Substitute the values of x and y into the expression -3x2 + 2y2 + 5xy - 2y + 5x2 - 3y2. Match that value to one of the numbers. 1. x = 0.5, y = 1.665 2. x = -1, y = -3 -1 3. x = , y = 14 4. x = 0, y = 2.5 9.17 5. x = √2, y = √2 0.44 6. x = 2, y = -1 -11.25

a line is an defined derm because it

a)contains an infinite number of points b) can be used to create other geometric shapes c)describes something that does not have width or depth d) is a term that does not have a formal definition. a line is an undefined term because it: contains an infinite number of points.

0.6, 3/5, and 6% are the 3 same portion.

but, when they're all changed to a decimal they would equal to 0.6.

hope this , good luck!

step-by-step explanation:

from this example, we can see that subtracting with integers is the same as adding the opposite. we can solve using a number line or by using the saying "keep, change, change" to us solve. it is important to remember that we can subtract a negative and end up with a larger number than we started with.
