Answers

Answer 1

Answer:

Algebra is the branch of Maths that uses alphabetical letters to find unknown numbers. These letters are also called variables. ... Algebra involves the simple operation of mathematics like addition, subtraction, multiplication, and division involving both constant as well as variables. For example, x+10 = 0.

Step-by-step explanation:

In its most general form, algebra is the study of mathematical symbols and the rules for manipulating these symbols; it is a unifying thread of almost all of mathematics. It includes everything from elementary equation solving to the study of abstractions such as groups, rings, and fields.

Answer 2

Hiiii!

Here's what algebra is:

Algebra is a branch of mathematics dealing with symbols and the rules for manipulating those symbols. In elementary algebra, those symbols (today written as Latin and Greek letters) represent quantities without fixed values, known as variables. ... The letters x and y represent the areas of the fields.

In simple words: a generalization of arithmetic in which letters representing numbers are combined according to the rules of arithmetic.

Hope it helps! ( ꈍᴗꈍ)

|9+40i| = |√9^2 + -40^2| = √1681 = 41

Answer: 41

Answer:

41

Step-by-step explanation:

We know that complex numbers are a combination of real and imaginary numbers

Real part is x and imaginary part y is multiplied by i, square root of -1

Modulus of x+iy =

Here instead of x and y are given 9 and 40

i.e. 9+40i

Hence to find modulus we square the coefficients add them and then find square root

|9+49i| =

By long division method we find that

|9+40i| =41

Answers

An equation is an expression that shows the relationship between two or more variables and numbers.

Let x represent the money that Maribel would save on the sale.

Since she would save 20% on purchases, hence money saved on purchase of $35 is:

x = 20% of $35 = 0.2 * 35 = $7

What is the recursive rule for the sequence shown in the graph

Answers

Answer:

[tex]a_{n} =a_{n-1} -4[/tex]

explanation:

The recursive rule for the given graph will be [tex]a_{n} = a_{n-1}-4[/tex] thus, option (A) is correct.

What is a graph?

A graph is a diametrical representation of any function between the dependent and independent variables.

For example y = x² form a parabola now by looking at only the graph we can predict that it has only a positive value irrespective of the interval of x.

In the given graph, as n increases [tex]a_{n}[/tex] decreases.

At n = 4 , a₄ = a₃ - 4 = 5 - 4 = 1

Thus, [tex]a_{n} = a_{n-1}-4[/tex]  will be the recursive rule.

Hence "The recursive rule for the given graph will be [tex]a_{n} = a_{n-1}-4[/tex]".
