Answer:

13.5=k

Step-by-step explanation:

When 2 triangles are similar the ratio of their corresponding sides are equal.

$\frac{XY}{YZ}=\frac{AB}{BC}\\\\$

Plug in the values given:

$\frac{4.5}{3} =\frac{k}{9}$

Cross Multiply

40.5=3k

Divide to isolate k

13.5=k

Therefore, (6-7/7) x 100% = 14.3%

Which phrase best describes the translation from the graph y=(x-5)^2+7 to the graph of y=(x+1)^2-2

Helga [31]

Start from the parent function $f(x)=x^2$

In the first case, you are computing

$f(x-5)+7$

In the second case, you are computing

$f(x+1)-2 /tex] There are two translation going on: when you transform [tex] f(x) \to f(x+k)$ , you translate the function horizontally, $k$ units left if $k>0$ and $k$ units right if $k$ .

On the other hand, when you transform $f(x) \to f(x)+k$ , you translate the function vertically, $k$ units up if $k>0$ and $k$ units down if $k$ .

So, the first function is the "original" parabola $f(x)=x^2$ , translated $5$ units right and $7$ units up. Likewise, the second function is the "original" parabola $f(x)=x^2$ , translated $1$ units left and $2$ units down.
