Answer:

b= -8

Step-by-step explanation:

Isolate the variable by dividing each side by factors that don't contain the variable. my answer is -8 but just multiply 5 by -8. and solve

-14+6b+7-2b=1+5b

-7+4b=1+5b

-1 -1

-8+4b=5b

-4b -4b

-8=b

Answer:

x - 10

Step-by-step explanation:

a number is used as a variable and "the difference" means subtraction

Answer:

x = -1

Step-by-step explanation:

distribute:

3x + 3 = -2 (x -1) -4

distribute:

3x + 3 = -2x + 2 - 4

calculate difference:

3x + 3 = -2x - 2

move variable to left and change sign

3x + 2x + 3 = -2

3x + 2x = 2 - 3

collect like terms

5x = -2 - 3

5x = -5

x = -1

Answer:

x = -1

Step-by-step explanation:

3 ( x + 1 ) = -2 ( x - 1 ) - 4

distibute

3x + 3 = -2x + 2 - 4

simplify

3x + 3 = -2x - 2

inverse operations

3x + 3 = -2x - 2

the answer is d

the equation you need to solve is:

5x + x-12 = 90

         +12    +12

6x=102

now, divide by 6 and you get x= 17

17-12 = 5

17 x 5 = 85

Answer:

2.75

Step-by-step explanation:

Here, we want to find which part of the formula corresponds to the cost of movie tickets in 1980

The expression to find the cost is

2.75 + 0.10x

Now, x is the time since 1980

1980 is thus the starting position. The value of x at this point is 0, we simply thus make a substitution;

2.75 + 0.1(0)

=

2.75

The interpretation of the given model is required.

The cost of a movie ticket in the year 1980 was $2.75.

The given expression is

[tex]y=2.75+0.1x[/tex]

The point slope form of a line is

[tex]y=mx+c[/tex]

where,

m = Slope

c = Y intercept

The cost of movie ticket increases by $0.10 every year after 1980.

Here, [tex]x[/tex] is the number of years that have passed after 1980.

So, when [tex]x=0[/tex] it will correspond to the cost of ticket in 1980.

[tex]y=2.75+0.1\times 0\\\Rightarrow y=2.75[/tex]

The cost of a movie ticket in the year 1980 was $2.75.

-4x+y=-22

Step-by-step explanation:

-4x +y= -22  is the equation of this line in Standard Form .

What is in slope-intercept form?

m = 4

the point =  (5, -2)

the equation of this line

          y - y₁ = m ( x - x₁)

          y - ( -2 ) = 4 ( x - 5 )

          y + 2 = 4( x - 5 )

           y + 2 = 4x - 20

Answer:

4.8 x 10^9

Step-by-step explanation:

E9 is 10 raised to the power of 9

Scientific notation requires you to write a number from 1 to 10 then multiply it by 10 raised to a number x.

In this case:

4.8E9 = 4,800,000,000

Number between 1 and 10 = 4.8

Number of zeroes = 8 but because you have to multiply 4.8 times 10 to get 48 the answer is 4.8 x 10^9... so one extra 10... 1+8=9

In Mathematics, you must have learned about different types of equations. Here, we are going to discuss the difference between linear and nonlinear equations. The difference between them described here with the help of definitions and examples.

We come across a lot of equations while solving maths problems. Some equations include only numbers and some consist of only variables and some consists of both numbers and variables. Linear and nonlinear equations usually consist of numbers and variables.

Definition of Linear and Non-Linear Equation

Linear means something related to a line. All the linear equations are used to construct a line. A non-linear equation is such which does not form a straight line. It looks like a curve in a graph and has a variable slope value.

The major difference between linear and nonlinear equations is given here for the students to understand it in a more natural way. The differences are provided in a tabular form with examples.

What is the difference between Linear and Nonlinear Equations?

To find the difference between the two equations, i.e. linear and nonlinear, one should know the definitions for them. So, let us define and see the difference between them.

Linear Equations  

Non-Linear Equations

It forms a straight line or represents the equation for the straight line It does not form a straight line but forms a curve.

It has only one degree. Or we can also define it as an equation having the maximum degree 1. A nonlinear equation has the degree as 2 or more than 2, but not less than 2.

All these equations form a straight line in XY plane. These lines can be extended to any direction but in a straight form. It forms a curve and if we increase the value of the degree, the curvature of the graph increases.

The general representation of linear equation is;

y = mx +c

Where x and y are the variables, m is the slope of the line and c is a constant value.

The general representation of nonlinear equations is;

ax2 + by2 = c

Where x and y are the variables and a,b and c are the constant values

Examples:

10x = 1

9y + x + 2 = 0

4y = 3x

99x + 12 = 23 and

Examples:

x2+y2 = 1

x2 + 12xy + y2 = 0

x2+x+2 = 25

Note:

The linear equation has only one variable usually and if any equation has two variables in it, then the equation is defined as a Linear equation in two variables. For example, 5x + 2 = 1 is Linear equation in one variable. But 5x + 2y = 1 is a Linear equation in two variables.

Let us see some examples based on these concepts.

Solved Examples

Example: Solve the linear equation 3x+9 = 2x + 18.

Solution: Given, 3x+9 = 2x + 18

⇒ 3x - 2x = 18 - 9

⇒ x = 9

Example: Solve the nonlinear equation x+2y = 1 and x = y.

Solution: Given, x+2y = 1

x = y

By putting the value of x in the first equation we get,

⇒ y + 2y = 1

⇒ 3y = 1

⇒ y = ⅓

∴ x = y = ⅓

What is the key difference between non-linear and linear equations?

A linear equation is used to represent a straight line in a graph, whereas non-linear equations are used to represent curves.

How does the graph of linear and non-linear equations look?

A linear equation graph is a constant slope whereas the graph of the non-linear equation shows the variation in slope at different points.

How is the linear equation represented? Give an example.

The general representation of linear equation is y = mx+c,

where m = slope of the line

x and y are the variables

c is the intercept (constant value)

Example: 2x+y=1

y=-2x+1

How is the nonlinear equation formed?

A non-linear equation is generally given by ax2+by2 = c

where x and y are variables

a,b and c are constant values.
