Mathematics
1 answer:
Valentin [98]3 years ago
4 0

Answer:

Zero

Step-by-step explanation:

Because integers are equal in magnitude but opposite in sign, therefore they will cancel out each other leaving zero as answer.

- 20  - 19 - 18 - 17 - 16 - 15.. - 1 + 0 +  \\ 1 ..... + 15 + 16 + 17 + 18 + 19 + 20 \\  = 0

Given the points (3, 2) and (6, 4), which of the following are true about the line passing through these points? The line has a
Ad libitum [116K]

Answer:

The slope is 2/3 and the function is y=2/3x  which is a direct variation function.

Step-by-step explanation:

To find the slope of a line between two points, we use the equation

m = (y2-y1)/ (x2-x1)

where (x1,y1) and (x2,y2) are the two points

m= (4-2)/(6-3)

  = 2/3

The slope of the line is 2/3

The equation of the line is

y-y1 = m(x-x1)

y-2 = 2/3(x-3)

Distribute

y-2 = 2/3x -2

Add 2 to each side

y-2+2 = 2/3x -2+2

y = 2/3x

This is a direct variation function

Let x = -6

y = 2/3(-6)

y = -4

(-6,-4)

The product of three and a squared number is twice the sum of the number and four
Mamont248 [21]
From the text of the task we can write the equation:


3 x^{2} =2(x+4)\\&#10;\\&#10;3x^2=2x+8\\&#10;\\&#10;3x^2-2x-8=0\\&#10;\\&#10;\Delta=(-2)^2-4.3.(-8)=4+96=100\\&#10;\\&#10;x=\frac{2 \pm\sqrt{100}}{2.3}=\frac{2 \pm10}{6}\\&#10;\\&#10;x_1=\frac{2-10}{6}=-\frac{8}{6}=-\frac{4}{3}\\&#10;\\&#10;x_2=\frac{2+10}{2.3}=\frac{12}{6}=2
