under a dilation, the point (2,6) is moved to (6,18) what is the scale factor of the dilation? enter your answer in the box

Anestetic [448]

<h2>3</h2>

Step-by-step explanation:

The equation of line passing through the two points is $\frac{y-y_{1} }{x-x_{1} }=\frac{y_{2} -y_{1}}{x_{2} -x_{1}}$

When substituted,the equation becomes $\frac{y-6}{x-2}=\frac{18-6}{6-2}$

which when simplified is $y=3\times x$

The line clearly passes through origin.

The distance between two points is $\sqrt{(y_{1}-y_{2} )^{2}+(x_{1}- x_{2} )^{2}}$

Distance between origin and $(2,6)$ is $\sqrt{40}$ .

Distance between origin and $(6,18)$ is $\sqrt{360}$

Scale factor is $\frac{distance\text{ }of\text{ }p_{2}\text{ from origin}}{distance \text{ } of \text{ } p_{1}\text{ from origin}}$

So,scale factor is $\frac{\sqrt{360} }{\sqrt{40} }$

which when simplified becomes 3.

Simplify the product (x-4)(x+3)

Kamila [148]

Answer:

Final answer is $x^2-x-12$ .

Step-by-step explanation:

Given expression is $\left(x-4\right)\left(x+3\right)$ .

Now we need to find the product of the given expression $\left(x-4\right)\left(x+3\right)$ .

$\left(x-4\right)\left(x+3\right)$

$=x\left(x-4\right)+3\left(x-4\right)$

$=x^2-4x+3x-12$

combine like terms

$=x^2-1x-12$

$=x^2-x-12$

Hence final answer is $x^2-x-12$ .
