Answer:

First relation: It's a function. No order pair need to be changed.

Second relation: It's a function. No order pair need to be changed.

Third relation: It's not a function. The ordered pair (5,8) needs to be changed.

Step-by-step explanation:

A function may not have two y-values assigned to the same x-value.

Each x-element of the first relation has only one y-element associated with it. So we conclude that it's a function.

Each x-element of the second relation has only one y-element associated with it. So we conclude that it's a function.

The points (5,8) and (5,2) shows that there are two y-elements (y=8 and y=2) associated with the value x=5. So we conclude that it's not a function.

(3x²+3x+5)+(7x²-9x=8)=10x²-12x=13
Brilliant_brown [7]

The value of x is equal to -5/6

To solve this question, we have to add two polynomials together. The polynomials are;

  • 3x^2+3x+5
  • 7x^2-9x=8
<h3>Addition of Polynomials</h3>

This involves adding of two or more different polynomials together. The polynomials adding together are or must be of the same degree. i.e x^2 must add to another coefficient of x^2 and x^3 adds to another coefficient of x^3 and so on.

In this given question, let's add the polynomials together.

(3x^2+3x+5) + (7x^2-9x = 8\)\\3x^2 + 7x^2 + 3x-9x+5-8 =10x^2-6x-3

Now, let's equate this with the last polynomial given

10x^2-6x-3=10x^2-12x-13\\10x^2-10x^2-6x+12x-3+13\\0+12x+10\\12x=-10

Let's solve for x

12x=-10\\x=-\frac{10}{12}\\x = -\frac{5}{6}

The value of x is equal to -5/6

The weight of an object on the moon is 1/6 of its weight on earth. If a moon rock weighs 20 1/2 lb on earth, how much did the ro
Pie

Step-by-step explanation:

20 1/2 = (20×2 + 1)/2 = 41/2.

to create 1/6 of that we have to multiply it by 1/6 :

41/2 × 1/6 = 41/12 = 3 5/12

the rock weighed 3 5/12 lb.
