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.

I'm not sure what they mean by "relations that represents a function". I don't understand this.
sergeinik [125]
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

-24-(-6)+(-31)<br> step by step<br> be sure to simplify first
trasher [3.6K]

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!

  1. let's start by going from left to right :))
  2. -24 -(-6) + (-31)
  3. -(-6) is actually + 6!
  4. -24 + 6 + (-31)
  5. +(-31) would be -31 because one - and one + is a -
  6. -24 + 6 - 31
  7. -18 - 31
  8. -49

State the domain and range of the following function:
mojhsa [17]

Answer:

Domain = \{-3,0,2,1,6,3\}

Range = \{4,6,-2,-3,-7,2\}

Step-by-step explanation:

Given

\{(- 3,4), (0,6), (2, - 2), (1, - 3), (6, - 7), (3, 2)\}

Required

The domain and range

A function is represented as:

Function = \{(x_1,y_1),(x_2,y_2),....(x_n,y_n)\}

Where

x \to domain

y \to range

So, we have:

Domain = \{-3,0,2,1,6,3\}

Range = \{4,6,-2,-3,-7,2\}
