Evaluate the expression when x=-2 and y=3.
-y+8x
0
Х
5
?

Step-by-step explanation:

First here is the problem

-y + 8x

nwo that u have the problem substitute the variables with numbers...see example

-3  +  (8) (-2)

Then Order of operations do the multiplication...so see example below

-3 + (16)   Its negative -16 because a positive and negative when multiplied is          negative

Now -3 + 16 = 13

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units
