Order of operation and mathematical con vent ion

Answers

PEMDAS - Parenthesis, exponent, multiply, divide, add, subtract

Final answer:

In mathematics, the order of operations and mathematical conventions are vital to ensure the correct solution of equations. This includes principles like scientific notation for handling large or small numbers, and dimensional analysis for ensuring the validity of equations involving different units of measurement.

Explanation:

The order of operations and mathematical convention are fundamental in accurately solving mathematical equations or expressions. This involves following certain rules, such as the use of scientific notation or the principles of dimensional analysis, to ensure equations and operations are performed correctly and yield valid results.

Take for example scientific notation, used for expressing very large or small numbers. When multiplying two numbers expressed in scientific notation, the process is simplified: you multiply coefficients and add exponents. E.g., (3 × 105) × (2 × 109) = 6 × 1014.

Alternatively, dimensional analysis is a technique used to check the validity of equations involving mathematical operation on quantities. It works on the premise that the units of these quantities have to undergo the same mathematical operations as their numbers. This ensures consistency and coherence of dimensions and units in the expression or equation, preventing impossible situations such as adding length to time.

If m∠1 = 3x, m∠3 = 2x + 20 and m∠5 = 30, what is the value of x?

Answers

m∠2 = 180 - m∠1 = 180 - 3x   [supplementary angles]

In a triangle, the three interior angles always add to 180° ⇒
m∠2 + m∠3 + m∠5 = 180
180-3x + 2x+20 + 30 = 180
230 - x = 180
x = 230 - 180
x = 50

Answer:

y = 3x + 3

Step-by-step explanation:

y = mx + b

m = slope

m = y2-y1/x2-x1 = 9-6/2-1 = 3/1 = 3

m = 3

b = y-intercept

b = 3

Answer:

The answer would be y = 3x + 3.

Answer:

y = -2x + 4

Explanation:

Pick two points from the line: (1, 2), (0, 4)

Slope intercept form: y = mx + b

Find 'm': 2 - 4 = -2

Find 'b': 4

Insert numbers into equation: y = -2x + 4

Answer:

y= -2x + 4
