Answer by JKismyhusbandbae: This is not a function because the two in the domain area is paired with 21 and 25. A function is basically whenever there is no domain that repeats.
If you have a discount on an item..
ex. 15% off coupon for $20 shirt
20 x 0.15= $3 <--- 15% of 20
20-3=$17 <--- final price of shirt after coupon
find the area first then add 22 and 5
Let the actual size be x, then
(5 x 10^2)x = 1.2 x 10^2
x = (1.2 x 10^2 / 5 x 10^2) = 0.24 millimeters
Therefore, the actual size is 0.24 millimiters.
-110x+40
You need to use the distributive property for this problem
You multiply 22x times -5 (which is -110x) and -8 times -5 (which is 40) to get -110x+40
