Answer: The the speed of elevators is 22.55.
Explanation:
It is given that observation deck of the willis tower in Chicago Illinois is 1353 feet above the ground elevators lift visitors to that level in 60 seconds.
The speed is the change in distance with respect to time.
From the given information the total distance is 1353 and the total time is 60 seconds. So by the above formula we get,
Therefore, the speed of elevators is 22.55.
Xy=11
x+y=-26
x+y=-26
minus x both sides
y=-26-x
sub for y
x(-26-x)=11
-26x-x^2=11
add 26x+x^2 both sides
x^2+26x+11=0
ax^2+bx+c=0

a=1
b=26

ANSWER
(-2,-1)
(3,14)
EXPLANATION
The given system is
or
Equate both of them:
This implies that,
x=-2 or x=3
When x=-2, y=y=3(-2)+5=-1
(-2,-1) is a solution.
When x=3 , y=3(3)+5=14
(3,14) is also a solution.
