2(3) - (-2) = 8 … r u missing part of the question?
It's A. y=5 because y-lines are horizontal, and x-lines are vet=rtical, and all horizontal and vertical lines are perpendicular (they create a right angle). y=5 line crosses all points that are (x,5) because the 5 in (x,5) is 5 up from the origin and x left or right. y=5 is a horizontal line that is 5 up from the origin.
Answer:
-3.1
Step-by-step explanation:
5.1 + 4.2 = 9.3
9.3/-3 = -3.1
To round a number to the nearest tenth, look at the next place value to the right (the hundredths). If it's 4 or less, just remove all the digits to the right. If it's 5 or greater, add 1 to the digit in the tenths place, and then remove all the digits to the right.
