<h2>Answer = </h2><h2>=  \frac{1}{y {}^{5} x {}^{2} }</h2>

Step-by-step explanation:

Greetings !

simplify for variable y first

apply exponent rule

a {}^{b} .a {}^{c}  = a {}^{b +c \\   } \\  y {}^{ - 8}y {}^{5}  = y {}^{ - 8 + 3}

Add/subtract the numbers -8+3=5

= y {}^{5}

Apply exponent rule

a {}^{ - b}  =  \frac{1}{a {}^{b} }

Thus,

y {}^{ - 5}  =  \frac{1}{y {}^{5} }

secondly, simplify for the variable x

Apply exponent rule as we made on y

x {}^{ - 2}

x  {}^{ - 2}  =  \frac{1}{x {}^{2} }

multiply bot the values we get

Hope it helps!

find the scale, k, of H(3,4) if H'(9,12) after going through the transformation (x,y) ---&gt; (kx,ky) centered at the origin
stiks02 [169]

The value of scale k is 3

Step-by-step explanation:

In order to find the scale , we can either divide the coordinates of H' by the original point or compare both the points to find the original ordered pair.

Given

H(3,4)

H'(9,12)

The coordinates of H are multiplied with some integer k to form H'

So,

<u>For x-coordinate:</u>

3k = 9

k = 9/3 = 3

<u>For y-coordinate:</u>

4k = 12

k = 12/4 = 3

Hence,

The value of scale k is 3

Keywords: Coordinate geometry, scaling
