2x+y=-9<br> -3x+11=y whathe is the answer

insens350 [35]

[ 2x + y = -9 ] x -3
[- 3x +11= y ] x 2

-6x -3y = 27
-6x + 22 = 2y

-6x +27 = 3y
-6x +22 = 2y

5 = y

-6x -3x5 = 27
-6x -15 = 27
-6x = 42
-x = 42/6
-x = 7
x = -7

answer

x = -7
y = 5

TU = 3, RS = 15, TW = 4, TR = 9; Assume that the sides of triangle TUW are proportional to the sides of triangle TRS. What is th

VMariaS [17]

Answer:

$WS=8\ units$

Step-by-step explanation:

we know that

If two triangles are similar

then

the ratio of their corresponding sides are equal and the corresponding angles are also equal

In this problem

$\frac{TU}{TR}=\frac{UW}{RS}=\frac{TW}{TS}$

we have

$TU=3\ units, RS=15\ units, TW=4\ units,TR=9\ units$

Find the value of TS

$\frac{TU}{TR}=\frac{TW}{TS}$

substitute

$\frac{3}{9}=\frac{4}{TS}$

$TS=36/3=12\ units$

$WS=TS-TW$

$WS=12-4=8\ units$

see the attached figure to better understand the problem
