Given directed line segment PR below, find the coordinates of Q on PR

g100num [7]

Answer:

$(\frac{4}{3},-3)$

Step-by-step explanation:

The location of a point O(x, y) which divides line segment AB in the ratio a:b with point A at ( $x_1,y_1$ ) and B( $x_2,y_2$ ) is given by the formula:

$x=\frac{a}{a+b}(x_2-x_1)+x_1\\ \\y=\frac{a}{a+b}(y_2-y_1)+y_1$

From the graph, the location of the point is P(2, 5), R(1, -7). Let point Q be (x, y) which divides PR in ratio 2:1. Coordinates of point Q is at:

$x=\frac{a}{a+b}(x_2-x_1)+x_1=\frac{2}{2+1}(1-2)+2=\frac{2}{3}(-1)+2=\frac{4}{3} \\ \\y=\frac{a}{a+b}(y_2-y_1)+y_1=\frac{2}{2+1}(-7-5)+5= \frac{2}{3}(-12)+5=-3$

Point Q is at $(\frac{4}{3},-3)$

rugs Emporium installs carpet for $80 plus $9.50 per square yard of carpet carpets 4 U charges $120 for installation and $7.50 p

mihalych1998 [28]

The area of the carpet must be greater than 20 square yards for which Rugs Emporium charges more than Carpets 4U.

Explanation

Suppose, the number of square yards of carpet is $x$

Rugs Emporium charges $80 plus $9.50 per square yard of carpet. So, the total charge for $x$ square yards of carpet $= (80+9.50x) dollar$

Carpets 4U charges $120 for installation and $7.50 per square yard of carpet. So the total charge for $x$ square yards of carpet $=(120+7.50x) dollar$
