A geometric figure is dilated by a scale factor of 4/3with the origin as the center
of dilation. Which of the following algebraic representations best describes the
dilation?

Answers

Answer 1

Answer: Scale Factor (Dilation) The scale factor in the dilation of a mathematical object determines how much larger or smaller the image will be (compared to the original object). When the absolute value of the scale factor is greater than one, an expansion occurs.

Step-by-step explanation:

A dilation is a transformation that produces an image that is the same shape as the original, but is a different size.

Answers

Answer:

h=11

Step-by-step explanation:

12h-33=99

12h-33+33=99+33

12h=99+33

12h= 132

12h/12=132/12

h=11

h equals 11.
(the reciprocal) so add 33 to both sides.
99+33=132
12h=132
divide 12 by both sides & thats gives you 11.

An equation and the first step in its solution are shown.

Equation: x2 + 3x – 9 = 0

Step 1: x2 + 3x + h = 9 + h



What value of h is used to solve the equation by the method of completing the square?

Answers

Answer:

The answer is either 1.5 or 0.667

Step-by-step explanation:

x2+3x-9=0

x2+3x=9

6x=9

x=1.5

or

x=667

the value of 'h' used to solve the equation by completing the square method is [tex]\frac{9}{4}[/tex]

Given :

An equation and the first step in its solution are shown.

Equation: [tex]x^2 + 3x -9 = 0[/tex]

Step 1: [tex]x^2 + 3x + h = 9 + h[/tex]

In completing the square method , we take the coefficient of x  and divide it by 2  and then square it

coefficient of x is 3

divide it by 2 , so we get [tex]\frac{3}{2}[/tex]

Then we square it [tex](\frac{3}{2} )^2\\\frac{9}{4}[/tex]

Then we add it on both sides of the equation

[tex]x^2 + 3x + \frac{9}{4} = 9 + \frac{9}{4}[/tex]

So, the value of 'h' used to solve the equation by completing the square method is [tex]\frac{9}{4}[/tex]
