6x + 7 = 13x - 9
7 + 9 = 13x - 6x
16 = 7x
16/7 = x....or 2 2/7 = x
Answer:
20
Step-by-step explanation:
when a letter and a number are next to each other u have to multiply, so x is 5 so 3 x 5 is 15. 15 plus 5 is 20 so 20 is ur answwer
Answer:(-4,0)
Step-by-step explanation:
Given
Point A (6,-4)
Reflection of Point A about line y=-2 is
A' (6,0)
If any Point is reflected about any line y=constant then its x coordinate remains same
Now reflection of Point A' about x=1 is
A'' (-4,0)
If any point is reflected about line x=constant then its y coordinate remains same
Mathematical proofs are important because they help to explain concepts. They also serve as concrete validation for a mathematical result or statement.
- In geometry, an incorrect conclusion within a proof might lead to wrong estimations of size, length, and other spatial properties.
- Algebra, topology, arithmetics, calculus, and statistics are some other branches of mathematics. In statistics, an incorrect conclusion within a proof might lead to the wrong interpretation of bulky data. Statistical properties like the mean, median, and mode can be misinterpreted.
- Businesses that rely on statistics for production and forecasting might be affected.
<h3>What is a Mathematical proof?</h3>
A proof in mathematics is a number of conclusions that lead to the justification of a final statement.
Having incorrect mathematical proofs can be dangerous because it will cause the misinterpretation of concepts and the obtaining of wrong results.
