Answer:

-15.24m ; 122 m ; 1629 m

Step-by-step explanation:

Representing the elevation of the Given monuments with rational numbers :

The sea level is regarded as a midpoint ; or zero level whereby points below are represented as negative while points above are represented as positive

Cayuga lake = 122 meters above sea level = + 122 meters

Mount Marcy = 1,629 meters above sea level = + 1629 meters

New. York stock exchange vault = 15.24 meters below sea level = - 15.24 m

Arranging from least to highest :

-15.24m ; 122 m ; 1629 m

If y varies directly as the square of x and y = 12 when x = 2 find the value of x when y = 108
dolphi86 [110]
108/12 = 9 so when y = 108 x = 9×2 which = 18 so when y =108 x = 18

PLEASE HELP! WILL UPVOTE!

Just "plug n chug" as my teacher would say. In other words, replace the letters with the values. 

Choice A is (7,19) which means x = 7 and y = 19. Let's replace the x and y value with these numbers in both equations. If we get a true equation, then we found the answer. 

2x-y = -5
2*7-19 = -5
14-19 = -5
-5 = -5 ... true
So that works. Let's try the other equation
x+3y = 22
7+3*19 = 22
7+57 = 22
64 = 22 ... false 
So choice A is NOT the answer because of this. Let's try out choice B
2x-y = -5
2*4-9 = -5
-1 = -5 ... false
so B doesn't work either. How about C? 
2x-y = -5
2*8-21 = -5
-5 = -5 ... that works
x+3y = 22
8+3*21 = 22
71 = 22 ... but this is false
So D has to be the answer. Let's check to confirm or not
2x-y = -5
2*1-7 = -5
-5 = -5 ... true
x+3y = 22
1+3*7 = 22
22 = 22 ... true
BOTH equations are true at the same time so (1,7) is definitely the final answer
