How can I evaluate this when x=1/2 and y= -5

Plug in the x and y values

4(1/2)^2 -3(-5)

Apply the exponent so (1/2)^2 or 1/2 • 1/2 which is equal to 1/4

Now you have 4(1/4) -3(-5)

Multiply them out:

4(1/4)=1

-3(-5)=15 [remember a negative times a negative equals a positive]

So now your equation is 1-15

your answer is 1-15= -14

Step-by-step explanation:

answer: 16

step-by-step explanation: first you would add 6+6 which equals 12 then add 2+2 which equals 4. then add 12 + 4 which is 16.

hope this ^_^

step-by-step explanation:

well if you round, things become much more simple. round 5.95 to 6, 4.25 to 4, and 1.05 to 1. now, add 6+4+1 and that would equal 11. so the items together would equal to about $11.
