Can you find the distance between two points using absolute value
EleoNora [17]

This depends. The way you do this is by taking these two points and by adding their absolute values together, this therefore finds their difference. This only works if one number is positive and one in negative. If two numbers are on the same side of the number line you CANNOT find their difference with absolute value.

Hope this helps, if not, comment below please!!!!

Answer:

42

Step-by-step explanation:

Hey There!

Angle 3 and Angle 4 are a pair of supplementary angles meaning that added together they will equal 180

So if angle 4 is given to find angle 3 all we have to do is subtract the angle that is given from 180

180-138=42

Therefore angle 3 = 42

If you were to make a line graph which two numbers would be 3.275 be in between if you are trying to round it to the nearest who
alina1380 [7]
Whole number would be 3, so the middle would be 1.5
Nearest tenth would be 3.3, so the middle would be 1.65
Nearest hundredth would be 3.28, so the middle would be 1.64
(I'm not sure if that's what you meant)

Line A is represented by the following equation: x + y = 2
Orlov [11]

Answer:

ax+ay=k; a\ne0, k\ne2a; line D in the options.

Step-by-step explanation:

The set of equations has no solutions if the two lines are parallel. A quick way to create a parallel line is to solve for y, put it in slope-intercept form. Else, as long as the cofficient of x and y are in the same ratio (in this case 1:1), the two lines are parallel, you just have to be careful not to pick the same line again!

The condition a\ne 0 makes sure you are still getting lines (else you would get rid of both x and y); the condition k\ne 2a makes sure you're not picking line A again, just written in a different form.

Now that we have the options:

A and C have a different ratio for the coefficient of x and y (2:1 and 1:2) so are not good.

Choice B is just a more complicated way to write the same line, you can see by dividing both sides by 2 and get back x+y=2.

Line D is correct.
