Consider the following pair of equations:

lbvjy [14]

-x-y=-5
-x+y=1

adding up the equations gives;
-2x=-4
x=2

replacing in the first equation;
-2-y=-5
-2+5=y
y=3
They would intersect at (2,3)

What is the best approximation of the length of segment QS? (Note: cos 80° = 0.17)

matrenka [14]

Answer: $QS=11.8cm$

Step-by-step explanation:

1. You have the following information:

- The lenght of $RS$ is 2 centimeters.

- The angle m∠S=80°.

- Cos80°=0.17

2. Therefore, you can calculate the lenght of the segment $QS$ as following:

$cos80=\frac{adjacent}{hypotenuse}$

$adjacent=2cm\\hypotenuse=QS\\cos80=0.17$

3. Substitute values and solve for $QS$ :

$0.17=\frac{2cm}{QS}\\QS=\frac{2cm}{0.17} \\QS=11.76cm$

4. To the nearest tenth:

$QS=11.8cm$

Find the midpoint between A(10,1) and B(5,2)

Alenkasestr [34]

Answer:

midpoint: (7.5, 1.5)

Step-by-step explanation:

midpoint formula: ( (x1 + x2)/2 , (y1 + y2)/2 )

x1= 10

x2= 5

y1=1

y2=2

( 10 + 5 )/2 = 7.5

( 1 + 2 )/2 = 1.5

midpoint coordinates => ( 7.5 , 1.5 )
