Standard form is ax + by = c y = 2/7x - 4 y + 4 = 2/7x 4 = 2/7x - y Multiply everything by 7 to get rid of fraction. 28 = 2x - 7y Answer: 2x - 7y = 28

Which dimensions cannot create a triangle?
zavuch27 [327]
Angles that create a triangle always add up to 180. 

To find sides that create triangles, we have to use the Triangle Inequality Theorem.
It's where side A + B will <em>always</em> be greater than side C
and B + C will always be greater than side A
<em>and</em> A + C will always be greater than side B.

So let's check all of these answers and pick the one that's incorrect.

A.
10 + 25 + 145 = 180?
Correct!

B. 
9 + 15 > 9?
Correct!
15 + 9 > 9?
Correct!
9 + 9 > 15?
Correct!

C. 
40 + 70 + 60 = 180?
Incorrect! 40 + 70 + 60 = 175 which is less than 180.

The answer is three angles measuring 40 m, 70 m, and 60 m.

Hope this helped! If you have anymore questions or don't understand, please comment or DM me. :)

What is the length of the radius of a circle with a center at 2 + 3i and a point on the circle at 7 + 2i?
dem82 [27]
You can calculate the difference/vector of both points:
7+2i-(2+3i)=5-i
then calculate the magnitude/length like pythagoras
radius=\sqrt{5^2+(-i*-i)}\\=\sqrt{5^2+i^2}\\=\sqrt{5^2-1}\\=\sqrt{24}\\=\sqrt{4*6}\\=2*\sqrt{6}
