To find:

Which of the following options is an equation.

Solution:

A mathematics or algebraic statement which represents that the values of two mathematical expressions are equal, is called an equation.

In option A,

[tex]5-4=9[/tex]

[tex]1\neq 9[/tex]

LHS≠RHS. So, it is not an equation.

In option B and C,

[tex]5+4=9[/tex]

[tex]9=9[/tex]

LHS=RHS. Both are equations.

In option D,

[tex]5+4-9[/tex]

This is an expression, not an equations.

Therefore, the correct options are B and C.

Answer:

y-intercept and slope

Step-by-step explanation:

When we graph a line using slope and y-intercept, the first point that you graph is  y-intercept.

What is Mathematical equation ?

By definition, an equation is a mathematical statement made up of two expressions linked by an equal sign. In other words the equation represents the graph between x and y that is for each value of x there exist one value of y.

So, When we graph a line using slope and y-intercept, the first point that you graph is  y-intercept.

Let, consider the equation of y = mx+c, where, m is the slope of line and c is the y - intercepts. So to draw the graph firstly we find the two points to connect the line in which first is y-intercepts by putting x=0 in the given equation.

Therefore, When we graph a line using slope and y-intercept, the first point that you graph is y-intercept.

Algebra is the branch of mathematics that helps in the representation of problems or situations in the form of mathematical expressions. It involves variables like x, y, z, and mathematical operations like addition, subtraction, multiplication, and division to form a meaningful mathematical expression. All the branches of mathematics such as trigonometry, calculus, coordinate geometry, involve the use of algebra. One simple example of an expression in algebra is 2x + 4 = 8.

Given:

Greetings from Brasil...

Let's add all the values on one side and make it equal to the sum of all the other values on the other side

(- X) + (- X) + (- X) + (- X) + (- X) + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1 + 1  =  X + X + X + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1) + (- 1)

- 5X + 12 = 3X - 8

- 5X - 3X = - 8 - 12

- 8X = - 20    x(- 1)

8X = 20

X = 20/8

or X = 2.5

Your answer is 6170.

So, we have the equation..

[tex]\frac{3}{16}[/tex]

Step-by-step explanation:

We do the division first because of PEMDAS.

Apply the fraction division rule: [tex]\frac{a}{b}\div \frac{c}{d}=\frac{a}{b}\times \frac{d}{c}[/tex]

Therefore,

[tex]\frac{5}{8}-\frac{1}{4}\div \frac{4}{7}=\frac{5}{8}-\frac{1}{4}\times \frac{7}{4}[/tex]

Multiply the two fractions:

[tex]\frac{5}{8} -\frac{1\times \:7}{4\times \:4}[/tex]

[tex]\frac{5}{8}-\frac{7}{16}[/tex]

The LCM of the denominators (8 and 16) is 16.

Adjust fractions:

[tex]\frac{10}{16}-\frac{7}{16}[/tex]

Subtract:

[tex]\frac{10-7}{16}[/tex]

Answer:  $27.35  

Step-by-step explanation:

First let's  find the variables.We will use x to represent the number of subscription sold and y we will represent the amount of money you will get paid.

So we know that , if you sell One You will get $1.25  so we could represent it by the point  (1,1.25) .

Now the second statement says that if you sell an additional subscription you will get an additional 15 cents or $0.15.Which means if you sell the second subscription, you will get  $1.40  because it is an additional 15 cents. We can also represent that by the point (2,1.40)  

Now using the two points come up with an equation.  

(1,1.25)

(2,1.40)    Find the slope and y intercept.

TO find the slope find the difference between y and divide it by the difference in x.

1.25 - 1.40 = 0.15

1 - 2  =   1  

0.15/ 1 =  0.15  So the slope is 0.15

Now use the point to find the y intercept. using the y-intercept formula,  

y = mx + b  

1.25 = 0.15(1) + b

1.25 =  0.15 + b

-0.15     0.15

 b = 1.1  

We can now write the equation  y = 0.15x + 1.1 to represent the whole situation where  x is still the number of subscriptions sold and y is the money you will get paid. Now to find how much you will earn for 175 subscriptions, you will input 175 for x and solve for y.

y = 0.15(175) + 1.1

y = 26.25 + 1.1

 y = 27.35

So you will earn $27.35  for 175 subscriptions

The answer should be 10p - 4.

An expression is a number, or a variable, or a combination of numbers and variables and operation symbols.

Now the given expression is,

3p + 5 + 7p - 9

To solve this taking alike terms together.

3p + 7p + 5 - 9

Thus, we have

Variables = 3p + 7p = 10p

Constants =  5 - 9 = -4

Thus, the expression becomes,

3p + 5 + 7p - 9 = 10p - 4

So, this is the required answer of the given expression.

Thus, the answer should be 10p - 4.
