The rental fee for a Quad to ride off road and on the beach is $80, plus $10.00 for each hour that you ride. Write an algebraic expression for the total cost of renting the Quad for h hours?
Expression: ____________
Use the expression to determine the cost of renting the Quad for three and a half hours.
Total Cost is $__________
Algebraic expression for the total cost of renting the Quad for h hours is $80 + $10h. Cost of renting the Quad for three and a half hours is $115.
Short note on algebraic expressions?A mathematical sentence that incorporates coefficients, unknowable variables, algebraic operations, and constants is called an algebraic expression. The equals symbol, however, is not allowed in an expression. A mathematical phrase known as an algebraic expression combines variables and constants using the operational (+, -, & &) symbols. The equal (=) symbol is absent from algebraic symbols. Algebraic expressions include, for example, 10x + 63 and 5x - 3.
The rental fee for a Quad is $80 and it costs an additional $10.00 for each hour that you ride. So the total cost of renting the Quad for h hours can be represented by the algebraic expression:
$80 + $10h
where h is the number of hours you rent.
To find the cost of renting the Quad for three and a half hours, we can substitute h = 3.5 into the expression:
$80 + $10(3.5) = $80 + $35 = $115
So the total cost of renting the Quad for three and a half hours is $115.

Is inverse function concave?.
The concept is the Concave function. The answer is yes if the inverse function is convex in nature.
In mathematics, a concave function is the opposite of a convex function. A concave feature is also referred to as downward concave, downward concave, upward convex, vertex convex, or top convex.
The slope of the inverse decreases as the slope of f increases. Thus the inverse of a convex differentiable function with a non-zero derivative is strictly concave.
In general, it can be shown that the inverse of a convex function is concave. Geometrically, a function is concave if its graph lies across its tangents. A function is concave if its graph lies below its tangent.

How do you solve a 3 variable system of equations?.
When solving systems of equation with three variables we use the elimination method or the substitution method to make a system of two equations in two variables.
There are several methods to solve a system of equations with three variables, including substitution, elimination, and graphing. One common method is to use elimination, also known as the addition/subtraction method. This involves adding or subtracting equations in order to eliminate one of the variables and creating an equation with only two variables. Once you have a system of two equations with two variables, you can solve for one of the variables, substitute that value back into one of the original equations, and then solve for the remaining variable. After that you can use the value of the variables to find the values of the other variables.
Hence, When solving systems of equation with three variables we use the elimination method or the substitution method to make a system of two equations in two variables.

ABC has vertices A(0, 0), B(0, 4), and C(3, 0). Write the equation for the line containing the
altitude AR in standard form.
y= -4/3 x
4y-3x = 0
3y-4x=0
3x-4y=0
The equation for the altitude AR of triangle ABC will be 4y-3x=0 i.e. B.
What is a triangle?
Triangles are polygons in geometry that have three sides and three vertices. This figure is two-dimensional and has three straight sides. A triangle is a three-sided polygon. A triangle's three angles added together equals 180°. A single plane contains the triangle. The triangle is classified into six forms based on its sides and angles.
A triangle is categorized into three categories based on its sides, namely:
Scalene Triangle - Each side has a distinct length.
Isosceles Triangle - A triangle with two sides of equal length and one side of a different length.
Equilateral Triangle - A triangle has three sides that are of the same length.
A triangle is categorized into three categories based on its angles, namely:
Acute Angle Triangle - A triangle with all of its angles smaller than 90°.
Obtuse Angle Triangle - A triangle with one of its angles larger than 90°.
Triangle with a Right Angle - A triangle with one of its angles equal to 90°.
Now,
The general form of the linear line is:
y = mx + c where m is the slope and c is the y-intercept
Step 1: getting the slope:
Since AR is the altitude of ABC, therefore, AR is perpendicular on BC which means that slope of AR = -1/slope of BC
Therefore, we will need to get slope of BC:
We have point B = (0,4) and point C = (3,0)
slope of BC = (y2-y1) / (x2-x1) = (0-4) / (3-0) = -4/3
This means that:
slope of AR = m = 3/4
Step 2: getting the y-intercept:
Since point A belongs to the altitude, therefore, point A satisfies the equation of the line. So, to get the y-intercept, we will use point A to substitute in the equation of the line and solve for c as follows:
y = mx + c
y = (3/4) x + c
0 = (3/4)(0) + c
c = 0
Hence,
y = (3/4) x

What is limit in maths class 11?.
The limit is normally defined as

It is read as “the limit of f of x, as x approaches c equals L”.
In mathematics, limits are the points at which a function approaches the output for the specified input values. Calculus and mathematical analysis depend heavily on limits, which are required to determine integrals, derivatives, and continuity. It is applied during the analysis process and always focuses on the function's behaviour at a certain time. The idea of the limit of a topological net broadens the definition of the limit of a sequence and relates it to the limit and direct limit in the theory category. In general, there are two sorts of integrals: definite integrals and indefinite integrals. The upper limit and lower limit for definite integrals are correctly defined.
Limits in maths are unique real numbers. Let us consider a real-valued function “f” and the real number “c”, the limit is normally defined as
[tex]lim _{x- > c} f(x) = L[/tex]
It is read as “the limit of f of x, as x approaches c equals L”. The “lim” shows the limit, and fact that function f(x) approaches the limit L as x approaches c is described by the right arrow.
A function may get close to two distinct limits. There are two scenarios: one in which the variable approaches its limit by values larger than the limit, and the other by values smaller than the limit. The right and left-hand limits still exist even though the limit is not specified in this situation.

The easiest way to determine equivalent expressions for algebraic expression is by using the factoring.
Equivalent expression : In Algebra, equivalent expressions are algebraic expressions that, although they look different, turn out to really be the same. And since they are the same, they will produce the same results when same value substitute for their variables. For example, 3(x + 2) and 3x + 6 are equivalent expressions because the value of both expressions remains the same for any value of x. When writing equivalent expressions, we must be sure that each side of the equal number corresponds to the same number. Using the factoring :
Identify the common factors in the parts of the equation.It may be necessary to divide the equation to find an equivalent expression.If the expression is, 2xy + 4x, In this case, both numbers are divisible by 2.Take out the first common number :2(xy + 2x). As y see that there is

What is Similarity of Triangles ?If two items have the same shape or have the same shape as their mirror images, they are said to be Similar. One can be produced from the other more accurately by evenly scaling it, perhaps with the addition of further translation, rotation, and reflection.
If the sides are in the same ratio or proportion and the angles are equal (corresponding angles), two triangles will be comparable (corresponding sides). Similar triangles may have varying individual side lengths, but they must have equal angles and the same scale factor or matching ratio of the side lengths. If two triangles resemble one another, then
Triangles with similar angle pairings have all the same angles.Triangles have proportionate sides on all matching sides.In ΔTPQ and ΔTPS
∠T is common in both triangle

What are the zeros of the polynomial function f x x3 − 2x2 − 24x?.
The zeros of polynomial function f(x) = x³ - 2x² - 24x are x = 0, x = -4 and x = 6
Consider given function f(x) = x³ - 2x² - 24x
We know that the zeros of a function are nothing but the values of the variable of the function that makes the function value equal to 0.
To find the zeros of function f(x), we need to equate f(x) to zero then solve it for x.
⇒ f(x) = 0
⇒ x³ - 2x² - 24x = 0
⇒ x (x² - 2x - 24) = 0
⇒ x = 0 OR x² - 2x - 24 = 0
Now we solve quadratic equation x² - 2x - 24 = 0
x² - 2x - 24 = 0
x² - 6x + 4x - 24 = 0
(x - 6)(x + 4) = 0
x = 6 OR x = -4

What is the answer to this problem I need help please and thank you .9-z+3-2z=
Answer:
12 - 3z or 3 .9 - 3z
Step-by-step explanation:
1 - if it is just a "9" and not a "0 .9" the answer is "12-3z". You will have to isolate the expressions with the "z" (the 2z and the z). They have a "-" before them, so they are negative expressions (-2z and -z). When the letter is alone, we supose that is a whole, not a decimal, expression, so it is like "1z". After all, you will have two negative expressions, the "-1z" and the "-2z", then you will just add "-1z" and "-2x" (-1z + (-2z) = -1z -2z = -3z
Now, you will need to add "9" and "+3" (9 + (+3) = 9 + 3 = 12).
Now, you have a "-3z" and the "12", and you will add they (-3z + 12 = 12 + (-3z) = 12 - 3z).
2 - But, if it is a "0 .9" ( "0 .9" is the same of " .9" and not a "9" the answer is "3 .9 - 3z". Now it is the same as the number 1 (just do the same from the "You will have" to the "-1z -2z = -3z".
Now, you need to add "0 .9" and "+3" ( .9 + (+3) = .9 + 3 = 3 .9).
So, you have the "-3z" and the "3 .9", and you need to add them ( 3 .9 + (-3z) = 3 .9 - 3z ).

How do you find the inverse of a linear graph?.
The inverse of the linear graph can be found by interchanging the values of x and y
When a function is stated in the form y = mx + b, where m and b are real integers and m is not equal to 0, the function is said to be linear. A linear graph is the graph of a linear function. The inverse of a linear graph can be found in two steps -
The first step is to replace the value of y with x and x with y in the original equation of the linear function.The second step is to solve the equation for x in terms of y, which will give the inverse function.For example, if the linear function equation is y = 3x + s, the inverse function can be found by swapping x and y, and solving the equation for x: y = 3x + 2 and x = 3y + 2. Alternatively, the inverse function can also be determined by interchanging x and y values and changing the sign of the slope of the original function. Therefore, the inverse function of y = 3x + 2 is x = (2/3)y - 2/3
