They would be the same being 250$ on the 5th month. The way I solved this is I made a equation for each being ( 10x + 200 = ) and ( 30x + 100 = ) If you put 5 in the place of x, you will multiply it by the 10 or 30 and add the original cost put in.

Which term best describes the point where the three altitudes of a triangle intersect
kolezko [41]
Hi!

The point where the three altitudes of a triangle intersect is called the orthocenter.

Altitudes are lines which pass through the the vertex of a triangle, and bisect the other side.

There are three other points like an orthocenter; an incenter, a circumcenter, and a centroid. They're where the angle bisectors, the perpendicular bisectors, and the medians of a circle intersect, respectively.

Hope this helped!
