Line segment AB has endpoints A(1, 4) and B(6, 2). Find the coordinates of the point that divides the line segment directed from
VMariaS [17]

let's say that point is point C, thus


\bf ~~~~~~~~~~~~\textit{internal division of a line segment}\\\\\\A(1,4)\qquad B(6,2)\qquad\qquad \stackrel{\textit{ratio from A to B}}{2:3}\\\\\\ \cfrac{A\underline{C}}{\underline{C} B} = \cfrac{2}{3}\implies \cfrac{A}{B} = \cfrac{2}{3}\implies 3A=2B\implies 3(1,4)=2(6,2)\\\\[-0.35em]~\dotfill\\\\C=\left(\frac{\textit{sum of "x" values}}{\textit{sum of ratios}}\quad ,\quad \frac{\textit{sum of "y" values}}{\textit{sum of ratios}}\right)\\\\[-0.35em]~\dotfill


\bf C=\left(\cfrac{(3\cdot 1)+(2\cdot 6)}{2+3}\quad ,\quad \cfrac{(3\cdot 4)+(2\cdot 2)}{2+3}\right)\implies C=\left(\cfrac{3+12}{5}~,~\cfrac{12+4}{5} \right)\\\\\\C=\left( \cfrac{15}{5}~,~\cfrac{16}{5} \right)\implies C=\left( 3~,~3\frac{1}{5} \right)

Is { (8,5) , (7,5) , (6,2) , (8,3) , (1,-4), (-4,6)} a function? why?
DIA [1.3K]

Answer:

No.  because you have One domain value that  says 2 different numbers

Step-by-step explanation:

functions cannot have  f(8) = 5  and f(8) = 3  at the same time

because  then f(8)  is not equal to f(8)  it cannot be confusing.
