Using the slope and the y-intercept graph the line represents by the following equation then select the correct graph 2y + 4 =0

Mathematics
1 answer:
dybincka [34]3 years ago
8 0

Answer:

Step-by-step explanation:

2y + 4 = 0               <em>subtract 4 from both sides</em>

2y = -4       <em>divide both sides by 2</em>

y = -2

The slope-intercept form of an equation of a line:

y = mx + b

m<em> - slope</em>

b<em> - y-intercept → (0, </em><em>b</em><em>)</em>

In the equation

y = -2

<em>slope: </em><em>m = 0</em>

<em>y-intercept: </em><em>b = -2 → (0, -2)</em>

<em />

<em>y = -2 - it's a horizontal line</em>

Find an equation for the line with the given properties. Express your answer using either the general form or the​ slope-interce
Vladimir [108]

Answer:

y = 7x

Step-by-step explanation:

Complete question:

Find an equation for the line with the given properties. Parallel to the line 7x - y = -7; containing the point (0,0)

The equation of a line in point-slope form is expressed as;

y - y0 = m(x-x0)

(x0, y0) = (0,0)

Given the equation of the line as 7x - y = -7;

Rewrite and get the slope

-y = -7x - 7

y = 7x+7

Get the slope

mx = 7x

m = 7

Substitute into the equation

y - 0 = 7(x - 0)

y = 7x

Hence the required equation is y = 7x

Find the number of positive numbers less than 2020, which can not be written as the sum of six consecutive positive numbers.
sveta [45]

Answer: 334

Step-by-step explanation:

6 consecutive numbers can be written as:

n, n+1, n+2, n + 3, n + 4, n + 5,

The addition of those 6 numbers is:

n + n+1 + n+2 + n + 3 + n + 4 + n + 5

6n + 1 + 2 + 3 + 4 + 5 = 6n + 15

Let's find the maximum n possible:

6n + 15 = 2020

6n = 2020 - 15 = 2005

n = 2005/6 = 334.16

The fact that n is a rational number means that 2020 is can not be constructed by adding six consecutive numbers, but we know that with n = 334 we can find a number that is smaller than 2020, and with n = 335 we can found a number bigger than 2020.

So with n =  334 we can find one smaller.

6*334 + 15 = 2019

and we can do this for all the values of n between 1 and 334, this means that we have 334 numbers less than 2020 that can be written as a sum of six consecutive positive numbers.
