Answer:

I believe it's D.

Step-by-step explanation:

$40 - 25÷100 = $39.75

$39.75 - $5.00 = $34.75

$34.75 - $2 = $32.75.

not confident with my answer though.

hope it helps. :)

First move the constant to the right and change its sign to the opposite,
3m=1-4

Then calculate,
3m=-3

Then divide both sides of the equation by 3,
m=-1

So the answer is m=-1

I have no clue how to do this please help

Answer:

Max = (6,0); min = (-2, 4)  

Step-by-step explanation:

1. Summarize the constraints

\text{Constraints} = \begin{cases}(a)\qquad 2x - y  & \leq 12\\(b)\qquad 4x+ 2y & \geq 0\\(c) \qquad x + 2y  & \leq 6\\ \end{cases}

2. Optimization equation

z = 5x + 2y

3. Graph the constraints to identify the feasible region

See the figure below.

The "TRUE" regions for each graph are the shaded areas to the side of the line indicated by the arrows.

The "feasibility region" is the dark green area where all three areas overlap and all three conditions are satisfied.

5. Determine the points of intersection among the constraints  

(i) Constraints (a) and (b)

\begin{array}{rcr}2x - y  & = & 12\\4x + 2y & = & 0\\4x - 2y & = & 24\\8x&=&24\\x & = & \mathbf{3}\\6 - y & = & 12\\-y & = &6\\y & = & \mathbf{-6}\\\end{array}\\

The lines intersect at (3,-6).

(ii) Constraints (a) and (c)

\begin{array}{rcr}2x - y  & = & 12\\x + 2y & = & 6\\4x - 2y & = &24\\5x & = & 30\\x & = & \mathbf{6}\\6 + 2y & = & 6\\2y & = &0\\y & = & \mathbf{0}\\\end{array}

The lines intersect at (6,0).

(iii) Constraints (b) and (c)

\begin{array}{rcr}4x+ 2y &= & 0\\x + 2y  &=& 6\\3x & = &  -6\\x & = & \mathbf{-2}\\-2 +2y & = & 6\\2y & = &8\\y & = & \mathbf{4}\\\end{array}

The lines intersect at (-2,4).

6. Determine the x- and y-intercepts of the feasible region

The five black dots at (3,-6), (6,0), and (-2,4) are the vertices of the polygon that represents the feasible region.

Each vertex is a possible maximum or minimum of z.  

7. Calculate the maxima and minima

Calculate z at each of the vertices.

(i) At (-2,4)

z = 5x + 2y = 5(-2) + 2(4) = -10 + 8 = 2

(ii) At (3,-6)

z =  5(3) + 2(-6) = 15 - 12 = 3

(iii) At (6,0)

z = 5(6)+ 2(0) = 30 + 0 = 30

The maximum of z occurs at (6,0).

The minimum of z occurs at (-2, 4).

Aaron walks at a pace of 10,560 feet per half hour. How many miles does Aaron
yarga [219]
The answer is 8
you would multiply 10,560 by 4,because there's 4 half hours in 2 hours, and then you get 42,240 and divide that number by 5,280 and you end up with 8.
