Answer:
x=2/5, y=11/5
or x=−1y = 2
Step-by-step explanation:
Substitute y=3x+1 in x2+y2=5 to obtain
x2+(3x+1)2=5 ⇒ 10x2+6x−4=0
Hence
5x2+3x−2=0 ⇒ 5x2+5x−2x−2=0 ⇒5x(x+1)−2(x+1)= 0 ⇒ (5x−2)(x+1)=0
Hence
either
x=2/5, y=3×2/5+1=11/5
or x=−1, y=3×(−1) +1 = −2
Answer:
The mean is 9.
Step-by-step explanation:
How many numbers are there? 6.
The numbers add up to 54.
Divide 54 by 6, to get 9 numbers.
How many boxes are there: 1450 / 120 = 145/12 =12(1/12)
12 boxes have how many popped kernels: 1/12 x 1450 = 1440
What is the remaining popped kernels: 1450-1440=10
Therefore, the last box have 10 popped kernels.
Coefficient is 2
degree is 4
Answer:
B. All demand and supply constraints are satisfied, but cost is ignored
Step-by-step explanation:
The northwest-corner rule is a method to compute the initial feasible solution of a transportation problem.
In this method you start to supply the demand with the northwest-corner option without taking into account the related cost. You assign the whole production of the first source to first demand, if that is more than necessary, then you assign the excess to the second demand, and so on; but if is not enough, then you assign the whole production of the next source to unsatisfied demand. Repeat this procedure until all demands are satisfied.
In the picture attached, an example is given. The table shows the unit transportation cost and in the circles the feasible solution obtained with northwest-corner rule.
