What is Trigonometry?

Trigonometry is a branch of mathematics that studies relationships between side lengths and angles of triangles.

The given quadrilateral is a rectangle.

In rectangle each angle has 90 degrees.

So equate 13x+12 and 90 degrees to get x

13x+12=90

Subtract 12 from both sides

13x=90-12

13x=78

Divide both sides by 13

x=6

Hence, the value of x in the rectangle is 6.

Fraction Form

25/33

Decimal Form

0.75

Step-by-step explanation:

First, convert the mixed fraction into an improper fraction, so it would look like:

-5/3 / (-11/5)

Next, divide. Remember, when multiplying fractions all you do is flip the one in parantheses and make both of them positive, so it would look like:

5/3 x 5/11

Finally, multiply so you do the two top numbers which is 5 x 5= 25 and the two bottom numbers so 11 x 3 is 33. Then your final answer is 25/33

To find the slope of the line that contains (2, -10) and (-4, 2).

What is the slope of the line?

The slope of the line is a tangent angle made by line with horizontal. i.e. m =tanx where x in degrees.

What is simplification?

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
The slope of any line is given as if two points are given,
m = [y₂ - y₁] / [x₂ - x₁]
the slope of the line that contains (2, -10) and (-4, 2)
m = [2 + 10 ] / -4 - 2
m = 12 / -6
m = -2

Why is it important to understand how variables work, inequalities, and basic awareness of exponents before starting algebra?

Answers

Answer:

It is important because they are the basics of algebra. Almost every algebraic problem you will ever solve is based on these fundamental properties. In equations, we almost never know every part of it so we will need variables to substitute the unknown amount in an equation. Variables are used for basically every equation/problem in algebra. Inequalities are not as important as variables but are still really important. Inequalities are basically comparing numbers. And in algebra when they add variables into an inequality, the inequality will help lower the number of possible values of said variable. And exponents are just a basic operation in algebra. Just like learning addition and subtraction. It is like a quicker and less complicated way of multiplying numbers.

P = 586 / ( 0.03 × 6 ) = 3255.5555555556

P = $ 3,255.56

Solve the system of linear equations by elimination. 11x−20y=28 , 3x+4y=36

Answers

X= 8 Y= 3 math papa can help you and show you steps

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

The value of x is 8.

The value of y is 3.

What is an equation?

An equation is a mathematical statement that is made up of two expressions connected by an equal sign.

Example:

2x + 4 = 7 is an equation.

We have,

11x - 20y = 28 ____(1)

3x + 4y = 36 _____(2)

Now,

Multiply 5 on (2).

11x - 20y = 28

15x + 20y = 180

26x          = 208

This means,

x = 208/26

x = 8

Now,

11x - 20y = 28

11 x 8 - 20y = 28

88 - 20y = 28

88 - 28 = 20y

y = 60/20

y = 3

Thus,

The value of x is 8.

The value of y is 3.
