Simplify fully 4x + 3y -2 + 2x - 8y -6

Answers

Hi, Amyleighx!

First we want to identify any common factors.
4x+3y-2+2x-8y-6
3y-8y=-5y
4x+2x=6x
-2-6=-8
-5y+6x-8

I hope this helps;)
combine like terms. you can combine 4x and 2x, so that is 6x. now combine 3y and-8y and get -5y. combine-2 and -6 and get -8. now put ur terms together. 6x-5y-8

13/52 in simplest form

Answers

13/52 

13/13 = 1
52/13 = 4

1/4 is the most simple form
MattaMillion, the simplest form for 13/52 is 1/4. The greatest common factor between 13 and 52 is 13, so we divide 13 and 52 by 13 to get 1/4.

Which statement is an axiom of Euclidean geometry? If two lines intersect, their intersection is a plane. If two planes intersect, their intersection is a point. Space contains at least three points that do not lie on the same line. If two points lie in a plane, the line containing those points lies in the same plane. Given any two points A and B, there are exactly two lines that contain those points

Answers

Answer:

The axiom is:

If two points lie in a plane, the line containing those points lies in the same plane.

Step-by-step explanation:

Euclid's method consists in assuming a small set of intuitively appealing axioms, and deducing many other propositions (theorems) from these.

Euclid axioms seemed to be so true or obvious that any theorem proved from them was deemed true in an absolute.

The statement that is an axiom of Euclidean geometry is:

If two points lie in a plane, the line containing those points lies in the same plane.
if 2 points lie in a plane, the line containing those opints lies in the same plane

Answer:

Coordinate geometry is one of the most important and exciting ideas of mathematics. In particular it is central to the mathematics students meet at school. It provides a connection between algebra and geometry through graphs of lines and curves. This enables geometric problems to be solved algebraically and provides geometric insights into algebra.

The invention of calculus was an extremely important development in mathematics that enabled mathematicians and physicists to model the real world in ways that was previously impossible. It brought together nearly all of algebra and geometry using the coordinate plane. The invention of calculus depended on the development of coordinate geometry.

A car dealership lowered all of its car prices by 15%. Given the above information, what was the original price of a car now priced at £9500?

Answers

9,500 is 15% less than the original price.
So it must be 85% of the original price.

£9,500 = 0.85 P

Divide each side by 0.85 :

P = £9,500 / 0.85 = £11,176.47
the original price would be 9500+(0.15*9500)=10925

Which value of x makes the open sentence true?
5x – 6 = x + 12

Answers

The way we approach a problem like this is by using a technique called "collecting like terms".
This means that we want to put all of the values with an "x" on one side and all of the normal numbers on the other. For this particular problem we can do this as follows:
5x - 6 = x + 12
Now move the (- 6) to the right side of the equation by adding 6 to both sides:
=> 5x = x + 12 + 6
Now move the (x) to the left side of the equation by subtracting (x) from both sides:
=> 5x - x = 12 + 6
Now perform the simple arithmetic on both sides:
=> 4x = 18
Now remove the 4 from in front of the (x) by multiplying the whole equation by (1/4)
=> x = 18/4
Therefore to make your open sentence true, x must equal 18/4, or to simplify, 9/2, or as a decimal, 4.5. I hope this helped, and remember to try and understand not just the answer, but the maths involved in getting to the answer too :))
