Which Greek geometer founded a philosophical society that developed its self to the study of mathematics

Please help! you will get 10 points tyy

nignag [31]

Answer:

y=-2x-1

Step-by-step explanation:

First we need to know the slope-intercept equation:

y=mx+b

m: slope

b: y-intercept

First we find the slope:

Slope = (y₂-y₁)/(x₂-x₁)

Use any two x and y values on the table:

Slope = [-5-(-3)]/(2-1) = -2/1 = -2

Now we find the y-intercept:

y=mx+b

y=-2x+b

We plug in a pair of x and y values into the equation:

-3=-2(1)+b

-3=-2+b

b=-1

So the slope-intercept equation is:

y=-2x-1

Describe the location of the sum, relative to p, on a number line P+(-2)

il63 [147K]

Answer:

The location of the sum is 2 units before P (left to P)

Step-by-step explanation:

* Lets describe the number line

- A number line is a horizontal straight line with numbers placed at

an equal units

- A number line can be extended infinitely to the left and to the right

- A number line represents both positive and negative integers

- The numbers come on it from left to right

- The negative numbers come on the left of zero and the positive

numbers come on the right of zero

- Ex: -5 , -4 , -3 , -2 , -1 , 0 , 1 , 2 , 3 , 4 , 5 part of the numbers on the

number line

- To add numbers on the number line we start from first number of

the addition and if this number is added by a positive number we

go to right , if the number is added by a negative number

we go to left

- Ex: 5 + 3 ⇒ go from 5 to the right 3 units, then your position is at 8

2 + (-3) ⇒ go from 2 to the left 3 units then your position is at -1

* Now lets solve the problem

- The sum of P + (-2)

∵ Your location is P

∵ You will add P by (-2)

- Negative number means you go to the left

∴ Your position will be before P by two units

∴ The location of the sum is 2 units before P (left to P)

What is the area of a shape with points a 5 -8 b 11, -8 c 11,0 d 6,-3 e 4,-3

Dmitriy789 [7]

Answer:

Area of the given figure is 51.5 square units.

Step-by-step explanation:

Area of rectangle OCBH = Length × width

= 11 × 8

= 88 square units

Area of trapezoid OGEF = $\frac{1}{2}(b_1+b_2)\times h$

= $\frac{1}{2}(\text{GE+OF)}\times (\text{OG})$

= $\frac{1}{2}(3+6)\times 4$

= 18 units²

Area of trapezoid GCDE = $\frac{1}{2}(\text{GC+DE)}\times (\text{GE})$

= $\frac{1}{2}(7+2)\times 3$

= 13.5 units²

Area of triangle AFH = $\frac{1}{2}(\text{Base})\times (\text{Height})$

= $\frac{1}{2}(5)(2)$

= 5 units²

Area of polygon ABCDEF = Area of rectangle CBHO - (Area of trapezoid OGEF + Area of trapezoid GCDE + Area of triangle AFH)

= 88 - (18 + 13.5 + 5)

= 88 - 36.5

= 51.5 units²

Therefore, area of the given polygon is 51.5 units²

Solve for x 3(x+2) + 4(x-5)=10

Fittoniya [83]

Answer:

x= 3.43

Step-by-step explanation:

First, use the distributive property and multiply 3 by x and 3 by 2:

3x + 6

next use the distributive property again and multiply 4 by x and -5:

4x - 20

Combine Like terms: 3x + 6 + 4x - 20

3x + 4x = 7x

6 - 20 = -14

Now Add 14 to both sides: 7x - 14 = 10

10 + 14 = 24

Now divide 7 by both sides: 7x = 24

24 / 7 = 3.428571429 = 3.43

Boris filled his gas tank three times last week. Here are the amounts of gas he bought (in gallons).

slega [8]

Answer:

30.04

Step-by-step explanation:

You could do this the simple way which is to first grab two numbers in any order and add them together, and after you do that you can add the result to the remaining number or numbers that remain. 9.94 plus 1 is 10.94, and 10.94 plus 19 is 29.94, lastly the .1 from the 19 which finally leads us to the answer of 30.04 gallons that Boris bought last week
