So basically you can add it with column addition or just simply break it down

Think about it lets break down 12 i got 10 and 2
then you can add it more easily

you could do 5019+10=519
then add 2 to get 521

Or you could do this

509
  12 +
______
521

so basically toy add 9+2 to get 11
then you carry the 1
then you do 1+1=2
then the 5 is left

so finally you get left with 512

You always work from left to right

Which is an equation of a line that has a slope of -1/3 and passes through the point (-5, 2)?
kramer

Answer:

y= -⅓x +⅓

Step-by-step explanation:

The equation of a line is usually written in the form of y=mx+c, where m is the gradient and c is the y-intercept.

This form is also known as the point-slope form.

Since the slope is given to be -⅓, m= -⅓.

y= -⅓x +c

To find the value of c, substitute a pair of coordinates into the equation.

When x= -5, y=2,

2= -⅓(-5) +c

2 =  \frac{5}{3}  + c \\ c = 2 -  \frac{5}{3}  \\ c =  \frac{1}{3}

Thus, the equation of the line is y= -⅓x +⅓.

Find the distance between the two points (-2,-6) and (0,5).
HACTEHA [7]

Answer: OPTION B

Step-by-step explanation:

You can find the distance between two points by using the following formula:

d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}

Given the points  (-2,-6) and (0,5), you can identify that:

x_2=-2\\x_1=0\\\\y_2=-6\\y_1=5

Therefore, substituting values, you get that the distance between those points is:

 d=\sqrt{(-2-0)^2+(-6-5)^2}\\\\d=5\sqrt{5}

Find the slope of the given line, if it is defined. 2x + 1 = 0
svlad2 [7]

Given :

A line 2x + 1 =0 .

To Find :

The slope of the given line .

Solution :

We know , slope of line is given by the tangent of the angle between the x-axis and the line .

Now, for line 2x + 1 =0 i.e x=\dfrac{-1}{2} .

The line is perpendicular to x-axis and cuts the x-axis at \dfrac{-1}{2} .

Therefore , the angle between the line and x-axis is 90^o .

So , slope m=\tan\ 90^o i.e undefined .

Therefore , the slope of given line is not defined .

Hence , this is the required solution .
