Answer:

B. The domain would only include positive integers.

C. The domain would only include positive numbers.

Step-by-step explanation:

We are given a function that represents the amount of money in the checking account.

As, the function contains the amount of money in the account, the domain cannot have negative values.

So, the domain cannot include all real numbers and it cannot include only integers.

Therefore, the domain can include positive numbers and therefore, it can also include positive integers.

Hence, B and C are correct.

I need help with geometry. Find x.

I am Lyosha [343]

Answer:

Part 9) $x=5$

Part 10) $x=-9$

Step-by-step explanation:

we know that

The Midpoint Theorem states that: The segment joining two sides of a triangle at the midpoints of those sides is parallel to the third side and is half the length of the third side

Part 9) we know that

Point Q is the midpoint segment XY (QY=QX)

Point R is the midpoint segment XW (RW=RX)

Applying the Midpoint Theorem

RQ is parallel to WY

and

$RQ=\frac{1}{2}WY$

we have

$RQ=2x-3\\WY=x+9$

substitute

$2x-3=\frac{1}{2}(x+9)$

solve for x

$4x-6=(x+9)$

$4x-x=9+6$

$3x=15$

$x=5$

Part 10) we know that

Point B is the midpoint segment TS (BS=BT)

Point C is the midpoint segment RS (CS=CR)

Applying the Midpoint Theorem

BC is parallel to TR

and

$BC=\frac{1}{2}TR$

we have

$BC=x+19\\TR=x+29$

substitute

$x+19=\frac{1}{2}(x+29)$

solve for x

$2x+38=(x+29)$

$2x-x=29-38$

$x=-9$

Describe how an infeasible solution occurs

irinina [24]

Answer:

Described

Step-by-step explanation:

A solution becomes infeasible when no solution exit and which satisfies all the constraints. We will consider two basic types of infeasibility. The 1st we will call continuous infeasibility and the second one is discrete or integer infeasibility. Continuous infeasibility is the one where a non–MIP problem is infeasible. In this case the feasible region defined by the intersecting constraints is empty. Discrete or integer infeasibility is the one where a MIP problem has a feasible relaxation (note that a relaxation of a MIP is the problem we get when we drop the discreteness required on the variables) but the feasible region of the relaxation contains no solution that satisfies the discreteness requirement.
