6. AB has coordinates A(-5,9) and B(7,-7). Points P, Q, and T are collinear

MrRissso [65]

Answer:

C) QT

Step-by-step explanation:

We must first find the coordinates of C(x,y) which divides AB in the ration m:n=3:2.

We use the formula

$x=\frac{mx_2+nx_1}{m+n}$

and

$y=\frac{my_2+ny_1}{m+n}$

We plug in the coordinates of A(-5,9) and B(7,-7) and m=3, n=2 to get:

$x=\frac{3*7+2*-5}{3+2}$

$x=\frac{21-10}{5}$

$x=\frac{11}{5}$

and

$y=\frac{3*-7+2*9}{3+2}$

$y=\frac{-21+18}{5}$

$y=-\frac{3}{5}$

C has coordinates $(\frac{11}{5},-\frac{3}{5})$

The line segment that contains C is $QT$

What is K+(-5/3)=-44/3

Natalija [7]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \sf k = - 13}}}}$

Step-by-step explanation:

$\sf{k + ( - \frac{5}{3} ) = - \frac{44}{3} }$

When there is a ( + ) in front of an expression in Parentheses, there is no need to change the sign.

That means the expression remains the same.

⇒ $\sf{k - \frac{5}{3} = - \frac{44}{3} }$

Move 5/3 to right hand side and change it's sign

⇒ $\sf{k = - \frac{44}{3} + \frac{5}{3} }$

While performing the addition or subtraction of like fractions , you just have to add or subtract the numerator respectively in which the denominator is retained same.

⇒ $\sf{k = \frac{ - 44 + 5}{3} }$

Calculate

⇒ $\sf{k = \frac{ - 39}{3} }$

Divide -39 by 3

⇒ $\sf{k = - 13}$

Hope I helped!

Best regards!!
