Is 2x 3y linear equation?
Therefore .as a result the supplied linear equation problem's solution is shown to be a linear equation with two variables.
Define a linear equation.Any model that meets the algebraic equation y=mx+b is said to be linear. B is the slope, and m is the y-intercept. Since both y and x are distinct factors, the preceding sentence is commonly referred as a "mathematical model with two variables." Two-variable linear equations are referred to as bivariate equations. There are several applications for linear equations, all of which end in zero. If an equation has the form y=mx+b, where m stands for the slope and b for the y-intercept, it is classified as linear. The equation is written as Y=mx+b, where m denotes the slope and b
Here,
Assumed: 2x + 3Y = 0.
As a result, the following equation can be used to determine whether it is linear in two variables.
As x is the sole variable, as can be seen.
Therefore, it is a two-variable linear equation.
As a result, the supplied linear equation problem's solution is shown to be a linear equation with two variables.

Answer:
AB ≈ 9.11
Step-by-step explanation:
Using the tangent ratio in the right triangle
tan44° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{AC}{AB}[/tex] = [tex]\frac{8.8}{AB}[/tex] ( multiply both sides by AB )
AB × tan44° = 8.8 ( divide both sides by tan44° )
AB = [tex]\frac{8.8}{tan44}[/tex] ≈ 9.11 ( to 3 sf )

What is solution of the system?
A set of values for a variable that simultaneously satisfy each equation is the solution to a system of equations. A system of equations must be solved by identifying all possible sets of variable values that make up the system's solutions.
Given:
3(- n + 4) + 5n = 2n ← distribute and simplify left side
- 3n + 12 + 5n = 2n
2n + 12 = 2n ( subtract 12 from both sides )
2n = 2n - 12 ( subtract 2n from both sides )
0 = - 12 ← not possible
This indicates the equation has no solution

− [infinity] [infinity] is not a valid mathematical expression so it has no defined meaning.
The expression − [infinity] [infinity] is not a valid mathematical expression, and thus it has no defined meaning. It is not a valid mathematical expression because it contains two symbols, infinity and negative infinity, which do not interact with each other in any meaningful way. Infinity is a concept that is used to represent an unbounded or infinitely large value, while negative infinity is a concept used to represent a value that is infinitely small. When combined, these two symbols do not represent any meaningful mathematical quantity. Therefore, the expression − [infinity] [infinity] has no defined meaning.

A quantity with an initial value of 7800 decays continuously at a rate of 0. 1%

hundredth?
The question is asking for the value of a quantity that decays continuously at a rate of 0.1% per hour. We are given that the initial value of the quantity is 7800 and are asked to find the value after 1.25 days (30 hours).
What is a ratio in mathematics?
A ratio in mathematics demonstrates how many times one number is present in another. For instance, if a dish of fruit contains eight oranges and six lemons, the ratio of oranges to lemons is eight to six (that is, 8:6, which is equivalent to the ratio 4:3).
We can use the following formula to find the final value of the quantity after a certain amount of time:
final value = initial value * (1 - decay rate)^time
Where decay rate is given as a decimal (0.1% = 0.001)
Plugging in the given values, we get:
final value = 7800 * (1 - 0.001)^30
The final value is around 7396.65
Rounding the final value to the nearest hundredth, the final value after 1.25 days is:
7396.65 ≈ 7396.66
The value of the quantity after 1.25 days, to the nearest hundredth is 7396.66.

Angie is working on solving the exponential equation 23x = 6; however, she is not quite sure where to start. Using complete sentences, describe to Angie how to solve this equation.
Hint: Use the change of base formula: log base b of y equals log y over log b.
Step-by-step explanation:
I'm assuming that its 23 to the power x since you said it is an exponential equation.
as for the hint there is no specific base specified so I'll do the best I can with the answer.
Angie can begin solving by applying log to the base 23 on both sides. when this is done, Angie will be left with:
[tex] log_{23}( {23}^{x} ) = log_{23}(6) [/tex]
and as we know the power rule in logarithms allows us to remove the power within the expression.
hence, we'll get:
[tex]x log_{23}(23) = log_{23}(6) [/tex]
furthermore, if we have the same number and base within a logarithmic expression it will simply become 1 giving us the final answer:
[tex]x = log_{23}(6) [/tex]

What is the x-intercept of the line 4x y =- 4?
The x-intercept of the line 4x-y =- 4 is (1,0).
At x-intercepts, y=0 and at
y-intercepts, x=0.
So, to find the,
x-intercept, set y=0
4x−0=4
4x=4
x=1.
The points at which the graph of a function or an equation crosses or "touches" the x-axis of the Cartesian Plane are referred to as the x-intercepts. This could be thought of as a point with a y-value of zero. Let y equal 0 and then solve for x to determine the equation's x-intercepts.
Because the line crosses the x-axis when y=0, the equation for x must be solved in order to determine the x-intercept. We can solve for the intercepts when an equation is not in the form y = mx + b by solving for the remaining variable and plugging in 0 as necessary. To locate the y-intercept: solve for y and set x to zero.

Answer:
y= - 5/2x - 2
Step-by-step explanation:
Y=2/5x + 2
Making it perpendicular, the slope will change to it's reciprocal and swap operations (+ becomes -). 2/5 will be -5/2. We already know the y-intercept which is -2, so simply put, the equation in slope-intercept form is y = -5/2x - 2
Answer:
y = -5/2x + 3Step-by-step explanation:
Given function:
y = 2/5x + 2Perpendicular lines have opposite reciprocal slopes.
The line that is perpendicular to the given will have a slope of -5/2.
Now use the point (2, -2) and point-slope form to find the equation:

(Put your response in decimal form.) Altitude
The altitude of the right circular cone is 13.5 inches.
What is volume?
Volume is a term used in mathematics to describe the volume of three-dimensional space occupied by an object or a closed surface. The measurement of volume is done in cubic units, like m3, cm3, in3, etc. Volume is also referred to as capacity on occasion.
Here, the volume of a right circular cone varies jointly as the altitude and the square of the radius of the base
So our equation for volume becomes
V = c*h*r^2
where 'h' is altitude and
'r' is radius of base and
'c' is constant
Putting the values of V, h, r, in the volume equation.
we get,
154 = c*12*3.5*3.5
c = 22/21
Now we have volume = 77 cu and radius of the base =7/3, so putting the values we get,
77 = 22/21*h*7/3*7/3
or, h = 13.5 inches
Hence, the altitude of the right circular cone is 13.5 inches.
