Write 4–6 sentences explaining why it is important to have precise definitions
andreyandreev [35.5K]

Answer and Step-by-step explanation:

Areas of mathematics, and give a precise definition of each.

Sol: importance: mathematics can be tricky, so precise definitions are essential. Without them, there can be confusion, which will generate the wrong answer more often than not.  It teaches the students exactly how to use formulas and under what condition a mathematical statement is true.

Some words related to geometry that are quite hard to define precisely are the line, the plane, and the point. In mathematics, the unit square is area one and any other shape.

Which table has a constant of proportionality between y and x of 12?
konstantin123 [22]

Answer:

Table A

Step-by-step explanation:

If you do delta method (Change in y and x)

For example, 120-24

______ = 96/8

10-2

Then you divide both the numerator and denominator by the denominator (which is 8) and that gets us to 12 as our answer. Do the same method for all of the numbers in table A.

Ps: I hope that I was helpful, and you are welcome.

-2x - 18 = 611-2x) + 4x
Serhud [2]

Answer:

x = (-629)/4

Step-by-step explanation:

Solve for x:

-2 x - 18 = 4 x - 2 x + 611

4 x - 2 x = 2 x:

-2 x - 18 = 2 x + 611

Subtract 2 x from both sides:

(-2 x - 2 x) - 18 = (2 x - 2 x) + 611

-2 x - 2 x = -4 x:

-4 x - 18 = (2 x - 2 x) + 611

2 x - 2 x = 0:

-4 x - 18 = 611

Add 18 to both sides:

(18 - 18) - 4 x = 18 + 611

18 - 18 = 0:

-4 x = 611 + 18

611 + 18 = 629:

-4 x = 629

Divide both sides of -4 x = 629 by -4:

(-4 x)/(-4) = 629/(-4)

(-4)/(-4) = 1:

x = 629/(-4)

Multiply numerator and denominator of 629/(-4) by -1:

Answer: x = (-629)/4
