3^10^5 = 60 * 10^5/(3 * 10^5)   Note 10^5 will cancel

60/3 = 20 City y is 20 times City x

Population Difference

6,000,000

   300,000

5,700,000

Just from the numbers I've given you, A is incorrect. The answer is 20 not 2.

B is the answer

C is wrong. X is 5.7 million less.

D See the answer for C.

Answer:
115.2 other solutions is 576/5, 115 1/5
Step by step explanation:
To divide by a fraction, multiply by the reciprocal of the fraction
2.4 x (12 x 4)
Then multiply 12 and 4 which is 48
2.4 x 48
Then multiply 2.4 x 48
which is 115.2
