<span>Equation (1) x + y = 200
Eauation (2) x = y - 40
x represents the distance from the original location to the firstt city
y represents the
distance from the first city to the second city.
Solution:
(1) x + y = 200
(2) x - y = - 40
----------------------
2x = 200 - 40
2x = 160
x = 160 / 2
x = 80
x + y = 200 => y = 200 - x = 200 - 80 = 120
Therefore the solution (x,y) is (80,120)
Answer: the pair of coordinates that represents the solution (in miles) to this system of
equations is (80, 120) </span>
Answer:
option (B) I'm certain of.
but if you are required to choose more than one then option (B) and (C) since polynomials are coefficients with power 2.
Step-by-step explanation:
Hope this helps.

Answer:
<em>hello your question lacks some information attached below is the complete question</em>
answer : NO
Step-by-step explanation:
Determine the probability of not selecting an obese subject in 3 trials
= P ( not obese in 3 randomly selected ) = ( 1 - 0.111 )^3
= 0.703
The probability > 0.05
hence it is insignificant therefore the answer is NO
