Answer:

1st one: -3,-4 away

2nd one: Lets just say I got kinda confused on that one so sorry for any inconvenience on my behalf from this question.

Step-by-step explanation:

I will call (-3,-4) Point A and I'll call (0,0) Point B. Point A is at (-3,-4) and Point B is obviously at the origin. That makes it easy, because you just subtract Point A by Point B to find how far away they are.

<h2>Linear system</h2>

It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.

Given

A group of friends bought 5 containers of popcorn and 4 granola bars at the movie theatre for $42.50.

The next week, the same group of friends bought 3 containers of popcorn and 6 granola bars for $34.50.

<h3>To find </h3>

The equation and solution of the equation.

<h3>How to get it?</h3>

Let p represent the cost of one container of popcorn.

Let g represent the cost of one granola bar.

A group of friends bought 5 containers of popcorn and 4 granola bars at the movie theatre for $42.50.

5p + 4g = 42.50 .....1

The next week, the same group of friends bought 3 containers of popcorn and 6 granola bars for $34.50.

3p + 6g = 34.50 .....2

From Equations 1 and 2, we have

p = 6.5  and  g = 2.5

Thus, the cost of one container of popcorn and granola is $6.5 and $2.5.

Two fractions have denominators of x^2+ 6x + 9 and x^2. What is the Least Common Denominator?
Gala2k [10]

SOLUTION

Write out the denominator of the fraction, we have

\begin{gathered} x^2+6x+9 \\ \text{And } \\ x^2-9 \end{gathered}

We want to obtain the least common denominator.

To do this, we need to factorize each of the expression given

\begin{gathered} x^2+6x+9 \\ =x^2+3x+3x+9 \\ =x(x+3)+3(x+3) \\ =(x+3)(x+3) \end{gathered}

Then we factorise the other fraction using difference of two square

\begin{gathered} a^2-b^2=(a-b)(a+) \\ \text{Then} \\ x^2-9=x^2-3^2 \\ =(x-3)(x+3) \end{gathered}

The the factorise expression becomes

(x+3)(x+3)\text{ and (x-3)(x+3)}

To obtain the least common denominator, we select the common factor and the product of the other factor,

Hence

\begin{gathered} \text{common factor=(x+3)} \\ \text{The other factors are (x-3)(x+3)} \\ \text{Then } \\ \text{Least co}mmon\text{ denominator becomes } \\ (x+3)(x-3)(x+3) \end{gathered}

Thus

The Least Common Denominator is (x +3)(x+3)(x-3) (Last Option )
