Identify the variables in this Algebraic Expression<br> X+ 4y - 9

Lesechka [4]

Answer:

The expression $x + 4y - 9$ has two variables x and y.

Step-by-step explanation:

<u>What is a variable?</u>

A variable is a letter, for instance $x$ or $y$ , that represents an unknown number.

Given the expression

$x + 4y - 9$

The given expression has three terms which are x, 4y, and -9.

Here:

The term 'x' is the unknown variable x.

The term '4y' has a coefficient (the number next to a variable y) of 4.

The term '-6' is a constant.

As we already know that a variable is a letter, for instance x or y, that represents an unknown number. In other words, the values of x, or y are unknown to us.

Thus, the expression $x + 4y - 9$ has two variables x and y.

Can someone help answer this?

katrin [286]

9√2 is squared first.

so its 162.

now according to Pythagoras theorem,

x2+x2=162

2x^2= 162

x^2= 162÷2

x^2= 81

x= √81

x=9

AB¯¯¯¯¯¯¯¯ is the diameter of circle T. Point A is located at (-9,-1) and point B is located at (-1,-5). What are the coordinate

Makovka662 [10]

Answer:

The coordinates of the center of this circle are (-5 , -3)

Step-by-step explanation:

* Lets explain how to solve the problem

- The mid-point of the segment whose endpoints are (x1 , y1) , (x2 , y2)

is $(\frac{x_{1}+x_{2}}{2},\frac{y_{1}+y_{2}}{2})$

- AB is the diameter of circle T

∵ The diameter must passing through the center of the circle

∵ The center of the circle is the mid-point of all diameters of the circle

∵ The center of the circle is point T

∴ T is the mid point of the diameter AB

- Lets calculate the coordinates of point T by using the rule above

∵ A = (-9 , -1) and B = (-1 , -5)

∵ T is the mid-point of AB

- Let A = (x1 , y1) , B = (x2 , y2) and T = (x , y)

∴ x1 = -9 , x2 = -1 and y1 = -1 , y2 = -5

∴ $x=\frac{-9+-1}{2}=\frac{-10}{2}=-5$

∴ $y=\frac{-1+-5}{2}=\frac{-6}{2}=-3$

∴ The coordinates of point T are (-5 , -3)

* The coordinates of the center of this circle are (-5 , -3)

Multiply by this number to make the coefficient of the variable 1

Black_prince [1.1K]

Multiply by 9/25 to make the coefficient of the variable 1 the answer is 9/25.

<h3>What is a linear equation?</h3>

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

The question is incomplete.

The complete question is in the picture, please refer to the attached picture.

We have a given linear equation.

After solving the linear equation we get:

$\rm \dfrac{25}{9}x = 25$

To make the coefficient of the variable 1

Multiply by 9/25 on both sides.

$\rm \dfrac{9}{25}\times\dfrac{25}{9}x = 25\times \dfrac{9}{25}$

x = 9

Thus, multiply by 9/25 to make the coefficient of the variable 1 the answer is 9/25.
