w+2x=16 ⇒ w=16-2x

x+2w=14 x+2(16-2x)=14

x+32-4x=14

-3x=14-32

-3x=-18 /:(-3)

x=6

w=16-2x=16-2·6=16-12=4

2y+w=-6 ⇒ 2y+4=-6

2y=-6-4

2y=-10 /:2

y=-5

The number of boxes of cookies you buy or the amount the cookies will cost in dollars which one is independent vairable

qwelly [4]

Answer:

Step-by-step explanation:

When you go shopping for anything, you know that the more of that something you buy, the more money you are going to spend. In other words, the amount of money you spend depends directly upon the amount of stuff you buy. So the number of boxes of cookies you buy is the independent variable and the amount of money you spend on the cookies is the dependent variable.

Find the distance between the points given.<br><br> (-3, 2) and (9, -3)

g100num [7]

The distance will be given by the equation;
D= $\sqrt{( x_{1} - x_{2} )^{2} +( y_{1} - y_{2} )^{2} }$
D= $\sqrt{ (-3-9)^{2}+( 2--3)^{2} }$
D= $\sqrt{ (-12)^{2} + (5)^{2} }$
D= $\sqrt{169}$
D=13 units
