Answer:

\frac{3}{4}

Step-by-step explanation:

To determine the scale factor calculate the ratio of the corresponding sides of the image to the original, that is

scale factor = \frac{Z'Y'}{ZY} = \frac{9}{12} = \frac{3}{4}

Find the value of the expression (4x – 12) + (xy – 5) when x=6 and y = 2
Licemer1 [7]

Answer:

19

Step-by-step explanation:

Let us solve the parenthesis first according to PEDMAS (Parenthesis, Exponent, which ever comes first from left to right Multiplication and Division, which every comes first from left to right Addition and Subtraction.)

x=6, y=2

4x-12

Substitute using the given values

4*6 - 12 = 24 - 12 = 12

xy - 5

Substitute using the given values

6*2 - 5 = 12 - 5 = 7

Add up the two answers because we need to find the value of (4x - 12) + (xy - 5)

12 + 7 = 19

The answer is 19

Hope this helps :)

Have a nice day!
