Question

Evaluate and match each expression on the left to its value on the right, when x=8 and y=3.

Answer 1

12-y------------> 9

3x-y------------>21

4y-10----------->2

1/4 xy-----------> 6

Solution,

Given,

X=8

y=3

Now,

`1. \: \: 12 - y \\ \: \: \: = 12 - 3 \\ \: \: = 9 \\ 2. \: \: 3x - y \\ \: \: = 3 * 8 - 3 \\ \: \: = 21 \\ 3. \: \: 4y - 10 \\ \: \: = 4 * 3 - 10 \\ \: = 12 - 10 \\ \: \: = 2 \\ 4. \: \: (1)/(4) xy \\ \: \: = (1)/(4) * 8 * 3 \\ = 6`

hope this helps...

Good luck on your assignment...
