Help with simple algebra

Today let me help you on simple algebra. :et me explain this to you with the help of following example

Find algebra word problems on solving equations.

Question: Which of the following equation have x=2, y=3 as solution ?
(a) 8x-y = 12 (b) 2x+3y = 10

Answer: (a) Substitute x=2, y=3 in 8x-y=12
8(2)-3=12
16-3=12

x=2, y=3 is not a solution of 8x-y=12
(b) Substitute x=2, y=3 in 2x+3y=10. This could also help us on horizontal line test
2(2)+3(3)=10
4+9=10

x=2, y=3 is not a solution of 2x+3y=10.

Composition of Functions

Introduction for composition and invertible function:

In this article let me help you on composition of functions. An invertible functions for ƒ is a function from B to A, with the property that a round trip (a composition) from A to B to A returns each element of the first set to itself. A functions ƒ that has an inverse is called invertible; the inverse function is then uniquely determined by ƒ and is denoted by ƒ⁻¹. Function composition is the applications of one function to the results of another. For instance, the functions f: X → Y and g: YZcomprised by computing the output of g when it has an argument of f(x) instead of x

Q. Composition of a function as : h(x)= x2+2x-3. determine dom of f, dom of gand dom of h. This could also help us on intermediate algebra help

Answer 1

Composition is the operation of taking the output from one function and using that as the input to a second function. this site!

How to find percentage of a number?

Today let me try to help you on how to find percentage of a number. Since we have studied all about percentage let me give you an example to help you on this better. Keep reading if you still have any doubts do leave your comments.

Here is an illustration to show how to find percentage of a number.

Example : Calculate 25% of 70

Solution :

Given Number has to be written as,

25  x 70
100

or it can be simplified as

 1  x 70
4

 70   This could also help us on transformations math
4

= 1.75

algebra calculator

Introduction of free online algebra calculators:

Algebra Calculator is the part of mathematics which always deals with the study of operations such as addition, subtraction, multiplication and division. Algebra includes variables, constants, polynomials, exponents, terms and expressions. Basic operation of algebra is to balance the expression on both sides. This article free online algebra calculator briefly tells you the operations of algebra with various examples.
Examples of Free Online Algebra Calculators:

For free online algebra calculators consider the following examples.

Ex 1: Simplify the expression:

10(a-5) + 7b-4(2a -3b+5) +15

Sol : = (10a-15) + 7b-4(2a -3b+5) +15.

= 10a-15 + 7b -8a+12b-20+15.

= 10a-8a+7b+12b-15-20+15. This could also help us on factors of 25

= 2a+19b-20.

fractional notation calculator

Fractions :

In This section let me help you on fractional notation calculator

A certain part of the whole is called as fractions. The fractions can be denoted as a/b , Where a, b are integers. We can multiply two or more fractions. There are three types of fractions in math,

1) Proper fractions

2) Improper fractions

3) Mixed fractions. This could help us on complex fractions calculator

Online math help

Introduction to Online Math Help Division:
In this article let me help you on online math help. Many online websites are available today. In those websites, the quotient can be obtained by dividing two numbers explained step by step briefly about the topic for lower grade students to understand clearly. Division is said to be dividing anything into parts. The operation that determines how many times a quantity contained in another called as inverse of multiplication. The result of division is called as quotient.

This could also help you on online algebra 1 help. In division a ÷ b is c. Here “a” is dividend and “b” is divisor and “c” is called as quotient. Let us see about online math help division in this article.

Calculus Problem Help

Introduction to calculus problem help:-

In this lesson lets study about calculus problems online. Before i teach you on calculus issue let me help you what is calculus and how does it importance to arithmetic.

What is calculus?
Calculus (Latin, calculus, a tiny stone used for counting) is a branch in arithmetic focused on limits, functions, derivatives, integrals, and boundless series. This subject constitutes a major part of modern arithmetic schooling.

Example issue on calculus:

Query: Differentiate the given equation with respect to t. y = - 2t3 + 8t2 + 46t.

Solution:
Given: y = - 2t3 + 8t2 + 46t.
Differentiate with respect to t,
dy = - (2 × 3)t(3 - 1) dt + (8 × 2)t(2 - 1) dt + 46t(1 - 1) dt.

= - 6t2 dt + 16t dt + 46 dt.

= (- 6t2 + 16t + 46) dt.

dy / dt = - 6t2 + 16t + 46. This could also help us on calculus problem solver

Answer:
d/dt(- 2t3 + 8t2 + 46t) = - 6t2 + 16t + 46.
