Y = kx is the direct variation equation, where k is the constant of variation.
Find k.

2 = k * 3
2/3 = k

Write the variation equation.
y = (2/3)x

Plug in new value.
y = (2/3)* 9
y = 6

D. The elevator takes 37.5 seconds to move down to the lobby.


8x+y=300

y= 300-8x
y= 300 - 8 (37.5)

y = 300-300
y = 0

wheb y =0 that means that the height is 0

If the ratio of the measure of the complement of an angle to the measure of its supplement is 1:3, find the measure of the angle
prohojiy [21]
Set up and solve an equation:

3(90-x) = (180-x).  Then  270 - 3x = 180 - x, or   270 - 180 = 2x.
                                                                               90 = 2x, so x = 45 deg.

Is this true?     3(90-45) = (180-45)?  If so, x = 45 degrees is correct.

Write an equation in slope intercept form for the line through the two points
Musya8 [376]
m= \frac{y2-y1}{x2-x1}  \\  \\ m= \frac{-2-2}{2-(-2)}  \\  \\ m= \frac{-4}{4}  \\  \\ m=-1


y=mx+b \\  \\ y=-1x+b


(2)=(-1)(-2)+b \\  \\ 2=2+b \\  \\ 0=b


y=-1x+0 \\  \\ y=-x
