What point divides the line segment between (10,-2) and (-6,6) into a ratio of 5:3
olganol [36]

Answer: (0,3)

Step-by-step explanation:

You follow the formulas to find the x and y of the dividing points.

Xp= x1+ a/a+b (x2-x1)

Xp= 10+5/5+3(-6-10)

Xp=10+5/8(-16)

Solve the problem above and you end up with “0” as your x.

Yp= y1+ a/a+b (y2-y1)

Yp= -2+ 5/8 (6+2)

Yp= -2+ 5/8 (8)

Solve this problem above and you end up with “3” as your y. Therefore, the point that divides the line segment between (10, -2) and (-6,6) into a ratio of 5:3 is (0, 3).

Help help needed for composition of function
dimulka [17.4K]

Answer:

\circledast \ \ f\circ f\left( x\right) = x

\circledast \ \ g\circ g\left( x\right)  =4x - 21

Step-by-step explanation:

f(x)=\frac{5}{2x}

g(x) = 2x - 7

==============

f\circ f\left( x\right)  =\frac{5}{2\left( f\left( x\right)  \right)  }

             =\frac{5}{2\left( \frac{5}{2x}  \right)  }

             =\frac{5}{\left( \frac{5}{x}  \right)  }

             =5\times\frac{x}{5}

             =x

_____________

g\circ g\left( x\right)  =2(g(x)) - 7

            = 2(2x - 7) - 7

           = 4x - 14 - 7

           = 4x - 23
