Answer:
they are related by ________
Step-by-step explanation:
Answer:
x = 113
Step-by-step explanation:
( 5x + 685 ) + ( 12x - 106 ) = 2500 ( 685 - 106 = 579)
17x + 579 = 2500
17x = 2500 - 579
17x = 1921
x = 1921 / 17
x = 113
Answer:
A= 74.47

Step-by-step explanation:
1. First question, do they represent functions? The one o. the left is a function because if you do the vertical line test. It only passes through a point once so it is a function. while on the right if you do the vertical line test, it passes through a point twice so it not a function. For 2.. n other words, since the domain of this equation is all real numbers or negative infinity to positives infinity
let say x=1 and x=-1 and we use the equation

when we plug both those in we get

this means that we can have two different x-values to equal out to the same y value. This is the definition of a function. So the one on the right is a function.
However the one on the left is a relation. TO Prove it, the domain of that function is all real numbers equal to or greater than zero, so let use 4.


Since there are 2 possible answer choices as the y value, this isn't a function. It a relation. It maps a group of ordered sets to one x value. Which is the opposite of the function. So the one of the left is a relation
