For this case we have the following ordered pairs:
 (6, 9)
 (4, 6)
 The scale factor can be found in two different ways:
 k = 6/4 = 3/2 = 1.5

k = 9/6 = 3/2 = 1.5
 Therefore, the scale factor is given by:
 k = 1.5

 Answer:
 
The scale factor of the dilation is 1.5

Answer:

2/3.

Step-by-step explanation:

The exercise says us that we multiply (6,9) by a factor (in the enunciated is called a dilation) and obtain (4,6). That is

(6,9)x=(6x,9x) = (4,6). (in the exercise the x is represented with a0)

Now, one ordered pair is equal to another if both first components are equal and also if both second components are equal. Then,

6x = 4 and 9x=6

x = 4/6 and x = 6/9

x = 2/3 and x= 2/3.

So, the scale factor of the dilation is 2/3.

The price of a new car is $42,500. If the sales tax rate is 6%, what is the total cost for the car including tax?
ozzi

Answer: $45,050

Step-by-step explanation:

First we multipy 0.06 (6%) by 42,500

$42,500 * 0.06 = $2550

This is the tax that must be applied to $42,500

Now all we need to do is add $2,550to $42,500 and we get:

$42,500 + $2,550 = $45,050

Find ( f - g)(x).<br><br> f (x) = -2x2 - 2x - 3 and g(x) = 3x2 - 4x - 4
Kruka [31]

Answer:

\large\boxed{(f-g)(x)=-5x^2+2x+1}

Step-by-step explanation:

(f-g)(x)=f(x)-g(x)\\\\\text{We have}\ f(x)=-2x^2-2x-3\ \text{and}\ g(x)=3x^2-4x-4.\\\\\text{Substitute:}\\\\(f-g)(x)=(-2x^2-2x-3)-(3x^2-4x-4)\\\\(f-g)(x)=-2x^2-2x-3-3x^2+4x+4\qquad\text{combine like terms}\\\\(f-g)(x)=(-2x^2-3x^2)+(-2x+4x)+(-3+4)\\\\(f-g)(x)=-5x^2+2x+1
