Answer:

The scale factor is the ratio of the length of a side of one figure to the length of the corresponding side of the other figure. Example: Here, XYUV=123=4 . So, the scale factor is 4

Answer:

the scale factor would be 4

Step-by-step explanation:

also

A scale factor is a number which scales, or multiplies, some quantity. In the equation y = Cx, C is the scale factor for x. C is also the coefficient of x, and may be called the constant of proportionality of y to x. For example, doubling distances corresponds to a scale factor of two for distance, while cutting a cake in half results in pieces with a scale factor for volume of one half. The basic equation for it is image over preimage.

branliest please also be sure to comment and i'll help with everything again the scale factor of the attachment given is 4

Pls help me! And explain how you found the answer pls

Dmitriy789 [7]

Answer:

y = $\frac{1}{2}$ x - 3

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Calculate m using the slope formula

m = $\frac{y_{2}-y_{1} }{x_{2}-x_{1} }$

with (x₁, y₁ ) = (- 22, - 14) and (x₂, y₂ ) = (- 18, - 12)

m = $\frac{-12+14}{-18+22}$ = $\frac{2}{4}$ = $\frac{1}{2}$ , thus

y = $\frac{1}{2}$ x + c ← is the partial equation

To find c substitute either of the 2 points into the partial equation

Using (- 18, - 12) , then

- 12 = - 9 + c ⇒ c = - 12 + 9 = - 3

y = $\frac{1}{2}$ x - 3 ← equation of line

I’m confused, please help

kodGreya [7K]

Answer: (a)

Step-by-step explanation:

Given

$g(x)=x^2$

Clearly, $f(x)$ is obtained by shifting $g(x)$ 3 units down and multiplying it by a certain factor to amplify it.

Checking the option which is 3 units below and multiplying by a factor

option (a) is meeting both the cirterias.

If for a particular one-to-one function f(2) = 13, what are the corresponding input and output

maks197457 [2]

Answer:

$f^{-1}(13) = 2$ .

Step-by-step explanation:

For function $f$ , the notation $f(2) = 13$ means that when the input to the function is $2$ , the output would be $13$ .

The inverse function of a one-to-one function $f$ is commonly denoted as $\!f^{-1}$ .

The inverse function undoes the action of the original function. In this question, $f$ maps $2$ to $13$ . Thus, $f^{-1}$ would need to map $13\!$ back to $2\!$ . Therefore, $f^{-1}(13) = 2$ should be the corresponding input and output values.
