v = 18

f(2) is -8

According to the question,

Given that,

f(x)=2x-3x^2

In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an ‘equal’ sign. The most basic and simple algebraic equations consist of one or more variables in math.

Example of an Equation:

4y + 2 = 18

4×2 + 3x − 28 = 0

9m = 49.5

Equation Types

Algebra considers two prominent families of equations, namely polynomial equations and linear equations. Polynomial equations with one variable can be written in P(x) = 0, where P is a polynomial, and ax + b = 0 is the general form of linear equations. Here, a and b are parameters. We can practice geometric or algorithmic methods from linear algebra or mathematical analysis to solve these equations. Also, there are different types of equations, such as:

Linear equations

Quadratic equations

Cubic equations

Quartic equations

Differential equations

Parametric equations

Equation of a line

The standard form of the equation of a line is A x + By + C = 0. The slope-intercept form of an equation is y = mx + b, where m is the slope of the line and b is the y-intercept. However, there are various types of equations to represent lines.

Equation of x-axis

Generally, we say that the equation of the x-axis equation is of the form y = 0. However, we can also write the x-axis equation as x = c where c is constant.

The x-axis comprises all the real values of x, although the value of y is equal to 0 on the complete x-axis.

Thus, x can be recognised as constant and y as 0.

In the coordinate system representation, we can represent any point on the x-axis as (c, 0), where c is any real number.

Therefore, the x-axis formula will be x= c + y

Here,

c = constant

y = 0

The x-axis formula is x = c, where c is constant.

Equation in One Variable

The equation in one variable means the equation containing only one variable. Let’s have a look at the below equations.

17 – 9 = 8

x + 4 = 4y + 22z

4x2 + 3x – 7 = 0

The three examples above represent equations that propose equality (could be true or not) between two expressions.

The first equation does not contain any variable.

The second equation has three different variables, such as x, y and z. Thus, it is a multivariate equation.

The third equation contains only one variable, i.e. x.

Step-by-step explanation:

it us a right triangle so we can use the equation

Answer:

b = a² - 6

Step-by-step explanation:

a = [tex]\sqrt{b+6}[/tex] ← square both sides to clear the radical

a² = b + 6 ( subtract 6 from both sides )

a² - 6 = b

The equation has just two solutions, which are 11 and 7.

While the inequality will have a range of solutions, which is:

7 ≤ w ≤11

That is the difference.

Here we have an inequality:

|w - 9| ≤ 2

And an equation:

|w - 9| = 2

To solve these we can start by solving the equation, it gives two equations:

w - 9 = 2

w - 9 = -2

With these we can get two solutions for w,:

w = 2 + 9 = 11

2 = -2 + 9 = 7

Then the equation has just two solutions, which are 11 and 7.

While the inequality will have a range of solutions, which is:

7 ≤ w ≤11

If PQR is similar to WXY and PQ=12 cm and WX=9 cm and the area of WXY is 72cm², then the area of PQR is equal to 128 cm².

The area of PQR can be determined by first finding the scale factor. The scale factor in mathematics can be defined as the ratio of the length of a side of one figure (which in this case is a triangle) to the length of the side of a similar figure.

Therefore, the scale factor = 9 / 12

Now by using theorem 61,

area ΔWXY / area ΔPQR = (9/12)²

As the area of WXY = 72cm², therefore;

72 / area ΔPQR = 81 / 144

81 (area ΔPQR) = 144 × 72

81 (area ΔPQR) = 10,368

area ΔPQR = 10,368 / 81

area ΔPQR = 128 cm²

Hence, the area of PQR is calculated to be 128 cm².

Answer:

length = 23 inches , width = 4 inches

Step-by-step explanation:

let width be w then length l = 2w + 15

the perimeter P is calculated as

P = 2l + 2w

given P = 54 , then

2(2w + 15) + 2w = 54

4w + 30 + 2w = 54

6w + 30 = 54 ( subtract 30 from both sides )

6w = 24 ( divide both sides by 6 )

w = 4

l = 2w + 15 = 2(4) + 15 = 8 + 15 = 23

the length is 23 inches and width is 4 inches

The product of ∛3 and 5√3 is 15√3⁸ (Option C).

This question can be easily solved by using the concept of roots. The two terms mentioned in the question are ∛3 ( cubic root of 3 ) and  5√3 (5th root of 3 ). This question can be solved in 4 easy steps

Step 1 : Identify the power of the root and take LCM of those numbers.

In this case, the powers of root for ∛3 and 5√3 are 3 and 5, respectively. Take LCM of 3 and 5.

LCM = 3 x 5 = 15

=> We get the LCM of 3 and 5 as 15.

Step 2 : Write the given numbers in the form of fractional powers

∛3 = 3¹ˡ³  => The power of 3 = 1/3

5√3 = 3¹ˡ⁵  => The power of 5 = 1/5

Step 3 : Multiply and divide the powers of the base number ( in this case 3 ) with a number such that you get the denominator as the LCM ( in this case 15 )

1/3  can be multiplied and divided by 5 to get the denominator as 15

=> 1 * 5 / 3 * 5 = 5 /15

1/5  can be multiplied and divided by 3 to get the denominator as 15

=> 1 * 3 / 5 * 3 = 3 /15

Step 4 : Find the product of the two terms

15√3⁵ x 15√3³ = 15√3³⁺⁵ = 15√3⁸

Therefore, using the concept of roots and fractions, we get the product of ∛3 and 5√3 as 15√3⁸.
