A. x∧2+(x+20∧2=150∧2 is correct.
because you need to plug the numbers into the pathagoreum theorum which is
a∧2+b∧2=c∧2
150 is our c because it is the side right accross from the right angle.
which number is a and which number is b does not matter.
x is the distance north so we can assign that to a and the distace east is north plus 20 so we can assign b to x+20.
Means, for every 1 input, there is 1 coresponding output
normally x is input and y is output in form (x,y)
so just look for the option(s) that has/have every first number repeat with only 1 2nd number
A. -7 repeats with 5 and -3, not a function
B. no repeats of first number (6,-8) and (-5,-8) are fine because first numbers don't repeat, das is funciton
C. no repeats, function
D. no repeats, function
answer is B,C,D
Answer:
-49
Step-by-step explanation:
rule of thumb: whenever you have two negatives, they equal a positive! when you have one negative and one positive, it is a negative!
- let's start by going from left to right :))
- -24 -(-6) + (-31)
- -(-6) is actually + 6!
- -24 + 6 + (-31)
- +(-31) would be -31 because one - and one + is a -
- -24 + 6 - 31
- -18 - 31
- -49
