y = - x - 6

Step-by-step explanation:

y = mx + b

m = - 1

y = - x + b

(- 4, - 2)

-2 = 4 + b

b = - 6

y = - x - 6

PLEASe help 30POINTS<br><br> What is the length of segment AB ?

lesya692 [45]

Answer:

$\sqrt{74}$

Step-by-step explanation:

<u>Distance between two points</u>

$d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}$

$\textsf{let}\:(x_1,y_1)=(2,-6)$

$\textsf{let}\:(x_2,y_2)=(7,1)$

$d=\textsf{length of segment AB}$

Substituting points into the distance formula and solving for d:

$\implies d=\sqrt{(7-2)^2+(1-(-6))^2}$

$\implies d=\sqrt{5^2+7^2}$

$\implies d=\sqrt{25+49}$

$\implies d=\sqrt{74}$

A pitcher of water contains 1/4 liters of water. The water is poured equally into 5 glasses. How many liters of water are in eac

Alisiya [41]

We know that

<span>A pitcher of water contains 1/4 liters of water--------------> 0.25 lt
then
0.25 lt/5--------> 0.05 lt

In each glass are 0.05 lt of water
1 lt-------------> 1000 ml
0.05 lt----------> X
X=0.05*1000--------> X=50 ml

the answer is
</span>In each glass are 0.05 lt of water
In each glass are 50 ml of water<span>
