Therefore , the solution of the given problem of algebra comes out to be the value of expression is 17.

Algebra is one of the numerous variables of mathematics. Algebra is, broadly defined, the study of numeric and the rules for employing them in formulae. It is a common theme that goes through practically all of mathematics. Algebra is the branch of mathematics that provides the most assistance in describing circumstances or issues through the use of formulas. In algebra, we use integers, such like 2, 7, 0.068, etc., which have a defined or definite value. Algebra slight changes like x, y, & z in addition to utilizing integers.

Here,

Given :

a= -2

b= 3

c = -3

so,

=> -a- 2bc - |c|

=> 2 -2*3*-3 - |-3|

=> 2 + 18 -3

Quadratic equations are the polynomial equations of degree 2 in one variable of type f(x) = ax^2 + bx + c = 0 where a, b, c, ∈ R and a ≠ 0. It is the general form of a quadratic equation where 'a' is called the leading coefficient and 'c' is called the absolute term of f (x).

All of given options contain quadratic functions. One way to determine the extreme value is squaring the expression with variable x.

Option B contain the expression where you can see perfect square. Thus, equation  y =-3(x-2)^2+5  (choice B) reveals its extreme value without needing to be altered.

To determine the extreme value of this equation, you should substitute x=2 (then x value that makes expression in brackets becomes equal to zero) into the function notation:

y =-3(x-2)^2+5

substitute x = 2,

y =-3(2-2)^2+5

The slope(m) of the line that passes through the points (1, −3) and (3, −5) is m = -1.

The slope of a line determines the inclination of the line with the positive x-axis.

The slope of the line passing through (x1, y1) and (x2, y2) is given by m =(y2 - y1) / (x2 - x1)

Given that,

Here, (x1, y1) = (1, −3) and (x2, y2) = (3, −5)

m = (y2 - y1) / (x2 - x1)

m = [-5 - (-3)] / [3 - 1]

m = [-5 + 3] / [2]

m = [-2] / 2

m = -1

A tangent is a line that touches a curve at a single point, but does not intersect the curve at that point.

The slope of a tangent line at a point on a curve is equal to the derivative of the curve at that point. Therefore, finding the tangent line to a curve at a particular point is equivalent to finding the derivative of the curve at that point.

For example, consider the curve y = x^2. If we want to find the tangent line to this curve at the point (2,4), we can take the derivative of y = x^2, which is y' = 2x. Setting x equal to 2, we find that the slope of the tangent line at (2,4) is 4. We can then use this slope to find the equation of the tangent line: y - 4 = 4(x - 2), which simplifies to y = 4x - 4.

Therefore the answer is $72.

Let the tenth and once place value digits of the actual value of bill be x and y. Then actual value of bill in dollars is expressed by

10x + y

The value of bill obtained by interchanging the two digits in dollars is

10y + x

It is said that by interchanging digits the shopkeeper undercharged him by $45.0, that is

(10x + y) - (10y + x) = 45

9x - 9y = 45

A drop of water is denser than a ping-pong ball.

Usually, water is made of particles that are firmly pressed together. In differentiation, plastic (the material ping pong balls are made of) may be a lightweight fabric and the particles are not as firmly stuffed together.

The thickness of a ping pong ball is 0.0840 g/cm³, though water’s thickness is 997 kg/m³. Subsequently, ping pong balls aren’t about as thick as water and will continuously coast and surface greatly quickly.

The ping pong ball appears to oppose gravity and coast within the air.

Ping-pong balls drift within the water since they are amazingly lightweight, empty, and filled with air. Too, the water’s surface pressure makes it simple for the ping pong ball to drift.

In expansion, water is denser than ping pong balls, making them look for the most noteworthy point of water.

3y + 2x = 44 is the equation of the line through (10, 8) and (4, 12).

A linear equation has the slope-intercept form y = mx + b. Variables in the equation are x and y. When x is 0, the integers m and b provide the line's slope (m) and the value of y. Because (0,y) is the location where the line crosses the y-axis, the value of y when x is 0 is referred to as the y-intercept.

Given, two coordinates of a line [tex]\left(10,8\right) and \left(4,12\right)[/tex]

The slope of the line formula is:

[tex]m = \frac{y₂ - y₁}{ x₂ - x₁}[/tex]

Let's substitute our numbers.

[tex]m = -\frac{8 -12}{4-10}[/tex]  =  -4/6

The GCF of these two numbers is 2

So, our slope  =  -2/3

The general equation of a line is y = mx +c

Therefore the equation of the line is y = -2/3x + c

Since, this line passes through ( 10, 8 )

Hence, it must satisfy these coordinates

8 = -2/3 * 10 + c

44/3 = c

Thus the equation of the line is y = -2/3x +44/3

Step-by-step explanation:

The cost of taking x dance lessons is 50 + 20x dollars. This should be less than or equal to the amount of money Alexis has, which is 150 dollars. We can represent this relationship with the following inequality:

50 + 20x ≤ 150

This inequality can be simplified to the following:

20x ≤ 100

Dividing both sides of the inequality by 20 gives us the following:

x ≤ 5

Therefore, Alexis can take up to 5 dance lessons within her budget.

We can rewrite m^91 + 2m^90 as (m+2m^90)^2 - m^90.

We are looking for values of m such that m+2m^90 is an integer.

For m = 30, m+2m^90 = 30 + 230^90 = 30 + 2(30^90) = 60, which is an integer.

For m = 24, m+2m^90 = 24 + 224^90 = 24 + 2(24^90) = 48, which is also an integer.

For the other values of m, m+2m^90 is not an integer. Therefore, the only values of m for which m^91 + 2m^90 is the square of an integer are m = 24 and m = 30.

The graph would be a straight line with a slope of 4, passing through the origin.

The equation f(x) = 4x can be expressed in slope-intercept form as y = 4x + 0, where the slope is 4 and the y-intercept is 0. This means that the graph of f(x) = 4x is a straight line with a slope of 4 that passes through the origin (0, 0).

The graph of f(x) = 4x is a line with a positive slope that passes through the origin and extends infinitely in both the positive and negative directions. The y-intercept is 0 and the x-intercept can be found by setting y = 0 and solving for x, which gives x = 0. For any given x-value, the corresponding y-value can be found by substituting the x-value into the equation f(x) = 4x and solving for y.

The equation that represents the situation could be 3/4(18 + s) = 31.50 and the solution is s = 24 thus option (D) is correct.

There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.

In another word, the equation must be constrained with some constraints.

Part (A)

Given that;

Cost of skirt = s

cost of blouse = $18

She bought it at 3/4 of that cost,

The Total pay = 3/4 of the total cost

3/4(18 + s) = 31.50

Part (B)

By the distributive property of multiplication then we get;

3/4(18) + 3/4(s) = 31.50

3/4(s) = 31.50 - 13.5

3/4(s) = 18

s = 18 x  4/3 = 24
